  • GW Experts Available: White House Announces AI Safety Pledge with Top Tech Companies

    GW Experts Available: White House Announces AI Safety Pledge with Top Tech Companies

    [ad_1]

    Seven leading companies building artificial intelligence – including Google, Amazon, Microsoft, Meta and Chat GPT-maker OpenAI – have agreed to a voluntary pledge to mitigate the risks of AI, according to an announcement by the White House. The companies committed to allowing independent security experts to test their systems before they’re released and to develop systems that will alert the public when content is created by AI, through a method known as “watermarking,” among other pledged steps. 

    GW faculty experts are available to offer insight, analysis and commentary on responsible and trustworthy AI as well as efforts by lawmakers and the Biden Administration to regulate artificial intelligence.


    David Broniatowski, an associate professor of engineering management and systems engineering, is GW’s lead principal investigator of a newly launched, NSF-funded institute called TRAILS that explores trustworthy AI. Broniatowski is leading the institute’s third research arm of evaluating how people make sense of the AI systems that are developed, and the degree to which their levels of reliability, fairness, transparency and accountability will lead to appropriate levels of trust. He can discuss the risks and benefits of AI development and what developing trustworthy AI means and looks like.

    Broniatowksi says watermarking is a useful tool, but there is no evidence that it will mitigate risks of AI harms on its own.

    Susan Ariel Aaronson, research professor of international affairs, is the director of GW’s Digital Trade and Data Governance Hub and co-PI of the TRAILS Institute. Under the TRAILS research initiative, Aaronson is using her expertise in data-driven change and international data governance to lead one of the institute’s research arms in participatory governance and trust. In all, her research focuses on AI governance, data governance, competitiveness in data-driven services such as XR and AI and digital trade. She can discuss the latest efforts to regulate artificial intelligence.

    Immigration experts on Title 42, analysis of immigration policies, and other migrant news in the Immigration Channel

    [ad_1]

    Title 42, the United States pandemic rule that had been used to immediately deport hundreds of thousands of migrants who crossed the border illegally over the last three years, has expired. Those migrants will have the opportunity to apply for asylum. President Biden’s new rules to replace Title 42 are facing legal challenges. The US Homeland Security Department announced a rule to make it extremely difficult for anyone who travels through another country, like Mexico, to qualify for asylum. Border crossings have already risen sharply, as many migrants attempted to cross before the measure expired on Thursday night. Some have said they worry about tighter controls and uncertainty ahead. Immigration is once again a major focus of the media as we examine the humanitarian, political, and public health issues migrants must face.

  • ORNL malware ‘vaccine’ generator licensed for Evasive.ai platform

    ORNL malware ‘vaccine’ generator licensed for Evasive.ai platform

    [ad_1]

    Newswise — Access to artificial intelligence and machine learning is rapidly changing technology and product development, leading to more advanced, efficient and personalized applications by leveraging a massive amount of data.

    However, the same abilities also are in the hands of bad actors, who use AI to create malware that evades detection by the algorithms widely employed by network security tools. Government agencies, banking institutions, critical infrastructure, and the world’s largest companies and their most used products are increasingly under threat from malware that can evade anti-virus systems, hijack networks, halt operations and expose sensitive and personal information.

    A technology developed at the Department of Energy’s Oak Ridge National Laboratory and used by the U.S. Naval Information Warfare Systems Command, or NAVWAR, to test the capabilities of commercial security tools has been licensed to cybersecurity firm Penguin Mustache to create its Evasive.ai platform. The company was founded by the technology’s creator, former ORNL scientist Jared M. Smith, and his business partner, entrepreneur Brandon Bruce.

    “One of ORNL’s core missions is to advance the science behind national security,” said Susan Hubbard, ORNL’s deputy for science and technology. “This technology is the result of our deep AI expertise applied to a big challenge — protecting the nation’s cyber- and economic security.”

    Smith, who worked in ORNL’s Cyber Resilience and Intelligence Division for six years, created the technology — the adversarial malware input generator, or AMIGO — at the request of the Department of Defense. AMIGO was created as the evaluation tool for a challenge issued by NAVWAR for AI applications that autonomously detect and quarantine cybersecurity threats. NAVWAR is an operations unit within the Navy that focuses on secure communications and networks.

    “ORNL’s Cyber Resilience and Intelligence Division is a world leader in cybersecurity technology,” said Moe Khaleel, associate laboratory director for the lab’s National Security Sciences Directorate. “Moving AMIGO into the marketplace will help protect our nation’s critical infrastructure from attack.”

    “We put AMIGO to the test in a realistic environment. It’s been through the wringer and has been validated at a high technical readiness level,” Smith said. “The core technology is designed to build evasive malware, like a virus, that can bypass an existing detection technology.”

    Drawing on more than 35 million malware samples — some publicly available and others never before seen — AMIGO generates optimally evasive malware in tandem with the training information needed for a security system to detect it in the future.

    Smith likens the process to vaccine development. “It’s as if we generated a million virus variants and a million vaccines to protect against them — we can collapse that into one vaccine and inoculate everyone. They’re protected against the threat, but also all the natural evolutions of the threat going forward.”

    Luke Koch, who in 2019 worked on the AMIGO development team through the DOE Office of Science’s SULI, or Science Undergraduate Laboratory Internship program, is now a doctoral student at the Bredesen Center for Interdisciplinary Research and Graduate Education, a collaboration between ORNL and the University of Tennessee, as well as a graduate research assistant in ORNL’s Cybersecurity Research Group. With Smith’s direction, Koch wrote the binary instrumentation code used in AMIGO.

    “Cybersecurity commercialization is important because our adversaries are always probing for weaknesses throughout the supply chain,” Koch said. “One single flaw is all it takes to invalidate a clever and expensive defense.”

    Amid a growing public understanding of the power of AI, the team is eager to see AMIGO integrated into Evasive.ai and implemented by national security agencies to protect government assets and infrastructure.

    “Bad actors are already using artificial intelligence to advance their attacks,” Bruce said. “As open AI tools improve, attempts to penetrate security systems will increase in volume and sophistication.”

    Additionally, long-term use of the Evasive.ai platform could inform a more complete understanding of the mechanisms that contribute to adversarial samples. This insight will make the next generation of machine learning defenses more robust.

    And what does any of this have to do with penguins? The company’s playful name is a riff on the problem of a small mutation enabling a virus to evade existing defenses — a penguin disguised with a mustache.

    ORNL commercialization manager Andreana Leskovjan negotiated the terms of the license.

  • After one year of war, how to break the stalemate in Ukraine?

    After one year of war, how to break the stalemate in Ukraine?

    [ad_1]

    February 24 will mark one year since Russian tanks rolled over the border into Ukraine. As it stands there is still no end in sight and the U.S. is facing increasing pressure to provide military aid in the form of high tech equipment such as F-16 fighters and M1 Abrams tanks.

    David Silbey is an associate professor of history at Cornell University where he specializes in military history, defense policy and battlefield analysis. He says the war in Ukraine is starting to resemble the kind of proxy conflicts we saw during the Cold War.

    Silbey says:

    “The United States is gaining a substantial geopolitical advantage at low cost to itself while the Russians are bleeding themselves dry against a defiant enemy.  

    “For 2023, I wouldn’t be surprised if the U.S. eventually sends fighter jets, though like tanks, it’s going to take them a while to get there and then train Ukrainians on them. They would be a substantial military help but also a challenging logistics burden for Ukraine.

    “I seriously doubt American forces will get sent to Ukraine. I suspect there may already be U.S. special forces in-country, (though I have no evidence). It would escalate the war massively if regular troops were sent in, which is something the U.S. doesn’t need to do at the moment.”

    Cristina Florea is an assistant professor and historian of Central and Eastern Europe.

    She says the Russian-Ukrainian war has become a war of attrition, where a Ukrainian victory is far from guaranteed.

    Florea says:

    “Despite Ukrainians’ unwavering will to fight, the fact of the matter remains that over one fifth of Ukraine’s territory is currently in Russian hands. What worries me is that after one year of fighting, the conflict will gradually recede into the background, and concern will give way to complacency.

     “The war’s end will be decided on the battlefield. Since there are no signs that Russian support for the war is any weaker today, it is imperative that the U.S. and NATO throw their weight fully behind Ukraine. Halfway measures will simply prolong the conflict and put Ukraine at risk of running out of military equipment before Russia does.”

  • Terror under lockdown: Pandemic restrictions reduce ISIS violence

    Terror under lockdown: Pandemic restrictions reduce ISIS violence

    [ad_1]

    Newswise — New Haven, Conn. — Lockdown measures aimed at slowing the spread of COVID-19 had the unintended benefit of curtailing violence by the insurgent group ISIS, according to a new study led by Yale political scientist Dawn Brancati.

    The study, published on Jan. 30 in the journal American Political Science Review, found that government-imposed curfews and travel bans instituted to protect public health in Iraq, Syria, and Egypt were significantly associated with a reduction in ISIS attacks, especially in urban areas and locations outside the militant organization’s base of operations.

    “Although ISIS leaders vowed to ramp up attacks during the pandemic, our analysis found that pandemic lockdown measures likely reduced the group’s attacks by depleting its financial resources, reducing high-value civilian targets, and making it logistically more difficult for ISIS to conduct attacks by reducing its cover,” said Brancati, a senior lecturer in the Department of Political Science in Yale’s Faculty of Arts and Sciences. “Our findings provide important insights into the effects of public health measures on violence by non-state actors like ISIS, al-Qaeda, and Boko Haram, as well as the general effectiveness of curfews and travel restrictions as counterinsurgency tools.”

    In examining the effects of the lockdown measures on violence by non-state actors, Brancati — along with coauthors Jóhanna Birnir of the University of Maryland-College Park and Qutaiba Idlbi of the Atlantic Council — focused on ISIS due to the group’s explicit pledge to accelerate violence during the pandemic and because its large financial reserves, rural base, and preference for targeting government installations over civilians make it less vulnerable to the effects of curfews and travel restrictions.

    The researchers analyzed data on more than 1,500 ISIS-initiated violent events in Iraq, Syria, and Egypt — the countries where the group launches most of its attacks — compiled by the Armed Conflict Location and Event Data Project covering a 78-week period between Dec. 31, 2018, and June 28, 2020. In March 2020, pandemic-related curfews and travel bans were imposed in all three countries and were in place for three to four months. The researchers also mapped the number and location of ISIS attacks within and across Iraq’s governorates using geographic information system (GIS).

    The public health measures significantly reduced violence, especially in cities and areas outside of the militant group’s rural bases, the study showed. For example, the number of violent events was about 30% lower in Iraq and 15% lower in Syria when COVID-19 related curfews were in place in these countries.

    The researchers found that the higher a governorate’s population, the more effective curfews were in reducing violence. For example, the number of ISIS-initiated violent events in the governorate of Baghdad, which has a population of 8.1 million, was 11% lower when the curfews were in place. There was no change in the Iraqi governorate of Najaf (a center of Muslim pilgrimage, surpassed by only Mecca and Medina), which has a population of 1.5 million people.

    Based on interviews with government officials, military leaders, policy experts, and residents of places covered in the study, the researchers concluded that the curfews and travel restrictions reduced the number of high-value civilian targets and made it more difficult for ISIS militants to move about without being noticed. While there is evidence that the public health measures also strained the group’s financial resources — for instance, by limiting its ability to collect money from locals or operate its commercial businesses — the group’s financial reserves, which amount to hundreds of millions of dollars by most estimates, likely allowed it to keep funding its cells, the researchers concluded.

    Given that pandemic lockdown measures seem to have hindered ISIS’s ability to initiate violence, they likely have similar or greater effects on other violent non-state organizations, the researchers said.

    “Most non-state actors lack ISIS’s financial resources, tend to target civilians more heavily, and operate in urban areas, which suggests they would be more vulnerable to the effects of lockdown measures than ISIS is,” Brancati said. “This does not suggest that lockdown measures are a magic bullet in fighting insurgencies since they have harsh side effects on society, especially in developing countries where militant groups operate.”

  • Tracking Explosions with Toughened-Up Tracers

    Tracking Explosions with Toughened-Up Tracers

    [ad_1]

    Newswise — What happens in an explosion? Where do the products of that explosion go following the blast? These questions are often difficult to solve. New rugged tracer particles, developed by Pacific Northwest National Laboratory (PNNL) researchers, can provide some answers.

    Beyond explosives, many industries may be interested in tracking particulates through harsh environments—which often include high pressures, high temperatures, and different chemicals.  

    “Lots of chemical tracers exist,” said Lance Hubbard, materials scientist supporting PNNL’s national security research. “The challenge is developing one that can survive harsh environments. It took a few years to convince anyone we could do it.”

    Hubbard and his team, along with fellow PNNL researchers April Carman and Michael Foxe, created a tracer that could not only survive but thrive in extreme conditions. Their work was published in MRS Communications.

    Quantum dots and water-soaked glass

    Organic materials, such as fluorescent dyes, are commonly used as tracers for water leaks and tracking cells in biological experiments. While they work great in those conditions, they aren’t so good for tracing material in explosions. Their problem?

    “They burn,” said Hubbard.

    Instead, Hubbard and his team focused on inorganic materials to develop their rugged tracers—particularly quantum dots. Though they fared much better than organic materials in harsh conditions, the research team still needed to protect the quantum dots from the extreme conditions of a chemical explosion.

    “Finding a way to protect the tracer while still maintaining its luminescent intensity proved to be difficult,” said Carman.

    The tracer’s brightness—or luminescent intensity—can be greatly affected by the local environment. Some protective methods can diminish the brightness, making the tracer more difficult to detect. The team focused on using hydrated silica—“basically water-soaked glass” as Hubbard puts it—to protect the quantum dots and maintain their brightness.

    Though previous silica coating methods significantly decreased tracer luminescence, the coated tracers designed by the PNNL team were almost as bright as the original quantum dots. Further testing showed that the particles could survive for long periods of time through a range of pH conditions.

    “We knew we created something special when we saw our results,” said Hubbard.

    Making tracers tunable and mass-producible

    Special is one thing, but useable on the commercial scale is another. Lucky for the PNNL team, their synthesis method was designed from the get-go to be completely scalable to produce mass quantities—from kilograms to potential tons per day.

    Not only can they make large amounts of the tracer, but they can customize them as well. “We can tune both the tracer’s size and color to any specificity,” said Foxe. “The tracer can be fine-tuned to create a mimic of the mass or material that is being tracked. We can also use a variety of sizes with different colors to visualize how an explosion affects particles of different sizes.”

    The tracers are rugged enough to be deployed in harsh environments to track mass and improve scientists’ understanding of environmental fate and transport. They can function under conditions that are too severe for traditional tracers—like in oil and gas refineries or geothermal plants. With tunable parameters and an easy-to-use system, these tracers have many potential applications for tracking material fate and transport in harsh environments.

    Persistence pays off

    The research has now grown from a small initial investment from the National Nuclear Security Administration (NNSA), Defense Nuclear Nonproliferation Research and Development program to encompassing several related projects.

    “We are glad we could keep pursuing this project despite initial skepticism,” said Carman. “We are also thrilled to see where it leads us next.”

    Additional PNNL authors on this research are Clara Reed, Anjelica Bautista, Maurice Lonsway, Nicolas Uhnak, Ryan Sumner, Trevor Cell, Erin Kinney, Nathaniel Smith, and Caleb Allen. Scientists and engineers from Los Alamos National Laboratory, Lawrence Livermore National Laboratory, Mission Support and Test Services LLC, and Sandia National Laboratories also contributed to the project.

  • There’s no evidence that U.S. aid money sent to Ukraine was then used to invest in FTX as a money laundering scheme

    There’s no evidence that U.S. aid money sent to Ukraine was then used to invest in FTX as a money laundering scheme

    [ad_1]

    The news that FTX, the cryptocurrency company, filed for bankruptcy protection amid news it was short billions of dollars has spawned many conspiracy theories being shared on social media. Viral tweets like this one posted on November 13th claim that U.S. aid to Ukraine was laundered back to the Democratic Party through the failed cryptocurrency exchange firm FTX. An article in the conservative site The Gateway Pundit with the headline “Tens of Billions of US Dollars Were Transferred to Ukraine and then Using FTX Crypto Currency the Funds Were Laundered Back to Democrats in US” was shared widely on social media. There is no evidence to support this claim. The Ukrainian government has not invested nor stored money in FTX, according to the country’s Ministry of Digital Transformation. The claim has been rated False.

    Dr. Nigel Williams, a Reader in Project Management at the University of Portsmouth has this to say…

    The collapse of FTX was catalyzed by a tweet on Sunday, November 6th, by the CEO of Binance, Changpeng Zhao: 

    As part of Binance’s exit from FTX equity last year, Binance received roughly $2.1 billion USD equivalent in cash (BUSD and FTT). Due to recent revelations that have came to light, we have decided to liquidate any remaining FTT on our books. 1/4

    Before this date, however, FTX’s actions were heavily scrutinized by conservative commentators on Twitter despite the fact that FTX donated to both political parties. Even before the collapse, efforts were made to link FTX’s actions to the Democratic Party. For example, on November 4th, Wayne Vaughan, CEO of Tieron tweeted, “Sam [Sam Bankman-Fried. former CEO of FTX] is one of the largest Democrat donors. It’s logical that he’d want to get the bill done before Republicans take control of Congress.”

    On November 8, when it became clear that FTX was floundering, commentators attempted to blame the company’s troubles on their political involvement (example here).  While the results were being tallied, early conspiracy theories emerged (example here). These theories later evolved into the story that now links FTX, the Democrats, and the ongoing conflict in Ukraine when it became clear that the Democratic party performed better than the previous media narrative would suggest.

    While FTX’s bankruptcy has begun to offer insights into possible gaps in financial controls that resulted in their collapse, the full story will not be known until detailed audits are completed. To date, the promoters of the FTX/Ukraine/Democrat narrative have not offered any supporting evidence for their theory.  This is, of course easily explained by these promoters who claim that there is a cover-up and no evidence would be available.

  • Latest US Drone Transfer to Ukraine Signals Shift in ‘Character of War’

    Latest US Drone Transfer to Ukraine Signals Shift in ‘Character of War’

    [ad_1]

    Newswise — General Atomics, the U.S.-based manufacturer of the most advanced armed and networked drone in the world – the MQ-9 Reaper – announced it intends to deliver the capability to Ukraine as part of a broader U.S. defense aid package.

    Paul Lushenko is a lieutenant colonel in the U.S. Army and senior policy fellow at Cornell University’s Tech Policy Lab, as well as a doctoral student and co-editor of “Drones and Global Order: Implications of Remote Warfare for International Society.”

    Lushenko says:

    “While the exact timing of the transfer is unclear, the announcement is significant. It signals that U.S. officials have updated their belief for the escalatory potential of providing armed and networked drones to Ukraine, which previously stalled a decision for a potential arms transfer.

    “It suggests that U.S. officials now believe that armed and networked drones have an important role to play in large-scale war, and not just counterterrorism. It also implies U.S. officials are now willing to assume risk for the potential loss of armed and networked drones in Ukraine – an unacceptable prospect weeks ago. 

    “Congressional approval for the sale of armed and networked drones to Ukraine seems to indicate that U.S. officials believe that the conflict has moved into a new phase where drones may play an increasingly important – perhaps the decisive – role. It also suggests that the U.S. is now embroiled in an ‘arms race’ for drones. While this may not change the nature of war, or why it’s fought, it will have important implications for the character of war, or how it’s fought, going forward.”

  • The COVID pandemic is over? Not quite there, say scientists

    The COVID pandemic is over? Not quite there, say scientists

    [ad_1]

    Newswise — In widely covered remarks during an interview with 60 Minutes correspondent Scott Pelley, President Biden claimed, “the pandemic is over.” Biden elaborated, adding, “we still have a problem with COVID, we’re still doing a lot of work on it, but the pandemic is over. If you noticed, no one’s wearing masks, everybody seems to be in pretty good shape. And so I think it’s changing, and I think this is a perfect example of it.” 

    According to the Washington Post, Biden’s remarks caught some senior officials off guard, particularly since the U.S. government has started its fall vaccination campaign. Although the Centers for Disease Control and Prevention announced more relaxed COVID-19 guidelines last month, the agency specifically said that the pandemic was not over in a press release issued on August 11th. Therefore, this statement has earned a rating of “Half True.”

    With the rollout of boosters of life-saving vaccines, new treatments, and a large population already infected, the U.S. is in a less vulnerable place than it was in 2020.  However, the death toll, while lower than before, is still at around 400 deaths per day from COVID-19 in the U.S. Many health experts say we’re not out of the woods yet.

    “Saying that the pandemic is over has much larger and more serious ramifications, it means we take away resources allocated by Congress and other agencies. We must be careful about saying it is over. We still need resources to continue vaccination and to address vaccine hesitancy.” says Bernadette Boden-Albala, MPH, DrPH, Founding Dean and Director of the UCI Program in Public Health.

    The end of masking restrictions and relaxing of other major guidelines has given many Americans a sense of moving on from the national health crisis that has festered for more than two years. Biden’s remarks, though perhaps an oversimplification, reflect national sentiment. However, COVID-19 is still very much evident in our U.S. population, and will likely continue for the foreseeable future. 

    “This is in great part due to human behaviors and motivations,” says Halkitis, “including subpar vaccination uptake, which continues to place all of us at risk for infection.”

  • Herschel Walker’s claim on how China’s “bad air” would move over to America is grossly inaccurate

    Herschel Walker’s claim on how China’s “bad air” would move over to America is grossly inaccurate

    [ad_1]

    At a campaign event in Georgia, Herschel Walker, the former NFL star who is running for Senate and endorsed by President Trump, shared his thoughts on the “Green New Deal” and efforts to curb climate change with government policy. Walker suggested that U.S. climate efforts were pointless because “China’s bad air” would simply move over into American “air space.” 

    “We in America have some of the cleanest air and cleanest water of anybody in the world,” Walker begins at about the 24 mark in the video of his speech. Under the Green New Deal, he said, the U.S would spend “millions of billions of dollars cleaning our good air up. … Since we don’t control the air, our good air decided to float over to China’s bad air so when China gets our good air, their bad air got to move. So it moves over to our good air space. Then now we got to clean that back up, while they’re messing ours up.”

    “So what we’re doing is just spending money,” he continued. “Until these other countries can get on board and clean what they got up, it ain’t going to help us to start cleaning our stuff up. We’re already doing it the right way.”

    We find nearly every aspect of this claim to be completely inaccurate. Walker’s description of how air circulates around the world is not correct, nor is the simplification of his assessment of “clean air” and “bad air.” The United States does not actively “clean” air now or under the proposed “Green New Deal.” The “Green New Deal” is a nonbinding resolution introduced in Congress in 2019 that lays out a broad vision for how the country might tackle climate change over the next decade in order to achieve net-zero greenhouse gas emissions. It didn’t pass the Senate vote. The Green New Deal does not address traditional air pollutants nor does it propose to spend “millions of billions of dollars cleaning our good air up.” Facts on the “Green Neal Deal” can be read here.

    “Bad” air does not take over “good” air or vice versa. Yes, some forms of air pollution can travel to other places. Near-surface pollutants, such as sulfur dioxide and particulate matter, can be lofted to high altitudes where strong winds can transport high concentrations across oceans to other continents. However, greenhouse gases, primarily carbon dioxide, are responsible for climate change. These greenhouse gasses accumulate in the Earth’s atmosphere on a global scale as a result of human activity, particularly the burning of fossil fuels, which traps heat and warms the entire planet. Also, to suggest curbing pollutants from its local source is pointless because some other locality’s pollutants will take over is missing the point. These harmful air pollutants affect local residents the most. Read more about the harmful effects of air pollution here, here and here

    As reported by Jessica McDonald at Factcheck.org

    “Each of these gases can remain in the atmosphere for different amounts of time, ranging from a few years to thousands of years,” the Environmental Protection Agency has explained. “All of these gases remain in the atmosphere long enough to become well mixed, meaning that the amount that is measured in the atmosphere is roughly the same all over the world, regardless of the source of the emissions.”

    “There can be enhanced concentrations near point sources and urban areas, but the levels of atmospheric CO2 over the US aren’t drastically different than over China,” Davis said in an email, referring to carbon dioxide. He noted that in April 2020, carbon dioxide levels over China and the U.S were within three to four parts per million of each other.

    In other words, there is no American “good air” or Chinese “bad air.” When it comes to greenhouse gases, everyone ultimately shares the “air” — and the concentration of heat-trapping gases in the atmosphere is increasing. This is raising the global average temperature, which is also causing other effects, such as sea level rise, ice melt and more extreme weather.

  • Abe assassination is a rare act of gun violence in Japan

    Abe assassination is a rare act of gun violence in Japan

    [ad_1]

    Following the horrific mass shootings in the United States, social media is rife with discussions on gun laws and regulations. Friday morning’s news of the assassination of former Japanese Prime Minister Shinzo Abe by a gunman has brought the issue of strict laws on gun ownership to light. How could this happen in a country with only one firearm-related death in all of 2021? Since 2017, there have been 14 gun-related deaths in Japan, a remarkably low figure for a country of 125 million people. Compare that to the 45,222 people who died from gun-related injuries in the U.S. in just one year (2021).1

    Republican Congressional candidate Lavern Spicer has chimed in on this shocking assassination by tweeting, “How did Shinzo Abe get assassinated when guns are banned in Japan? Liberals, care to explain?” Her tweet was shared by thousands. We find this claim to be misleading and inaccurate.

    Firstly, guns are not banned in Japan but are regulated by very strict gun ownership laws. 

    This backgrounder by the Council on Foreign Relations explains how guns are regulated in Japan…

    Gun control advocates regularly cite Japan’s highly restrictive firearm regulations in tandem with its extraordinarily low gun death rate. Most years, fewer than one hundred Japanese die from gun violence in a country of 125 million people. Most guns are illegal in the country and ownership rates, which are quite low, reflect this.

    Under Japan’s firearm and sword law [PDF], the only guns permitted are shotguns, air guns, guns with specific research or industrial purposes, or those used for competitions. However, before access to these specialty weapons is granted, one must obtain formal instruction and pass a battery of written, mental, and drug tests and a rigorous background check. Furthermore, owners must inform the authorities of how their weapons and ammunition are stored and provide their firearms for annual inspection.

    Some analysts link Japan’s aversion to firearms with its demilitarization in the aftermath of World War II. Others say that because the overall crime rate in the country is so low, most Japanese see no need for firearms.

    Secondly, by asking “liberals” to explain, Spicer is suggesting that gun laws don’t prevent gun violence, since those who identify with “liberal” political beliefs tend to support stricter gun control measures. However, the simple fact that this act of violence is so rare in Japan supports the idea that gun control in Japan is working. Yes, culture is one reason for the low rate, but gun regulation is a major one, too. The result is a situation where citizens and police seldom use guns. The fact that the shooter of Shinzo Abe most likely used a “homemade gun”2 to get past laws restricting the sales of firearms and ammunition, proves that guns are harder to obtain in Japan. 

    According to a recently published article on Vox, gun regulations in other countries reflect a significant difference in recorded instances of gun violence. 

    No other high-income country has suffered such a high death toll from gun violence. Every day, more than 110 Americans die at the end of a gun, including suicides and homicides, an average of 40,620 per year. Since 2009, there has been an annual average of 19 mass shootings, when defined as shootings in which at least four people are killed. The US gun homicide rate is as much as 26 times that of other high-income countries; its gun suicide rate is nearly 12 times higher.

    The following excerpt published in The Guardian by reporters Cait Kelly and Justin McCurry compares gun violence in U.S. and Japan and other high-income countries.

    A 2022 report from the University of Washington revealed that, while the US had more than four firearm homicides per 100,000 people in 2019, Japan had almost zero. Comparing high-income countries in the World Bank with the rate of firearm homicide per 100,000 people, the US had 4.2, Australia had 0.18 and Japan 0.02, the report found.

    In 2013, the country hit a record high for gun crime, with 40 criminal cases of guns being fired, but it has followed a downward trend since.

    There are also strict laws about how many gun shops are allowed to open – in most of the countries’ 47 prefectures, a total of three gun shops can operate in each prefecture.
