• Handgun Purchaser Licensing Laws Associated with Lower Firearm Homicides, Suicides

    State handgun purchaser licensing laws—which go beyond federal background checks by requiring a prospective buyer to apply for a license or permit from state or local law enforcement—appear to be highly effective at reducing firearm homicide and suicide rates, according to a new analysis of gun laws.

  • Police solve just 2% of all major crimes

    As Americans across the nation protest police violence, people have begun to call for cuts or changes in public spending on police. But neither these nor other proposed reforms address a key problem with solving crimes. My recent review of fifty years of national crime data confirms that, as police report, they don’t solve most serious crimes in America. In reality, about 11 percent of all serious crimes result in an arrest, and about 2 percent end in a conviction. Therefore, the number of people police hold accountable for crimes – what I call the “criminal accountability” rate – is very low.

  • QAnon Conspiracies on Facebook Could Prompt Real-World Violence

    As Facebook continues to grapple with hate speech and violent extremism across the platform, QAnon conspiracy theorists are using public and private Facebook pages and groups to spread disinformation, racism, and thinly veiled incitement to violence. This conspiracy is estimated to have a Facebook audience of millions of users.

  • New Detection Method to Protect Army Networks

    U.S. Army researchers developed a novel algorithm to protect networks by allowing for the detection of adversarial actions that can be missed by current analytical methods. The main idea of this research is to build a higher-order network to look for subtle changes in a stream of data that could point to suspicious activity.

  • One Step Closer to Bomb-Sniffing Cyborg Locusts

    Researchers found that they could direct locust swarms toward areas where suspected explosives are located, and that the locusts’ brain reaction to the smell of explosives can be read remotely. Moreover, a study found locusts can quickly discriminate between different smells or different explosives. “This is not that different from in the old days, when coal miners used canaries,” says a researcher. “People use pigs for finding truffles. It’s a similar approach — using a biological organism — this is just a bit more sophisticated.”

  • Lethal Autonomous Weapons May Soon Make Life-and-Death Decisions – on Their Own

    With drone technology, surveillance software, and threat-predicting algorithms, future conflicts could computerize life and death. “It’s a big question – what does it mean to hand over some of the decision making around violence to machines, and everybody on the planet will have a stake in what happens on this front,” says one expert.

  • Fear of Stricter Regulations Spurs Gun Sales after Mass Shootings: Study

    Researchers used data science to study why gun sales tend to go up after a mass shooting. By working with spatio-temporal data from all the states in the United States, they determined that the increase in firearm purchases after mass shootings is driven by a concern about regulations rather than a perceived need for protection.

  • How a New Administration Might Better Fight White Supremacist Violence

    In the last four years, violence linked to white supremacy has eclipsed jihadi violence as the predominant form of terrorism in the United States, the Brookings Institution’s Dan Byman writes. “U.S. bureaucracies are slowly moving forward despite discouragement or indifference from on high,” he writes, noting that DHS has elevated the importance of white supremacist violence, and that the State Department has designated the Russian Imperial Movement (RIM), an ultranationalist white supremacist group, as a terrorist organization — the first time the State Department ever designated a white supremacist group as such. What might a new administration do to more effectively target white supremacist violence? Byman highlight seven areas in which the new administration may want to take action

  • Might Technology Tip the Global Scales?

    Benjamin Chang, a fourth-year MIT graduate student, is assessing the impacts of artificial intelligence on military power, with a focus on the U.S. and China. “Every issue critical to world order — whether climate change, terrorism, or trade — is clearly and closely intertwined with U.S.-China relations,” says Chang. “Competition between these nations will shape all outcomes anyone cares about in the next 50 years or more.”

  • Justice Department Completes Review of Errors in FISA Applications

    The 2016 application by the FBI to the FISA court for permission to place Carter Page, a former Trump campaign adviser, under surveillance over his suspicious contacts with Russian intelligence officers, was reviewed by the Justice Department’s Inspector General. The DOJ IG found the application to be proper and in line with the department’s guidelines, even though it contained a few minor errors. AG William Barr ordered a second thorough review of the FBI’s application, a review which included a review of the IG’s review as well. The Barr-ordered review has been completed, and the Justice Department reported that most of the errors identified by the Office of the Inspector General were minor, and none invalidated the surveillance application and authorizations. The DOJ review “should instill confidence in the FBI’s use of its FISA authorities,” said FBI Acting General Counsel Dawn Browning, committed the agency to “meeting the highest standard of exactness” and “eliminat[ing] errors of any kind.”

  • Testing Interoperability, Compatibility of Next Generation 911 systems

    Next Generation 911 (NG911) is an updated version of the current nationwide emergency response system operating on an Internet Protocol (IP) platform that will enable voice, video, photographs, text, and future communications technologies to be transmitted to and by the public and first responders for assistance. The Critical Infrastructure Resilience Institute (CIRI), a DHS Center of Excellence led by the University of Illinois at Urbana-Champaign (UIUC), will develop a framework and process for testing the interoperability and compatibility of NG911 systems.

  • ‘Deepfakes’ Ranked as Most Serious AI Crime Threat

    Fake audio or video content has been ranked by experts as the most worrying use of artificial intelligence in terms of its potential applications for crime or terrorism. : “As the capabilities of AI-based technologies expand, so too has their potential for criminal exploitation. To adequately prepare for possible AI threats, we need to identify what these threats might be, and how they may impact our lives,” says one expert.

  • Nuclear Threats Are Increasing – Here’s How the U.S. Should Prepare for a Nuclear Event

    On the 75th anniversary of the bombings of Hiroshima and Nagasaki, some may like to think the threat from nuclear weapons has receded. But there are clear signs of a growing nuclear arms race and that the U.S. is not very well-prepared for nuclear and radiological events. Despite the gloomy prospects of health outcomes of any large-scale nuclear event common in the minds of many, there are a number of concrete steps the U.S. and other countries can take to prepare. It’s our obligation to respond.

  • Real-time Imaging to Help Prevent Deadly Dust Explosions

    Dust explosions can be among the most dangerous and costly workplace incidents. Dust builds up in agricultural, powder-handling or manufacturing settings, causing hazards to employees and posing the risk of exploding. Researchers have developed an image- and video-based application using OpenCV algorithms that detect explosible suspended dust concentration.

  • Hundreds of Domestic Terrorism Investigations Opened Since Start of George Floyd Protests: Officials

    The FBI has opened more than 300 domestic terrorism investigations since late May and arrested nearly 100 people in Portland, Oregon, a focal point of the George Floyd protests, a top federal prosecutor said on Tuesday. The investigations are conducted by a recently formed Justice Department task force on “antigovernment extremists.” Last year, FBI Director Christopher Wray said most of the bureau’s domestic terrorism cases are linked to white supremacy, but the when lawmakers pressed Erin Nealy Cox, co-director of the task force, why the Justice Department “has stopped tracking white supremacist incidents as a separate category of domestic terrorism,” Cox said she did not know.
