• Improved technology to detect hazardous chemicals

    Scientists have developed a system quickly to detect trace amounts of illegal drugs, explosives, pollutants in rivers, or nerve gases released into the air; the new system can pick out a single target molecule from 10,000 trillion water molecules within milliseconds, by trapping it on a self-assembling single layer of gold nanoparticles

  • Arizona police departments test shirt-worn, high-tech cameras

    Two police departments in Arizona – Surprise and Peoria — are testing several brands of high-tech cameras that attach to an officer’s shirt; police in Mesa, Arizona used about fifty cameras for a 1-year study; the Phoenix Police Department plans on using the cameras full-time starting early next year; privacy and civil-liberties experts say the cameras can be used in a positive way, but that there needs to be a clear baseline of rules when it comes to how and when the cameras are used

  • Nanotech detection device emulates dog's nose to detect explosives

    Inspired by the biology of canine scent receptors, scientists develop a chip capable of quickly identifying trace amounts of vapor molecules; the chip is part of a device which is both highly sensitive to trace amounts of certain vapor molecules, and able to tell a specific substance apart from similar molecules

  • License plate scanners in Canada under fire from privacy commissioners

    British Columbia’s privacy commissioner is not happy about the way police departments are using their license-plate scanners; in a report released last week, Commissioner Elizabeth Denham said changes must be made to the Victoria police department’s Automated License Plate Recognition Program (ALPR), after it was discovered that the program could be used as a surveillance tool

  • DARPA seeking surveillance technology to predict future behavior

    DARPA has teamed up with scientists from Carnegie Mellon University to create an artificial intelligence system that can watch and predict what a person will “likely” do in the future, using specially programmed software designed to analyze various real-time video surveillance feeds; the system can automatically identify and notify officials if it recognized that an action is not permitted, detecting what is described as anomalous behaviors

  • Scanning social media as a tool for biosurveillance

    DHS is considering observing and scanning social media Web sites to collect and analyze health-related data which could help identify outbreaks of infectious diseases and other public health and national security risks

  • Searching social media sources by geography

    Geofeedia, has created a group of algorithms that can search multiple social media sources by geography in real time; the postings, pictures, and tweets that show up in the results of a search are geolocation-enabled, are free, and results can be streamed on a mobile device, computer, or tablet. Businesses may have to pay a fee for more intensive searches

  • Supreme Court to hear police DNA-collection case

    The United States Supreme Court last week granted certiorari in Maryland v. King; in the case, Maryland law enforcement stands to lose the right to require a DNA collection as part of booking procedures for certain felony crimes; a similar law was passed by Congress in 2004 for federal arrests, and twenty-four other state legislatures have also passed such laws

  • New strategy for fingerprint visualization

    Identifying fingerprints on paper is a commonly used method in police forensic work, but it is not easy to make those fingerprints visible. Now, scientists have developed a new approach for making such fingerprints more readily readable

  • DHS grants help Kansas Law enforcement agencies buy new equipment

    DHS grants help local law enforcement agencies fight crime more effectively, but according to some, those same agencies are bypassing military grade surplus equipment for brand new shiny toys

  • Smart camera to describe what it sees -- and reason about what it cannot see

    Army scouts are commonly tasked with covertly entering uncontrolled areas, setting up a temporary observation post, and then performing persistent surveillance for twenty-four hours or longer; what if instead of sending scouts on high-risk missions the military could deploy taskable smart cameras? A truly “smart” camera would be able to describe with words everything it sees and reason about what it cannot see

  • Approaches to international consequence management for CBRNE incidents

    The National Research Council (NRC) of the National Academy of Sciences, through a grant sponsored by NIST’s Office of Law Enforcement Standards (OLES), is organizing an effort to understand the metrics and measures that are needed to develop standards of response that will support the basic capabilities of a country or region to respond to a chemical, biological, radiological, nuclear, or explosive (CBRNE) incident

  • Dutch law enforcement wants the authority to hack foreign computers

    The Dutch government plans to give Dutch law enforcement services the ability to hack into computers – not only in the Netherlands, but also those located in other countries – for the purpose of discovering and gathering evidence in cybercrime investigations

  • As domestic use of drones grows, privacy advocates worry

    Small aerial drones are moving from the battlefield to local communities, and the pace grows faster; during the next year, drones may be used in cities and towns to help fight crime and keep officers out of danger; their use would save on the cost of fuel for police helicopters; some would feel safer as a result, but activists worry that this could be the beginning of a systemic invasion of privacy

  • Worries about UAV use in both military and domestic missions exaggerated

    Dr. Steven P. Bucci, a Senior Fellow for Homeland Security & Defense Issues at the Heritage Foundation, talked with Derek Major, the Homeland Security News Wire’s executive editor, about the growing use of UAVs in both military and domestic law-enforcement missions; Bucci says that in targeting militants, American drone operators exercise a great deal of care to minimize, and eliminate if possible, death and injury to innocent civilians; he also says that the use of drones in domestic law-enforcement missions, if done properly, will not pose Big Brother risks, because drones may make surveillance easier and cheaper, but it will not give law-enforcement agencies any new authorities
