• RADIATION DETECTIONA New Way to Detect Radiation Involving Cheap Ceramics

    By Elizabeth A. Thomson

    The radiation detectors used today for applications like inspecting cargo ships for smuggled nuclear materials are expensive and cannot operate in harsh environments, among other disadvantages. Work by MIT engineers could lead to plethora of new applications, including better detectors for nuclear materials at ports.

  • LAW-ENFORCEMENT TECHNOLOGYCops Running DNA-Manufactured Faces Through Face Recognition Is a Tornado of Bad Ideas

    By Paige Collings and Matthew Guariglia

    In keeping with law enforcement’s grand tradition of taking antiquated, invasive, and oppressive technologies, making them digital, and then calling it innovation, police in the U.S. recently combined two existing dystopian technologies in a brand new way to violate civil liberties.

    By Christoph Schmon

    In a milestone judgment—Podchasov v. Russia—the European Court of Human Rights (ECtHR) has ruled that weakening of encryption can lead to general and indiscriminate surveillance of the communications of all users and violates the human right to privacy.

  • SEEING AROUND OSTACLESScience Fiction Meets Reality: New Technique Overcome Obstructed Views

    By Cassidy Delamarter

    Using a single photograph, researchers created an algorithm that computes highly accurate, full-color three-dimensional reconstructions of areas behind obstacles – a concept that can not only help prevent car crashes, but help law enforcement experts in hostage situations, search-and-rescue and strategic military efforts.

  • MARITIME SECURITYCharting the Future of Maritime Security

    The United States is a maritime nation surrounded by 95,000 miles of shoreline. Changes in economics, geopolitics, society, demography, or other factors, pose varied and evolving threats to the country’s maritime space – its waterways, ports of entry, and coastline borders.

  • CRIMINAL JUSTICEPolice Departments Are Turning to AI to Sift Through Millions of Hours of Unreviewed Body-Cam Footage

    By Umar Farooq

    Body camera video equivalent to 25 million copies of “Barbie” is collected but rarely reviewed. Some cities are looking to new technology to examine this stockpile of footage to identify problematic officers and patterns of behavior.

  • POLICEHow Chicago Became an Unlikely Leader in Body-Camera Transparency

    By Eric Umansky

    The city has a long history of brutal, violent policing, but its latest approach to body-worn cameras and police oversight could serve as a national model.

  • TERRORISMThe Hidden Cost of Being Branded a Terrorist by the U.S. Government

    By Masood Farivar

    The FBI credits its Terror Watchlist with keeping the country safe, but critics point to the experience of thousands of innocent American Muslims who were swept up by a screening system, and then found themselves trapped in a Kafkaesque nightmare as they tried to clear their names. The watchlist currently contains nearly two million names, of which about 15,000 are U.S. citizens and permanent residents.

  • DETECTIONLeveraging Artificial Intelligence in Explosives, Narcotic Detection

    DHS S&T is applying emerging technologies in the development of artificial intelligence / machine learning technologies – and searching for ways to use these technologies to identify dangerous compounds, like those found in explosives and narcotics.

  • PRIVACYUtah Supreme Court Upholds Right to Refuse to Tell Cops Your Passcode

    By Andrew Crocker

    The Utah Supreme Court ruled that prosecutors violated a defendant’s Fifth Amendment privilege against self-incrimination when they presented testimony about his refusal to give police the passcode to his cell phone. The Utah court’s opinion is the latest in a thicket of state supreme court opinions dealing with whether law enforcement agents can compel suspects to disclose or enter their passwords.

  • TECHNOLOYWhat if Law Enforcement Could ‘See’ Through Walls?

    New technology allows law enforcement to easily and safely identify whether any individuals are inside a room when direct line-of-sight is not an option. This is especially critical when conducting breaching operations, searching for trafficked individuals or in potential hostage situations, where the device gives responders precious intelligence and situational awareness while reducing the risk of physical harm to themselves.

  • RADIOLOGICAL RESPONSEPreparing U.S., Partners for Radiological Response

    By Paul Menser

    After the September 11th attacks, security professionals worried that terrorists might detonate a “dirty bomb” – an explosive device enhanced with radiological source materials. Responders for this type of event had to be trained.

  • PRIVACYEFF to Supreme Court: Fifth Amendment Protects People from Being Forced to Enter or Hand Over Cell Phone Passcodes to the Police

    The Electronic Frontier Foundation (EFF) last week asked the Supreme Court to overturn a ruling undermining Fifth Amendment protections against self-incrimination and find that constitutional safeguards prevent police from forcing people to provide or use passcodes for their cell phones so officers can access the tremendous amount of private information on phones.

  • FORENSICSForensic Science Method for Firearm Identification Is Flawed

    Like fingerprints, a firearm’s discarded shell casings have unique markings. This allows forensic experts to compare casings from a crime scene with those from a suspect’s gun. Finding and reporting a mismatch can help free the innocent, just as a match can incriminate the guilty. But a new study reveals mismatches are more likely than matches to be reported as “inconclusive” in cartridge-case comparisons.

  • CROSS-BORDER THREATSStriving for a More Secure World

    By Allan Brettman

    PNNL experts work with international partners to tackle cross-border biological and chemical threats. PNNL’s border security focus can be traced to the breakup of the Soviet Union in the early 1990s. U.S. policy makers became concerned about the security of nuclear material in the newly independent states of the former U.S.S.R.
