  • Emergency communicationWashington State county considering levy to fund new emergency-radio network

    Voters in King County, Washington, which includes Seattle, will be asked in a special 28 April election to approve a levy for a new emergency-radio network to expand coverage throughout the county and replace outdated equipment used by police, fire, medical, and other emergency personnel. The levywould raise $246 million over nine years and cost $0.07 per $1,000 of assessed property valuation beginning in 2016. The levy proposed would increase the number of transmission towers from twenty-six to forty-six and replace 19,000 radios and 117 dispatch consoles.

  • SurveillancePolice use of Stingray technology raises privacy advocates’ ire

    Detective Emmanuel Cabreja, a member of the Baltimore Police Department’s Advanced Technical Team, recently testified that the unit owns and operates a Hailstorm cell site simulator, the latest version of the Stingray — a device which mimics a cellphone tower to force phones within its range to connect. For years, law enforcement agencies have used Stingrays to find wanted suspects, but until recently, the technology was largely unknown to the public, partly because law enforcement officers were banned from revealing such information to judges and defense attorneys.

  • License plate readersAs law enforcement increases use of license plate readers, privacy advocates fret

    Law enforcement agencies across the country have adopted license plate readers (LPRs) to monitor vehicles driving on roads and to locate wanted suspects or suspended drivers.After canceling plans last year to operate its own LPR database, DHS announced last week, through a bid request, that the agency’s ICE is seeking a private sector firm to provide access to already functioning LPR databases for a subscription fee.Privacy advocates argue that the gains made with LPR systems, do not justify the mass monitoring of Americans who drive.

  • SurveillanceDHS seeking license plate readers (LPRs) technology -- again

    A year after privacy concerns led DHS to recall its solicitation for bids by private companies to help the department create a national license-plate database which would allow unlimited access to information obtained from commercial and law enforcement license plate readers (LPRs), the agency has renewed its solicitation on the basis that privacy concerns raised by civil liberties groups and lawmakers could be addressed and managed.

  • Patriot ActPrivacy concerns potentially an obstacle to 1 June Patriot Act reauthorization

    With the USA Patriot Act set to expire on 1 June, lawmakers are debating whether the bill, which allows the National Security Agency (NSA) to collect bulk metadata of U.S. phone records, should be extended. The act was last renewed in 2011, before former NSA contractor Edward Snowden revealed details of the U.S. intelligence agency’s surveillance activities. The debate around the reauthorization of the Patriot Act focuses on Section 215 of the law, used by the NSA to mass collect phone records in an effort to locate terrorists who might be calling supporters in the United States.

  • SurveillanceJustice Department takes first step toward expansion of search warrants’ reach

    The Justice Department has taken a first step toward allowing judges to grant warrants for remote searches of computers located outside their district, or when the location is unknown. On Monday, the Judicial Conference Advisory Committee on Criminal Rules approved an amendment to Rule 41 by an 11-1 vote. The existing provision allows judges to approve search warrants only for material within the geographic bounds of their judicial district, but the FBI has said it needs the rule updated to address the increasingly complex digital realities of modern day.

  • ForensicsRecovering obliterated serial numbers in metals

    Law enforcement agencies use serial numbers to track ownership of firearms and build criminal cases. Serial numbers, however, can be removed by scratching, grinding or other methods. Analysts typically try to restore the numbers with acid or electrolytic etching or polishing, because deformed areas behave differently from undamaged material. These methods, however, do not always work. Researchers have now demonstrated a technique for mapping deformation in metals that can recover destroyed serial numbers on metal objects such as firearms, a common challenge in forensics.

  • ForensicsFrench experts rule out foul play in 2004 death of Yasser Arafat

    A French prosecutor yesterday announced that French medical and forensic experts have ruled out poisoning as the cause of the 2004 death of Palestinian leader Yasser Arafat. The prosecutor of the western Paris suburb of Nanterre said the experts, following a thorough examination, found there was no foul play in Arafat’s death. The findings by the French experts are identical to findings by a different French team and to the findings of Russian experts. A Swiss team, however, initially said that their test results of personal affects left behind by Arafat led them to conclude that radioactive poisoning was “more consistent” as an explanation of Arafat’s death.

  • Nuclear forensicsNuclear forensics to the aid of nuclear detectives

    Fans of the popular TV series “CSI” know that the forensics experts who investigate crime scenes are looking for answers to three key questions: “Who did it; how did they do it; and can we stop them from doing it again?” The field of nuclear forensics has similar goals and uses similar techniques — but with even higher stakes. “In nuclear forensics, we want to know first, is someone able to put together the parts to make a nuclear weapon and set it off?” says one researcher. “And second, if one is set off, can we find out who did it, how they did it and are they going to do it again? Like traditional forensics, we’re looking for nuclear signatures, just like fingerprints; we’re looking for the technological and material clues and evidence to tell us what somebody had done to make this unfortunate thing happen.”

  • Patriot ActClapper: Congress would be blamed if Section 215 is not renewed -- and “untoward incident” occurred

    James Clapper, the director of national intelligence, said that if Congress failed to reauthorize a controversial provision of the Patriot Act by June, then lawmakers who opposed the renewal of the provision – Section215 – would bear the blame if a terrorist attack, which could have been prevented by actions Section 215 permits, happened. Clapper said that if Congress decided not to renew the Patriot Act, or decided to renew it without Section 215, and an “untoward incident” occurred as a result, he hopes “everyone involved in that decision assumes responsibility” and does not just blame the intelligence community.

  • SurveillanceFISA court reauthorizes NSA’s bulk metadata collection until 1 June

    More than a year after President Barack Obama announced that he will work with Congress to curb the National Security Agency’s (NSA) dragnet surveillance program which collects large amounts of U.S. phone metadata, the Foreign Intelligence Surveillance Court approved last week a government request to continue allowing the agency to operate its bulk data collection until 1 June, when the legal authority for the program is set to expire. The required reauthorization of the program every ninety days has already been granted four other times — March, June, September, December — since Obama made his announcement in January 2014.

  • SurveillanceKouachi intelligence failure: The struggle to balance security, privacy, budgetary concerns

    About seven months before the attacks on the Paris office of Charlie Hebdo, French domestic intelligence agency monitored Saïd Kouachi for at least two years, and his younger brother Chérif Kouachi for at least a year. The surveillance of both brothers had led nowhere, and was later considered a non-priority for intelligence officials. The Kouachi brothers did not appear to be an imminent threat, and it would have taken twenty-five agents to monitor the two brothers around the clock. Experts say that the failures and missteps by French law enforcement in the Kouachi case should be a lesson to other Western governments which may have relaxed surveillance practices targeted at would-be terrorists in order to comply with budget cuts or out of genuine concern for civil liberties.

  • CrimeHair dye “CSI” could help police solve crimes

    Criminals with a penchant for dyeing their hair could soon pay for their vanity, as scientists have found a way to analyze hair samples at crime scenes to rapidly determine whether it was colored and what brand of dye was used. Researchers showed that surface-enhanced Raman spectroscopy (SERS) could be used rapidly to confirm whether hair samples, even microscopic ones, were dyed and what brand of colorant was used.

  • Rail securityRailway stations should adopt some of the security strategies deployed by airports: Experts

    A 2013 study by the U.K. Home Officerecorded crime rates across every postcode in England, Wales, and Northern Ireland, and found that four of the top ten U.K. crime hot spots are major railway stations. Railway stations experience large volume of crime due to their highly congested environments, which gives pickpockets and thieves opportunities to find a target. Large stations are also introducing more retail outlets, which increases the likelihood of more shoplifting offenses. Experts note that airports have many of those same characteristics, but they fare far better in crime rates. These experts argue that rail stations should adopt some of the strategies deployed by airports around the world.
