  • Los Angeles County to cooperate with ICE on detaining undocumented immigrants

    The Los Angeles County Board of Supervisorsvoted Tuesday to extend 287(g), a program which allows federal immigration agents to train county jail employees to investigate whether certain inmates convicted of serious crimes are in the country illegally. Inmates confirmed as undocumented immigrants are then transferred to Immigration and Customs Enforcement(ICE) detention centers after serving their sentence.Aroud the country, at least 225 law enforcement agencies have decided to refuse hold requests from ICE.

  • California needs $54 million to deploy ShakeAlert earthquake warning system

    Officials in California need $54 million fully to implement the ShakeAlert earthquake warning system, according to a scientist with the U.S. Geological Survey (USGS).ShakeAlert detects earthquakes using the California Integrated Seismic Network of roughly 400 ground motion sensors which identify primary waves (P-waves) as they move through the Earth at almost twice the speed of the earthquakes’ destructive S-waves, which shake the ground.When an earthquake is detected, ShakeAlert informs emergency management officials of the quake’s epicenter, and a computer-generated voice counts the remaining time before shaking occurs.

  • A crime-fighting “magic” marker pen picks up hidden fingerprints

    A crime-fighting “magic” marker pen that can identify the hidden properties of receipts containing fingerprint deposits within a matter of seconds will be demonstrated at the Knowledge Transfer Network’s (KTN) Applications of Forensic Science Research and Development Technology Showcase 2014 event today (8 October) in London.

  • More law enforcement agencies refuse to hold undocumented inmates for ICE

    Recent court rulings have emboldened roughly 225 law enforcement agencies across the country to refuse requests from Immigration and Customs Enforcement(ICE) officials to hold undocumented inmates past their release dates so federal authorities can have time to deport them. Until recently, inmates suspected of being in the country illegally were held for an additional forty-eight hours until ICE agents arrived. Some municipalities began limiting the number of holds a few years ago, but several counties and cities have begun to ignore the requests all together after recent court rulings confirmed that the immigration holds are not mandatory.

  • U.S. Navy unveils autonomous swarmboats to “swarm” hostile vessels

    As autonomy and unmanned systems grow in importance for naval operations, officials at the Office of Naval Research (ONR) announced the other day a technological breakthrough that will allow any unmanned surface vehicle (USV) to not only protect Navy ships, but also, for the first time, autonomously “swarm” offensively on hostile vessels. The first-of-its-kind technology — successfully demonstrated over two weeks in August on the James River in Virginia — allows unmanned Navy vessels to overwhelm an adversary.

  • Mopping up toxic fire-fighting chemicals

    Australian scientists have come up with the solution to a world-wide pollution problem — how to mop up the toxic residues left after the use of special foams to fight fires. The technology uses a modified clay to soak up potential cancer-causing substances in the foam used by fire fighters, defense facilities, and airports worldwide to suppress fires.

  • U.S. Cyber Command plans to recruit 6,000 cyber professionals, as U.S. mulls offensive cyber strategy

    Last Wednesday, House Intelligence Committee Chairman Mike Rogers (R- Michigan) told reporters that he would like to see the United States adopt a more offensive strategy in cyberspace, but added that the Pentagon, intelligence agencies, and law enforcement must first develop protocols for offensive cyber measures.The following day, U.S. Cyber Command (USCYBERCOM) announced plans to recruit 6,000 cyber professionals and create 133 teams across the country to support the Pentagon in defending the nation’s cyber infrastructure.

  • The Big One will have frightening consequences for Los Angeles: Scientists

    Scientists cannot accurately predict when California’s next massive earthquake – or, the Big One – will strike, but they can predict the effects, and it is frightening. Scientists with the U.S. Geological Survey (USGS) say these effects will include powerless rescue services, widespread fire damage, and no fresh water for months on end. The 1994 Northridge Earthquake was the region’s the last mega-quake, but scientists say that “When we have the San Andreas earthquake, that earth fault will probably be about 20 to 30 times larger than the fault that produced the Northridge earthquake [which still resulted in $20 Billion in damages].”

  • New cyber initiative to put Israel’s Beer-Sheva region on the world’s cyber map

    Ben-Gurion University of the Negev is a central component of the new CyberSpark initiative, an ecosystem with all the components which will allow it to attain a position of global leadership in the cyber field. The CyberSpark initiative is the only complex of its type in the world – a government-academic-industry partnership which includes Fortune 500 companies and cyber-incubators, academic researchers and educational facilities, as well as national government and security agencies. The CyberSpark Industry Initiative will serve as a coordinating body for joint cyber industry activities with government agencies, the Israel Defense Force (IDF), and academia.

  • Nanoparticles will allow detecting previously undetectable fingermarks

    A group of researchers from Switzerland has thrown light on the precise mechanisms responsible for the impressive ability of nanoparticles to detect fingermarks left at crime scenes. The researchers have provided evidence contesting the commonly accepted theory that nanoparticles are attracted to fingermarks electrostatically. The attraction, they claim, is in fact chemical and is caused by compounds on the surface of nanoparticles bonding with a complex cocktail of compounds present in fingermark residue.

  • Experts urge caution in relying upon eyewitness identifications in criminal cases

    A new report from the National Research Council recommends best practices that law enforcement agencies and courts should follow to improve the likelihood that eyewitness identifications used in criminal cases will be accurate. Science has provided an increasingly clear picture of the inherent limits in human visual perception and memory that can lead to errors, as well as the ways unintentional cues during law enforcement processes can compromise eyewitness identifications, the report says.

  • Transparent nanoscintillators for radiation detection in homeland security, medical safety

    Researchers say recently identified radiation detection properties of a light-emitting nanostructure built in their lab could open doors for homeland security and medical advances. The researchers describe a new method to fabricate transparent nanoscintillators by heating nanoparticles composed of lanthanum, yttrium and oxygen until a transparent ceramic is formed. A scintillator refers to a material that glows in response to radiation.

  • In U.S. criminal courts, non-citizens face harsher sentencing than citizens

    Non-Americans in the U.S. federal court system are more likely to be sentenced to prison and for longer terms compared to U.S. citizens, according to a new study. The researchers analyzed U.S. federal district court data from 1992 to 2008 for this study. In 2008, for example, 96 percent of convicted non-citizens received a prison sentence, compared to 85 percent of U.S. citizens. The researchers said that the issue of punishment disparities between citizens and non-citizens is a growing concern as the number of non-citizens in the United States — estimated at more than twenty-two million — continues to grow.

  • Law enforcement agencies use technology to compensate for shrinking budgets

    With funding shrinking in many sectors of law enforcement, agencies are searching for new ways to operate affordably while maintaining quality standards.Police departments’ budgets quadrupled between 1982 and 2006. With federal budgets shrining, there are simply too many challenges which would not allow for police budgeting-as-usual.

  • Assad retains secret caches of chemical weapons: Israeli intelligence

    Despite committing to dismantle and give up its chemical weapons – Syria was in possession of the world’s largest chemical weapons stock — President Bashar al-Assad’s regime still maintains a “residual” chemical weapons capacity, consisting of a few tons of the proscribed materials. Israel’s intelligence community has concluded that the Assad regime has decided to keep this reduced, but still formidable, chemical weapons capability, and has successfully concealed it from the inspectors of the UN chemical weapons watchdog who, a few weeks ago, have declared the chemical disarmament of Syria to be officially complete. Israeli defense officials believe that these sarin gas weapons would likely be deployed if the Assad regime faced an imminent threat to its survival. The Syrian regime is continuing to use chemical weapons which were not covered by the U.S.-Russian chemical weapons disarmament agreement, especially chlorine gas.
