  • Biometrics proves 1 percent of applicants to enter U.S. are unsuitable

    Chris Archer, the online content editor at IDGA (the Institute for Defense & Government Advancement), talked with James Loudermilk, Senior Level Technologist, FBI Science and Technology Branch, about biometrics and biometrics and homeland security; Loudermilk says that biometrics applications helped the FBI determine that about 1 percent of people who seek visa to visit the United States as tourists have previously done things that make them unsuitable guests; the conversation examines the application of biometrics for homeland security, issues relating to privacy and civil liberties, and what can be learned from international biometrics projects, including India’s UID scheme

  • Supreme Court deals near-fatal blow to Arizona SB 1070; states’ immigration efforts now in question

    In a major victory for the Obama administration, the U.S. Supreme Court yesterday struck down three of the four main provisions in Arizona’s tough SB 1070 immigration law, saying these provisions were pre-empted by federal law; the Court left in place the fourth provision – the one requiring Arizona local law enforcement during routine stops to check the immigration status of anyone they suspect is in the country illegally – but in reading the provision very narrowly, the Court left its implementation open to legal challenges on grounds that it violates racial profiling prohibition and other laws; in any event, the administration moved quickly to make that remaining provision meaningless by pulling back on a program known as 287(g), which allows the federal government to deputize local officials to make immigration-based arrests; the move means that even if local police step up immigration checks, they will have to rely on federal officials to make the arrests

  • Turf wars: math model shows crimes cluster on borders between rival gangs
