Morning Security Brief: UK Terrorism Arrests, UN Increasingly Using Private Security Contractors, Molecular Scanners, and More.

►Fourteen people have been arrested in the United Kingdom on suspicion of terrorism. Fox News reports that the individuals were arrested in "operations spanning several cities in the last week. Seven were detained by police across central England on July 3-5, six have been charged with preparing an alleged terrorist attack and one released without charge. In London, police arrested seven people on July 5-7—six are still being questioned, while a 30-year-old woman has been freed without charge. In addition to those 14, two Muslim men were arrested in late June — and later released without charge—after they were spotted canoeing on the River Lea, a branch of which runs through the Olympic site."

►A report published on Tuesday by the Global Policy Forum criticizes the United Nations for its increased use of private security and military providers. The Global Policy Forum believes that the use of private forces causes unaccountability and a loss of control. The report states that in 2010, the UN spent upwards of $70 million on private security and military contractors. ABC News has more on the story.

►Gizmodo reports on the impending use of molecular scanners by the U.S. Department of Homeland Security. By 2013, the site says,  "these portable, incredibly precise molecular-level scanning devices will be cascading lasers across your body as you walk [through] the airport and instantly reporting and storing a detailed breakdown of your person, in search of certain 'molecular tags.'" According to its manufacturer, the devices can detect a sugar-grain-sized piece of marijuana, the adrenaline levels within everyone's bodies, gunpowder residue, and more. The implications for personal privacy are vast and, the article states, largely unaddressed.

►A class-action suit against ABM Security Services has awarded security guards approximately $90 million for labor law violations. According to NBC-4 Southern California, "Security guards were required to remain on duty during break periods with their cell phones or pagers turned on, according to court papers about the case. But Superior Court Judge John Wiley ruled Friday that the policy did not give the guards legitimate rest breaks."
