http://www.bloomberg.com/news/2011-...eeners-would-save-1-billion-mica-says-1-.html U.S. taxpayers could save $1 billion over five years if the 35 biggest U.S. airports used private rather than federal security screeners, said Representative John Mica, a Florida Republican. The conclusion is based on analysis by Mica’s staff of screening costs at Los Angeles and San Francisco international airports. Screeners at the privately staffed San Francisco airport on average checked 16,113 passengers each in 2010, compared with 9,765 for the government workers in Los Angeles, according to the report. “What we have are various layers of failure at great cost,” Mica said at a news conference today in Washington. “Managing a lot of people is not necessarily running a security operation.” The analysis extends a dispute between the House Republican majority and the Democratic administration of Barack Obama over the expansion of private screening in airports. John Pistole, who runs airport screening for Obama, froze the number of airports with private workers at 16 in January.
