BOSTON ( MainStreet) -- What price security?For the Transportation Security Administration, it comes at nearly $8.1 billion a year, its budget for Fiscal Year 2011. The noble goal of keeping air travel safe from terrorist threat hasn't meant critics of the agency formed shortly after the attacks of Sept. 11, 2001, have been silenced. There are disgruntled travelers who rail against the "security theater" of taking off shoes and passing through X-ray machines. Airlines complain that they have suffered millions in lost customers and out-of-pocket expenses. Several airports are looking at the prospect of opting out of TSA agreements to pursue private security contractors that might save them money. A study by Cornell University even made the claim that traffic fatalities have risen since the hassle of air travel has pushed added motorists onto highways. But amid the gripes and cost to airports, airlines and taxpayers, there are some who profit from the threat of terrorism and the efforts of the TSA.
