From August 2003 until May 2004, precise descriptions of the undercover personnel were provided to the screeners. The handing out of descriptions was then stopped, but until January 2005 screeners were still alerted whenever undercover operations were being undertaken. When no wrongdoing on the part of CAS was found, the contract was extended for four years. Some CAS and TSA workers received disciplinary action, but none were fired. A report on undercover operations conducted in October 2006 at Newark Liberty International Airport was leaked to the press. The screeners had failed 20 of 22 undercover security tests, missing numerous guns and bombs. The Government Accountability Office had previously pointed to repeated covert test failures by TSA personnel. Revealing the results of covert tests is against TSA policy, and the agency responded by initiating an internal probe to discover the source of the leak. In July 2007, the "Times Union" of Albany, New York reported that TSA screeners at Albany International Airport failed multiple covert security tests conducted by the TSA. Among them was a failure to detect a fake bomb. In December 2010, ABC News Houston reported in an article about a man who accidentally took a forgotten gun through airport security, that "the failure rate approaches 70 percent at some major airports". In June 2011 TSA fired 36 screeners at the Honolulu airport for regularly allowing bags through without being inspected. In May 2012, a report from the Department of Homeland Security Office of Inspector General stated that the TSA "does not have a complete understanding" of breaches at the nation's airports, with some hubs doing very little to fix or report security breaches. These findings will be presented to Congress. A 2015 investigation by the Homeland Security Inspector General revealed that undercover investigators were able to smuggle banned items through checkpoints in 95% of their attempts. Darrell Issa, chairman of the House Oversight and Government Reform Committee, and Rep. John Mica, chairman of the House Transportation and Infrastructure Committee, have had several joint hearings concerning the cost and benefits of the various safety programs including full body scanners, the Transportation Worker Identification Credential (TWIC), and the behavior detection program, among others. Some measures employed by the TSA have been accused of being ineffective and fostering a false sense of safety. This led security expert Bruce Schneier to coin the term "security theater" to describe those measures. Two studies by a group of Cornell University researchers have found that strict airport security has the unintended consequence of increasing road fatalities, as would-be air travelers decide to drive and are exposed to the far greater risk of dying in a car accident. In 2005, the researchers looked at the immediate aftermath of the attacks of September 11, 2001, and found that the change in passenger travel modes led to 242 added driving deaths per month.
