How can a federal transportation security officer’s thought process influence baggage screening decisions? The Transportation Security Administration and Sandia Research Laboratories are investigating the impacts on threat detection when officers are asked to switch between TSA Pre-Check and standard passenger lanes.

TSA's VIPR squads have been patrolling railway stations, sporting events, rodeos, highway weigh stations and more, but not all parties are pleased about the group's expansion.

There was a 26 percent increase in TSA employee misconduct between 2010 and 2012, a new report from the Government Accountability Office says. 

The behavioral detection screening program has 2,800 employees and no comprehensive training program, leaving many in Washington to wonder whether the program should be expanded.
