Our Behavior Detection teams routinely -- and quietly -- identify problem people just through observable behavior cues. More than 150 people have been identified by our teams, turned over to law enforcement, and subsequently arrested... We publicize non-terrorist-related successes like a murder suspect caught in Minneapolis and a bank robber caught in Philadelphia.
One individual, identified by a TSO in late May and not allowed to fly, was killed in a police shoot-out five days later.
