What's Wrong? Don't You Trust Us?

"Oh, no you won't" is the reaction of cops and other first responders to an almost rude FBI decision to ask its Joint Terrorism Task Force members to take a lie detector test. To the FBI, it's a smart move: Since 9/11, the task force of federal and local officials has expanded to some 1,500 in over a hundred offices nationwide. But to some members it's a slap, and something that could hurt their careers if the polygraph—whose accuracy is widely questioned by scientists—burps out an error. Joining local cops in opposition are agents with the Homeland Security Department's Immigration and Customs Enforcement.
