TSA pat-downs – security gone too far?

Posted Nov. 22, 2010, at 1:44 p.m.

The new Transportation Security Administration’s airline protocols that have passengers in many airports having to pass through full-body scanners and also, at times, being subjected to pat-downs have many Americans believing the TSA has gone too far. Yet

surveys show that 80 percent of Americans support the new policies.

Are these policies necessary? Is there a better way to screen for someone who is willing to, say, put a bomb in his underwear? What if a would-be terrorist hides an explosive device in a body cavity? Should these also be subjected to search on reasonable suspicion? How far is too far?
