After recently taking a trip from Boston to Los Angeles, I can relate to the frustration people have with the TSA.
I found most of them to be rude. I opted out of the full body scanners at both airports (Logan and LAX). The experience in Boston was terrible. The TSA employees treat people that opt out like criminals. I had a better experience at LAX after expressing how bad I was treated in Boston. I understand that they are just doing their job but they really should throw a little compassion and manners training in with the job orientation.
