I blame poor training (and assorted reasons why some people delight in putting their hands on unwilling victims). TSOs have been taught to focus on breasts, breasts, crotches, breasts, buttocks, African-American hair, breasts, crotches.

All that groping of privates and now you tell us something might be on someone's back?

It's not fair. It's like a teacher asking a question on a test that wasn't covered in class!
