It's not out of context, they ARE strangers. And I agree, that would be an outrageous thing to say about the TSA officer based on the article alone.
However, at what point does this genital-touching patdown turn from uncomfortable to wrong? It's too quick to give a reasonable answer but that still doesn't discount what this could do to a child psychologically. The girl was crying. Sure she's a child but who the hell knows how that may manifest itself (or not) down the road in 10, 20 years?
Some child perverts don't go out and molest children. They join the TSA and get away with it. LOL but seriously, with all this TSA molesting bullshit in the news, is it hard to believe that perverts won't try and take advantage by signing up for a job?
