Appleblossom, I don't understand how you can fault the parents when TSA fails to make it clear that genital and breast touching will be part of patdowns. What if the parents had no idea their daughter could have been subjected to a sexual assault patdown? It's clear that once the gravity of the situation hit home, they cared enough about their daughter to drive her home from Florida.
Believe it or not, there are still people in this country who have no idea that anything's changed at airport security since 2009 - and that's intentional on the part of TSA. TSA can't admit to themselves and won't admit to us that they are putting their hands on people's sexual organs.
