Sure it was the BP or the ID?
Phoenix was one of the first airports to change the ID checker from outside person to a TSA person. You also have to remove the ID from a holder, and they shine the flash light at the ID to see the Hologram (making sure it's not fake).
One time I asked the ID checker if he has spotted a fake ID, and he said "not yet, but if I don't do it on EVERYONE, I will get in trouble."
