I think they've just increased the "random" pat downs since 12/25. I flew out of ORD on 1/11, terminal 3. I got selected for a "random" pat down, my first one. It was early and the checkpoint was not busy. Both TSA people doing pat downs were women so they were selecting nearly every woman that went through. The kicker was she only patted me down from mid-thigh down to my feet for a total of about 5 seconds. I'm NOT complaining mind you, I don't wish for a more thorough massage, but there really was no point in it. It's all for show.
