DFW security is if nothing else inconsistent.

About two weeks ago, my wife was in line at the C21 security checkpoint. I was waiting for her to get through security before leaving when I noticed that a woman passenger already inside the secure zone opened the alarmed checkpoint exit door to the left of the checkpoint and let her friend through who was previously on a mobile phone in the queue waiting to get through the checkpoint. The two women were college aged, wearing clothing with Sorority/Greek letters and were giggling about their new found method of getting through the checkpoint without queuing.

I could not have been the only person to have seen this because an alarm sounded when the door was opened. However, a passenger made it to the secure zone without screening. When no one appeared to notice what just happened, I approached the ID checker and she just shrugged her shoulders and laughed. I walked past her to the first TSA agent I saw and let him know what I had seen. He too was indifferent and told he would look into it. I have the direct phone number of the TSA Director at DFW in my mobile phone (given to me after an extremely ugly incident in Terminal E a couple of months ago) so I called him and had to leave a message. I never heard back so I don't know what happened, but there was no terminal dump, no lock down and no heightened security alert of any kind as a result of this security breach. My wife's flight left on time and no one blew anything up.
