You may not, but PLENTY of your colleagues do. I have personally witnessed them doing it, because they realize, as apparently you have not, that they suck at life and knowingly skrewed over other pilots. In fact one go jet pilot I'm personally familar with because we went to the same university, went to the trouble of changing out of his entire uniform before getting on the TSA crew bus to the TSA parking lot because it was closer to his pad. This of course ****ed me off to no end for a number of reasons. #1 I couldn't believe my university would create such an idiot. #2 I had just finished my last trip before getting furloughed because d-bags like him exist. And #3 there were no other TSA guys there to give him a ton of **** that he deserves. This same pilot also commutes, and of course dresses in street clothes, and runs to the back without checking in with the capt. Choosing to use non-rev passes instead of standard jump seating. He's actually a big enough a**hole to try and pull this off on TSA. This is the GJ pilot I most familar with, but I've seen PLENTY walking around the training center/airport with their ID's in their pocket or on backwards. The reason for this is simple. They know what they did was wrong, and they're ashamed of themselves, as you should be.
