If you have injured yourself in any way (for me, it was skiing) TSA at the Denver airport (DIA) will consider it suspicious behavior. I thank the gentleman who was doing the scanning and told me that I did not have to get scanned, but to the female TSA agent named Linda who barked orders at me and had a HUGE attitude that I wasn't getting scanned, you can go suck it. There was a reason I was in the metal dectector line, a reason why I was holding my arm to my side, and a reason why I was taking so long taking off my layers of clothing and only using one arm. My family is in the airline industry and they've had more background checks than you, ma'am, so get over yourself, you waste of federal money, overrated rent-a-cop.
