You can't prove a thing. That's the thing. She could be a publicity hound for all anyone knows.
Even if it is true, the TSA is filled with a large number of people, many of whom are poorly paid functionaries. Think of any major metro police force. You could fill a book with the buffoonery in any one of them. Think of how many weird NJPs and courts martial happen on any base over a period of time. Every single adverse incident involving the TSA gets major media coverage, because it fits a stock storyline. I'm not saying that such events should be tolerated, but some will treat anything as an indictment of the TSA as a whole. We hold our Sailors and Marines up as the greatest people in America, yet if every instance of our employee malfeasance was publicized, Americans would start to wonder what kind of assclowns are defending them.
