This. Also TSA people can be huge jerks if you don't do what they tell you to sometimes. It's the same as when a teacher or parent tells you something, they're authority and they're supposed to know what they're doing, and we're supposed to trust them. Doctors are the same. It's pretty much solely the TSA person's fault for ignoring the doctor's note or at least not taking it to a higher authority.
Buuuut that's their job and it's a tough one. They have to make tough calls every day that could put them on the spot, but in their eyes it's better than being the dude who let an honestly dangerous person on board. At least the girl was compensated.
