Unfortunately every group has those that do things that make you shake your head. Those who claim to be Libertarians are no different in that regard. However, it's not a good idea to make claims when there are video cameras out there that can tell the whole story:
This Libertarian Radio Host Lied About TSA Harassment. What I find interesting is that the TSA released the video in response to the accusations, it's not something they normally do. If the video had sound, it would be a much better indication of exactly what took place.
After watching both videos, I find it hard to agree with the few out there that claim the video shows she was handcuffed, though it does appear that particular airport has too many TSA employees for them to stand around with nothing to do.
