This is not about the "patriot pilot" or the gun that got past security. This is again about the pat-downs, but not about how they're invasive. This is about how they're failures.
Take a look.
Tammy Banovac reportedly had an "unusual contour on her buttocks" and was therefore not allowed to board the plane, but was allowed to sleep at the airport and try to get through security the next morning.
Think about this for a minute.
These procedures are supposed to prevent people from boarding the plane with bombs in their underpants. Another source I saw said that the TSA wouldn't allow her to strip to prove her innocence because TSA officers aren't authorized to conduct actual strip searches. So, with this "unusual contour" by her buttocks, she was allowed to stay at the airport, and the TSA was allowed to say "another plane saved!"
While if she had actually had a bomb in her pants, she could have just gone to the check-baggage line and blown it up, killing and injuring hundreds of people.
Even if it was PETN and difficult to explode, she could have gone into the bathroom and blown it up, killing people in the bathroom and causing a lot of damage to the airport.
Think about it. If this had been the actual "underpants bomber," they would have found an "unusual contour" at his groin, and because the explosives were sewn in there it's not like he could have just taken it out. The same thing woud have happened to him as would have happened to Banovac, and people would have still died, and it still would have been the TSA's fault.
Why do we have these policies if they don't even protect against the exact thing they're meant to protect against?
