This is pretty incredible. Why are they doing this? Even if there's a bomb in a parked car, does it really pose a safety threat? Who is going to bomb an empty valet parking lot?
Obviously the answer is "because they can". There is no grounds for suspicion, just their assumption that they might find some kind of contraband, etc.. This is 100% pure inexcusable overreach.
The only goal of the TSA is to prevent attacks and find busy work related to this. With such a goal, they try to find as many ways to search as possible.
Perhaps a better solution(which doesn't violate the constitution) would be to just not leave them near the terminal for a short duration...
Their solution doesn't even seem to address the security issue (such as it is). Presumably when the car is left near the terminal for a short duration it's because the valet doesn't have time to attend to it. Doesn't this mean that the search wouldn't happen until after it's been parked up? If they do search it first couldn't they just use the time to move it somewhere where it doesn't pose a risk(presumably they do the kind of thorough search that could detect a bomb right??). The whole thing wreaks of vapid measures designed to further some other agenda (I won't speculate on what exactly this might be).
