I've read a few thousand posts in my time here on TS/S that state, either directly or implied, that if only TSA was disbanded/abolished/go back in time and prevent then we would be able to save the Constitution. My question is- what parts of the TSA's mission and/or actions are unconstitutional.

Be specific as to what about the TSA is offensive (legally speaking, that is) and what parts of the Constitution are affected.

Incidentally, this is a serious question in case there's any doubt.
