im not trying to roast you, but i cant find any indication that TSA procedures, policies, or persons, have stopped any terrorist incident.
if you have, please share, as it looks like TSA in the present form is used for something other than transport safety, and duplicates many CBP functions.
I'm strongly in favor of massively de-scoping the TSA, but let's be real — if you could blow up a passenger plane by mailing a bomb, with no screening whatsoever, it would have been tried a few times. It's silly to discount the deterrent effect.
There are not terrorists lurking behind every door, but there are certainly disgruntled people who would do damage if there were no consequences or inhibitions.
