It is feasible to put a bomb up one's rearend. After the first terrorist does that, will we all have to undergo full body cavity searches to board a plane? That has been the pattern of TSA.
Once it is established that it is OK to do this to board a plane, what happens after the terrorists attack a mall or some other place in the US. Will these searches be extended to having to undergo one to enter Wal-Mart, or Joe's Corner Hardware in downtown Podunk? We will have said it is OK!
I am sorry, but the Terrorists have already won. We are spending trillions of dollars, screwing up our economy to do this. And, I do NOT have any better response to them.
They have won, as their stated goal was to screw up the US economy. And, they have for the foreseable future.
