They could have sent up a couple of guys in a Crown Vic with donuts and coffee and gotten better intel. Instead, they send up an army and come back with nothing.
They were given all this crap, and now they have to justify having it. So since there are not a lot of actual terrorists, they will use SWAT teams for parking tickets.
It will then become a self fulfilling prophecy, because people will only put up with this kind of thing for so long before they start pushing back. And they will be branded terrorists just for disagreeing.
