I wager that, for the average American, this news made them feel safer, and the only thing they're upset about is that the "bad guys" now know something they shouldn't.
I'm convinced most of us Americans just don't care, and that bothers me more than what the government is doing.
If it's government running amok, that leaves open the possibility that they can be reigned in. All you need to do is get the people sufficiently aware and sufficiently angry and the problem is solved!
But if it's simply the government obeying the will of the people, then we're screwed much harder. Convincing people who are deeply afraid of terror attacks and who find comfort in massive government programs meant to protect them that they should invert their priorities is massively difficult, perhaps impossible.
