Quick hit:
I think the reason most Americans don’t seem to care about the massive secret agency info-suck is the same reason most Americans don’t seem to care about the massive numbers of us imprisoned for long periods of time in inhumane conditions.
Actually, two, related reasons. One, we don’t think “we” are at any risk of having info used against us/imprisonment and thus don’t feel any sympathy for or solidarity with “them”, who are justly targeted.
Two, we punish legislators who are “soft on crime/terrorism”, not those who are harsh—again, because those legislators are protecting “us” against “them”.
At its worst, this kind of thinking means that any questions of responses to crime/terrorism opens the question-er to intimations that she might not be one of “us”, not to be trusted, and, perhaps, should come under the same type of treatment as “them”.
Damned effective at keeping “us” in line.
