When the US got hurt on 9-11, it was scared and angry, and did some things that we're starting to regret. Among those things was to write laws that basically increased the powers granted to out national security apparatus.
There's a misconception that all of this latest scandal was a vast secret plot. It wasn't, but a lot of people seem not to have been paying attention. It was done, for the most part, right out in the open, by a government that was responding to our collective will. That's an important phrase, "collective will". I might not agree with it, and you might not, but the majority carried the day, and that's how it's supposed to work. Of course, we can change out minds, and that seems to be the trend now.
The thing that I find most pathetic in all of this is the vilification of the people who've been carrying out our collective will in good faith. There's no justification for that. Yes, some might not be the brightest or most noble people, but disagreeing with something doesn't grant superiority. We've stopped spitting on soldiers, even when we disagree with the war. If we don't like the system we've got, it's up to us to change it.
