The ability to do these things is spelled out in law, but my experience with the majority of people over the last several years is disbelief that it's being carried out on this scale or that it effects anyone but terrorists. You have no idea how many times I've been called a conspiracy theorist for telling people about these things, even when I put 2+2+2 right in their faces. Now it's no longer debatable. Those same people I was arguing with up to only a year ago are now as outraged as they should have been 10 years ago. That's kind of a big deal.
It's ridiculous they let this abomination like the PATRIOT Act survive this long anyways, with such little complaint. This isn't tin-foil hat stuff either. Thing is, it's true, nobody really cares. People suspected it in the USA, always. It's the entertainment media partially responsible for such a nonchalant response. The movies, TV, everything else has these story universes and themes where the US gov't is
1984 tier horrible, everything is monitored, listened to or read by at least 3 mysterious figures at a control terminal. People already know/ suspect their phone/ internet browsing history, whatever is being logged. Maybe not actually looked at. Maybe media has made people expect this, like they believe in erroneous things about war from hollywood. Pre-conditioned. It's made people paranoid and expecting the worst from the government, but not making them angry enough to protest either.
I think, this information is collected, but never looked at. They don't have the time or the people. They are working within the law that it only applies to terrorism and terrorism accessories. This PRISM shit has not likely effected anybody not a serious terrorist, I think the gov't is abiding by the law and Snowcone has not said anything contrary.
What I worry, is this kind of surveillance having a legal precedence, and some other future administration using it to horrible ends, with some other horseshit bill, set of crap freight-trained into law nobody in the USA agreed to. We have checks and balances, but we've seen politicians straining the constitution and the laws governing the government to their absolutes to push their agenda. Maybe PRISM is harmless now, but 20 years from now? 30? 40? Nope. This issue should have been brought up 10 years ago with the PATRIOT Act.
