This is such bullshit on so many levels I just can't stand it.
They record EVERYTHING but only look at the metadata. But when the metadata looks interesting, they can tie it to the message, which, curiously enough, they have already so they don't have to ask permission to look for it. They have J. Edgar Hoover files on the entire fucking country at their disposal.
Ahh... but it's legal; the FISC said they could do it. I believe that the Oxford dictionary definition of the FISC involves kangaroos and rubber stamps, but that's a different topic. After all, OUR representatives (the ones we voted for even if they were rotters, because the other ones were such bad guys)passed laws contravening the constitution of the country allowing them to do so. This was, of course, highly necessary since the odds of the average citizen being killed by a terrierist (or schnauserist) is slightly less then them winning money from the lottery. As long as power can pass laws to legitimize their actions, they can do no wrong. It's like if the mafia could buy congress critters, they could operate openly... wait... never mind. Moving on...
You have, in the past, been on my ass about being a purity troll. You may have a point, but when people who are supposed to be representing me totally trounce major values I support, I get a little pissy. This support of endemic surveillance and authoritarian government is a little pushy in the other direction. If our national security will not allow for individual freedom and liberty, then it is no longer useful.
