Surprise?

Am I not the only one who found this:
US Discovers Violations in Surveillance Program
Surprising?
Really - did any of us expect that the NSA would follow guidelines? I'm sure they were doing a range of things - from listening to their former girlfriends/wives conversations to, the well documented, spying on a Congressman making a trip to the Middle East.
Didn't they just hook up their hose to AT&T and try to trap a copy. The sheer volume of data makes the computing power they'd need to sort/pull/find specific bits of data mind-boggling - and yet them seem to have managed to do it. Impressive & terrible all at once. Can't we put this nonsense to a stop?
