Gotcha.

Yeah, it's inefficient. Still... I mean let's stick with ocean analogies. There are [i]not a whole lot[/i] of shark attacks in a given year -- but we still try to protect ocean-goers from sharks. If the lifeguard blows that shark-whistle (do they have shark whistles? Shark alarms? Shark cowbells, I bet it's cowbells). If the lifeguard rings that shark-cowbell, you get your butt out of the damn water. 

I think the government [i]has to be[/i] a little paranoid -- it's their job. NSA phone monitoring is a LOT paranoid, and it's probably a violation of civil liberties, and I'd like it to stop. Browsing facebook is a happier medium, and like I said I'm still not crazy about it -- but I understand why it's happening, and they're not literally insane for thinking it up.
