So because there are scary bad men out there the government should be able to do whatever the fuck it wants to be able to catch them? Even if that includes massively violating the privacy of every citizen (never know who's a scary bad man!!) in the country? Even if it includes building a massive database filled with who the fuck knows what that never, ever, gets erased? You know how they say the internet forgets nothing? This is even worse, since random fruit loops on the internet don't have access to your phone records, your banking records, your phone calls, your location and every niggling little detail of your entire life! If you think it's bad that /b/ can access something stupid you said on your blog and troll you even if you delete it, just wait until some scary bad men, I mean trusted public servants, get ahold of all that juicy personal information that those stalwart do-gooders of the NSA put together for them, they'll have a field day! Accidently piss off some bureaucrat at the DMV? He'll just call his cousin at the Ministry of Love and they'll whip up some charges doubleplusquick then off to the Re-education centers (actually, that's too expensive, off to the work camps, more than likely).
If you really think it's just "metadata" you're deluded. All this stuff that's coming out used to sound like the fever dreams of the loony fringe, and god damn does it suck having to listen to them smugly say "We told you so."
