Devil's advocate, here: As long as it's restricted to terrorism investigations I don't care. If it stops bombs from going off go ahead and snoop through Facebook's database, big deal. If it ever trickles down to DEA or local police then it's a problem. If secret courts and SQL dumps become standard procedure then everything falls apart. If this is considered constitutional I don't know how you're going to tell Officer Shitforbrains he can't look at your phone records and Google search history to find out where you bought that joint.
