So I'm watching this new show "Almost Human." its about a future where technology destroys the traditional CSI techniques (e.g. DNA bombs to wipe out DNA evidence), and police are "forced to respond" with synthetic human police. So you have a cop that can go into a business and just download all the documents on their network without touching anything. At one point the synthetic cop asks his human partner "we don't need a warrant for this?" And the partner is like "I didn't think so either." The point of the joke is that the robot wants to follow the warrant requirement, because its a rule, but the human cop knows that its okay to break the rules when the bad guy could get away.

So no, not everyone opposes mass surveillance. Just watch some movies. Since the time of westerns there's been this deep seated idea that procedural protections are optional when a bad guy could get away. This is not a failure of democracy. This is a non-democratically designed procedure being eroded by democracy.
