I think the left's apathy was matched by the right's before when the right's guys were in power. In fact I have seen a near perfect correlation on this stuff and have been shocked by people who I was certain would be upset who are now making the same excuses the right made when the Patriot Act was first passed. "I have nothing to hide... it keeps us safe..."
I'm harping on this now like I did before because people are paying attention once again, but I need to shut up because my fanaticism about it is just becoming noise.
I think my first paranoia came in about 2002. I was working for an ad agency and we had bought a high end digital printing machine and it was having some color registration problems. We had the guy from the company come and repair and when it was recalibrated one of the graphic designers pulled out a loop to look at it and says, "Hey, I think it still has a problem, it is putting a yellow pattern over everything." Sure enough as we all looked through the loop there was a pattern you couldn't see with the naked eye, but was definitely there. He tinkered around for a while and couldn't get it to go away and finally called in for some help. He finally got someone who told him that the company would not comment on why there was a pattern being printed invisible to the eye.
Every other high end color digital printer (I haven't tried it on home versions of these) has done the same thing. We speculated it was so that the government could track for counterfeit money, but even when they got more sophisticated and wouldn't even let you scan money, the pattern remained.
Queue the dramatic music: Duhnn duhn duhnnnnnnnn.
But my point is this... whatever side of the aisle you favor, and even if you believe that these things are being used properly you should be concerned about the checks and balances managing these things. I personally don't believe they are adequate.
Framed another way, suppose you woke up one morning to find unmanned drones dotting the sky above you and the government said, "Don't worry, we are watching everybody equally with these, and if they see something suspicious then it gets put in front of a person who then will determine if it is a threat and then pursue warrants for more information.." Would you be alarmed or upset? Is what they are doing now really any different from that, and is our apathy because we can't see it?
