I am surprised that there hasn't been more in the way of complaints and protests. Most people seem pretty blasé about the surveillance and information gathering. This might be because 'Joe Soap' feels he is just an average, peaceful citizen and therefore has nothing to worry about... however consider that you might have nothing to worry about today, but what if some time down the road you decide to join a gay rights group and protest about a particular issue... if you then start to look like a trouble maker the information needed to destroy you would have already been collected.
So the next question becomes do you trust the current government not to abuse the information they are collecting? Even if you do, will you trust the next government, maybe a Republican government? You might get to the point where you wouldn't protest about anything, just to be safe.
The main justification seems to be the 'war on terror', however it seems to me that terrorists would be well able to encrypt data and find ways to evade government surveillance, such that the only people really being spied on are peaceful citizens, who would not bother evading surveillance.
"Information is power", and with so much in depth information we can only conclude that the government already has far too much power.
I, for one, would be much more nervous about getting involved in any form of activism today, that I would have been say in the seventies. It's a sad thought... it's like we are starting to move backwards, not forwards, in terms of some of the most basic rights.
