Do you really think so?
Last time I checked, facebook made really really easy to investigate the live of everyone as never before. I'm not the one that says that, the FBI chief officers said that.
Last time I checked, there are cameras anywhere in the cities, from banks and shops to circulation plates readers with days of video buffers, so if something bad happens(terrorism) they have more information(and less cost) than ever before.
Last time I checked, they store your telephone tower triangulation information that stores when you were at what time.
They even can analogize all telephone communications of the entire country on real time, store them on a hard drive, and transcribe it for easy searching.
Today this people have more information than ever, but of course, they want more because they want to control everybody.
Terrorism and children protection has become the wild card they use to break the freedom of the people, convert us in the serves and making them the masters ( I got to meet the TSA people).
