The first thing that comes to my mind is the whole Snowden series of events. Spying every citizen, is wrong. Also, I'm seeing the effects of something similar in my country, where this sort of spying is used to curb free speech, dissent, and completely kill the very essence of democracy.

It is wrong, and there has to be better ways. I don't remember the exact procedure, but NSA didn't need much clearance to spy on any American citizen.
