This kind of proof requires use of your brain.
We've all heard the reasoning the government uses to justify their extensive surveillance and intel networks. They say "It is for the public good, to keep the public safe from enemies foriegn and domestic".
Well, what kind of info are they gathering and storing forever? All internet and phone data, gps tracking, drone and satellite imagery, millions of video surveillance devices in businesses and homes, as well as millions of traffic video cams and other city surveillance.
So, they've set up an excellent system to catch terrorists...like your neighborhood oathkeeper, homeschooler, christian, patriot...and the islamic terrorists. Right?
So, since this system is so massive and contains basically all the information needed to catch perps and keep us safe, we should be hearing about more and more arrests of child abductors, murderers, rapists, etc...right? Every time we hear about a new abduction or murder -- or terrorist bombing -- we should expect the perp to be arrested and the child found in a matter of hours to days. Not weeks. Not months. Not years. And almost never "unsolved". Right?
Since we as citizens clearly do not see those kinds of results, I don't think we're seeing the correct bang-for-buck ratio with this surveillance system we paid for.
It also proves that the government doesn't give a shit about us, and that they have been covering for murderers, pedophiles, rapists...letting children be taken from their parents and be sexually assaulted and murdered, or kidnapped and abused for years, etc. With their all too untimely discovery of who blew up that apparent surveillance deadzone at the finish line at the boston marathon, plus the abilities their systems give them, it is clear we were being lied to about when they knew who did it and that they were being "sought" (they clearly knew where they were the whole time with this system).
In conclusion, the government is guilty of not only Constitutional violations through the use of this system, but they are also covering up murders and kidnappings in order to not expose the reach of their system, and they are at the very least derelict in their duties. QED.
Suck it NSA fascists.
