Again, I'm going to absolutely disagree with that.

First of all, I have seen very little evidence that mass surveillance leads to fewer terrorist attacks, catching criminals, or is effective in any way. The NSA have been unable to provide a single example of a terrorist attack being prevented by their mass surveillance program.

Secondly, mass surveillance predominantly spies on law abiding citizens. "If you make privacy illegal, then only criminals will have privacy". Terrorists aren't stupid - they know how to use Tor, how to use encryption, how to hide their tracks.

Mass surveillance is about control of the population, nothing more.
