I agree with her.
I think it is important to realize that authorities aren't necessarily caricatures of evil like Dr. Evil from Austin Powers. I don't believe Gen. Keith Alexander is conspiring to undercut democracy. I believe he is earnest but misguided. And I believe the present institution rewards and promotes those who are earnest and misguided. I believe it is simply an emergent phenomenon.
Of course there exist evil people who will intentionally abuse their power for selfish gain. I do not believe though that blatant evil is the dominant force in the world. I think the most common case is that there are just people in power who are trying to do something "good," yet they share different values and concerns than their opponents.
How could someone be "good" yet conduct mass surveillance? (1) The belief that terrorism represents a grave threat, (2) the belief that mass surveillance is the best way to combat terrorism, and (3) the belief that their implementation of mass surveillance doesn't represent a significant threat to civil liberties.
This is important to consider when you oppose someone's actions and policies. It won't be productive to assume your opponent is evil. Rather, it will be better to have an honest intellectual discussion and debate about your values and the pragmatic dangers of secrecy and mass surveillance.
