Except the NSA has something like 30,000 people. It's hardly as though every one of them are involved in monitoring US civilian communications. Maybe, just maybe, some of them are demoralized because they have not a damn thing to do with anything in the news, yet they're being treated like demons.
There's this thing called "guilty by association".
If you work for the Mafia, even if you're just driving the boss around and never do anything illegal yourself, you are still a member of the organized crime. And you are doing your part in supporting it and keeping it running, even if all you do is drive a car. You are a cog in a machine, no matter if you work at the NSA or at Google. But you can't claim "I'm just a cog" as an excuse if you know the machine is evil.
