While I agree Snowden did a heroic thing, he is very visible due to being a whistleblower. There are potentially lots of people doing selfless and principled things that stay secret, since secrecy really is important in that business. There is a tension between citizens need to keep their government from going astray and the government's need to outwit its adversaries. It's pretty clear to me we have gone too far in the direction of a surveillance state, but those agencies still serve a good purpose, too.
