Are you serious? Even if he was a double agent he still brought positive change. He opened not only a national dialogue, but an international dialogue. And that dialogue continues even today. There have been numerous bills that have been brought to be acted upon.
People now know this stuff is going on. Some people have changed their behavior. Some holding information back, and others opening up the pipeline. Hell even the little old lady down the street knows she is being spied on.
And last but not least he exposed the sham that is the Nobel Peace Prize when he was passed over. And yet a guy who has killed countless people has won it.
I could go on and on. But it seems like you are getting the weekly brainwashing memos talking about how the public doesnt really know the truth, and only us insiders can protect the nation. I get those memos as well bro. But I choose to think for myself.
