It was fairly short, probably 3 pages of dark humor, however he got the point and in now at the very least understands why this is important. I think many Americans (especially those who grew up in the cold war) do not realize how serious this is.
There was a campaign to white wash all the information, NPR, CNN, Fox, they really did not cover the story in a clear cut manner. The fact the government denied everything, and there was an abundance of information shut a lot of people down and out of the conversation.
That being said, every (older - 40+) person I talk to think Snowden was bad, until I ask the question, "Why did we fight the cold war?" You cannot spend decades battling Nazism/Communism only to accept the same practices a decade later. It's pathetic. Often after a clear explanation of what the NSA (or what we know the NSA) actually does, quickly changes their minds.
All they really need is an explanation.
