Growing up in the U.S., we were all taught the history of our country, which included Benedict Arnold. But very few see a parallel to Benedict Arnold in Snowden. They cannot see how someone whose main claim to fame in the press has been, "They are watching you!" has exposed state secrets. Neither do they think Julian Assange is Benedict Arnold. Julian is just posed as a well-meaning but much misled Australian hacker that probably got framed in a rape case and is on the run, like a modern day Frank Abagnale, but with state secrets instead of fake checks.
The fact is, our governments need respect in order to keep secrets better, but prosecuting and hunting down these people is not the answer, neither are other "control" techniques. They just need better security. If they had better security, I for one would respect the fact that they said, "Oops! I guess I left the playbook in front of the press tent. I guess I should keep it on my person at all times."
