Edward Snowden should be pardoned for his actions in blowing the whistle on NSA criminal activity. However if he leaked other information to foreign governments he should be subject to prosecution for those actions. It would be interesting to see what credibility the government has with the public in making this case. Of course the public would never know because the trial would have to be kept secret in the "interest of national security". Of course by that point the secrets are already known to those who would be interested. And down the rabbit hole we go.
