"...For treason turns out to be unique in American law. It is the only crime that the Constitution forbids Congress from defining. It is the only crime to which a court may never accept a confession given to the police. It is the only crime for which restrictions are laid down on how much evidence juries must hear. The Constitution itself underscores that the Founders feared treason law. ...a person has to do one of two things to be a traitor: either levy war or adhere to (form an attachment to, the Supreme Court once said) our enemies, giving them not only aid but also comfort. The two-witness rule has also made treason cases rare in American history." http://online.wsj.com/article/SB10001424127887324688404578543410828226862.html http://online.wsj.com/article/SB1000142412788732468840457854... "…Snowden’s disclosures may have helped the nation’s adversaries (though I’m skeptical as to how much), but treason requires more than that. It is not enough to release important national security information and consort with the nation’s rivals. Snowden may be prosecuted one day. Barring significant new disclosures and developments, it won’t be for treason." http://www.volokh.com/2013/06/19/snowden-did-not-commit-treason/ http://www.volokh.com/2013/06/19/snowden-did-not-commit-trea...
