Snowden is a traitor. Three weeks before the USS Abraham Lincoln deployed in August 2000, my office - the Security office - got a phone call from someone with a foreign-sounding voice who said that when we pulled into port overseas, they would blow up a ship next to ours. We pulled in to Dubai in early October - we were nervous and kept an eye on everything, but nothing happened. Four days after we departed Dubai, the USS Cole was bombed by a boat that pulled up next to it. In other words, that person knew something...and if we'd had PRISM then, not only would we have found the individual on short order, but we'd have found all those he had contact with...and one of those who helped plan the bombing of the Cole turned out to be one of the 9/11 hijackers. PRISM could have prevented 9/11, if we'd had it then, and by extension could have prevented the decade of right-wing neo-con insanity (and 5000 American military deaths and 100K+ Iraqi deaths) that followed.
Likewise, Bradley Manning is a traitor. He's not on trail because of the video of us killing a reporter - he's on trail because he released 250,000 diplomatic cables, each and every one of which had the potential of either exposing agents and/or contacts, or exposing how we react to certain situations, and what assets we may or may not have.
