Somebody be specific about how he committed treason.
See: Helsinki... anyone who's ever worn the uniform would quickly identify this egregious act. Granted it wasn't the first time, he's said and done it numerous times in country. What makes it treasonous, is doing so on foreign soil while standing next to an avowed enemy of this country.
Clearly we are not at war if you want to focus on it from that perspective, but again, there's more than one way to commit treason. Ex: Cowardice in the face of an enemy.
