> So what you're saying is, in the United States "treason" is defined so that a helicopter gunner who murders journalists and unarmed civilians is a hero while the person who exposes this war crime is a traitor.

No, what I'm saying is that murdering journalists and unarmed civilians is not treason, because…it's not.

Now, was the specific act you referred to a war crime, or a case of mistaken identification, or legitimate action against an armed group or individual within a group, or something else? Beats me. It's not my job to decide. Nor was it Manning's job to decide, nor to leak that information because he didn't like the decision of those whose job it was to decide.
