Well Don, in the military you are judged by your actions.

In the case in point:

The Helicopter Crews

1) Those debriefing the pilots and the US ground troops on patrol that day had no problem with it.

2) Within fourteen days of the incident happening Reuters saw every scrap of coverage that MNF had of the incident, they saw every transcript and read all the reports and they had no problem with it.

Hence no charges and no Court Martial

Pfc Manning

1) An Analyst with Top Secret Security Clearance

2) Copied classified material onto his own computer knowing that to be in breach of regulations

3) Passed that classified material on to a foreign national knowing that to be in breach of regulations

Hence Pfc Manning finds himself under arrest, charged and about to face Court Martial

Seems pretty fair to me.
