Good questions..
Thats why I wonder if this is the standard attitude. Guilty till proven innocent in a court martial and the Article 32 hearing is nothing more than a process that rarely does anything except rubber stamp the obvious the guys guilty...Court Martial.
I wonder how many Art 32's didn't go to court martial.
If the percentage was in the 60s or 70s, for instance, it would put the nearly 100% conviction rate at trial into perspective.
But if (as I suspect) nearly all Article 32s go to trial, then it sure looks like the cards are stacked.
BTW, this article, at Defend Our Marines, has conviction rate percentages for all services: "Unequal Justice", US News & World Report.
Maybe one of those "military justice" organizations would know the answer to the Article 32 question.
