It will be a military Court-Martial. Wanna bet which side the military officers on the court have sympathy for?
If he had used the term "nigger" I suspect it would be in his record and he would have been demoted. Or forced out if it had happened more than a few times. But apparently the officers were ambiguous about his wanting to "cut throats"... etc.
So, no I don't know what side they'll be on. A few years ago I would have bet their loyalty would be to the men and women who were gunned down. Now - I don't know. What's your best guess?
