at least with edged weapons.
Military officers are human beings: cruel and kind, honest and venal, and all the other possibilities. Paragons? No.
For the record, I've never been court-martialed; I've had friends go through the experience, two of which I was closely involved with. The guilty one got jail time; the innocent one walked. The few civil trials I've had direct knowledge of didn't have any such proportionality involved -- for the most part, they turned into jousting matches between debating teams, with the result directly proportional to the amount of money the defendant had to spend on counsel. Purely anecdotal evidence, granted without argument; but it does dispose me to be rather more tolerant of military officers than you seem to be.
The one thing that does disturb me about the "military tribunals" notion is that they'll seemingly be here, and staffed with REMFs more like your described experience than actual serving-in-the-field officers. That does make the notion less attractive; on the other hand, I've never seen anything about the position of judge, prosecutor, attorney, etc. that implied any sort of Divine gift of rationality.
So if I, in my travels -- and I do fit a few of the guidelines -- run into problems and get hauled before a "military tribunal", I'll take my chances with a relatively light heart, at least compared to facing equal charges with nothing between me and Leavenworth but a court-appointed post-teen-age hack. OK?
