What is your opinion, foreigner, did he think that the military has been treated unfairly by the civilians, or did he think military is at fault and he can't bear the disgrace?
I am not sure it has to be an either/or scenario nor am I sure that other factors should be precluded based on what I know, which in this case is scant.
Having said that I can't fathom why a military prosecutor would feel the need to bear any proposed disgrace. It simply doesn't stand to reason. Military lawyers are not in the same league as the brass who go about doing disgraceful things or covering up disgraceful actions. In this case we don't know if such actions exist or if they do, to what extent.
My guess is that something much more serious than what we suspect is what lead him to do this. I have not ruled out that his life was already threatened by others wanting to keep something from seeing the light of day. That's my guess but I've nothing really to base this on other than the facts: he was a prosecutor; was privy to information we wouldn't be; stuck a loaded pistol to his head and pulled the trigger; hasn't a known history of this kind of sh*t.
I pointed out that he was used to shooting at targets in the distance and not sticking the barrel in his gobthe more I think about it, the more this looks like a cry for help
I was wondering about that too but sticking a loaded pistol to your head may make you waver a bit and become weak in the wrists, the recoil could account for the glancing nature of the shot but without knowing what he was thinking, it becomes difficult to say.
