So just to be clear what you mean by this: the army shouldn't be accountable to civilians?

Oh! It's from a movie!

Whole different thing.

Jack Nicholson's character basically ordered some off-the-books discipline that killed a man. When he was caught trying to cover it up, that was how he justified it.

Glad you put it into context for me. It's an alarming sentiment to come across without it!
