If you're unfamiliar with the UCMJ, I suggest you look up UCMJ Art.51 (c) (1).
The UCMJ at this stage of a case doesn't just suggest that the doctrine of presumed innocence be considered, it demands it.
So true. There's the "right way" and the "real way" (most things are done the "real way") and sometimes the "real way" is underhanded.
