Just as a point of note, witnesses and video aren't the only points of evidence. As a trial moderator, Jorj has access to the logs which shows combat between individuals and also provides snapshots of the fight. Your statement that "A trial mod giving a warn with no video evidence not even witnesses isn't allowed and as such should be removed" is just flat incorrect.
If you're dealing with a trainee that is minging, using homophobic language as you state and refusing to stay in bunks you should be calling a staff member to address the conduct, as that's the easiest and cleanest way to go about things.
Secondly, this warning is from over a month ago. Why the delay?
In either case, @jorj, your side please.
