I've seen him on before freekilling before, well attepting to at least... I'm sure a few others have as well. I joined the server and he was standing against the cell door on ba_jailstationx and killed the one other guy in there so I started up a demo right after that.
Clearly shows him attempting to kill me, and not being a proper CT. >.>
I tried to attach the demo via the attachments thing but that didn't work so I uploaded it to mediafire.
