Please see the attached demo. Remember to set "sv_cheats 1" and "mat_wireframe 1 " for the full experience. Watch him follow packs of players through walls, anticipate VERY clearly the movement/direction of others, much to his advantage (or so he thought).
I have other demos where i do not believe he was wallhacking (other maps such as complex, etc), so in my opinion he is not always doing this (hence he can claim/cry/complain about how he doesn't hack), but this particular evidence speaks for itself.
This is also NOT the first instance of this (see here) as witnessed by other admins.
