Not defending Bennell - probably should have been given what the Richmond players got, but maybe they didn't go as hard because it sounds like he was in a messed up mental state and went to households with only a few people there, rather than loving life getting lappies at the rippers in a crowded venue.
Melbourne may have already given the AFL the indication that they will release him so whether it is 1 week, 4 weeks or 40 weeks won't really matter if that's the case.
