What about all the people who have hit their wives/girlfriends, suspend them all too. Randy Moss hit a cop with a car, suspend his ass. I'm not defending what Pacman allegedly did. I am saying that you have to be consistent with your punishments.
If you want to base punishments on who has hurt the league most, Merriman deserves to be suspended indefinitely. It isn't known how involved Pacman was with the shooting, if it comes up that he had anything to do with it, then kick him out of the league. As far as anyone knows, his friend did it without him knowing, kinda like DH in Playmakers.
