Changing history to meet people's sensitivities is a bad idea. The history on that wall: He was a Hell of a ball player, NOT he was a Hell of an upstanding citizen.
Do we have to have a yearly review of everyone on the wall to make sure they meet community standards? Now, should we scour police records and news stories and remove anyone who ever hit his wife, snorted blow or said something politically incorrect?
Further, he was found not guilty. The thing he was found guilty of was, I think, trying to steal his own freaking trophy back.
