This happens in team sports from time to time, and in most cases it doesn't really get to be that big a deal, unless it is a key player for a specific side.

Plus, there's plenty of serious stuff that people do that get overlooked because of sporting talent. Look at Michael Vick and his disgusting dog fighting ring, and then he's back in the NFL after a couple of years in the clink.

Add in the fact that the story wasn't 100% waterproof, and I agree that lots of people thought Tyson got a raw deal with that particular incident.
