They are trying to tie Tochett to organized crime. Gretzky's wife isn't really in legal trouble, the police have already stated that she's more of a witness to the betting than a ringleader. It's the people who organize the betting that are looking at legal troubles.
The NHL has also already stated they won't be involved at all. None of the gambling was done on hockey games.
Still, it definitely looks bad, and the media is going to town. I also read a few very negative artcles about Theodore and Propecia. Geez, give the guy a break, he's losing his hair.
