Hockey's a dumb "sport"

The Rockford IceHogs' playoff game of this past Saturday night, as described here, is eloquent testimony to why local government should not own a hockey team.

As I've asked here previously, why don't the authorities arrest these hockey goons for fighting? Such conduct is against the rules of hockey. Such conduct will get you arrested in almost any other setting. Why do these cretins on the MetroCentre ice get a pass?
