Here we go again. I’m certainly sorry that the kid got a concussion, but it was the result of a legal, clean hit in a hockey game. Injuries take place in sports, and as an athlete you agree to certain risks when you step onto the field of play.
Even if the hit is a penalty, it’s a part of the game. In very rare circumstances, criminal prosecution could be necessary in cases of extreme violence far outside the scope of a sport. For example, if the opponent tried to slash the kid’s throat with his skate blade, then it could be argued that the conduct went from a part of the game to a criminal act. But a normal sports collision, whether or not it resulted in injury, can never be prosecuted as criminal.
But, of course, the parents don’t see it that way. Even though they signed the release forms to allow their kid to play hockey, they are running to the courts because of an injury he sustained. Undoubtedly, this is the first step of a lawsuit against anyone with money: the kid who made the hit, his parents, the school, the ice rink, the athletic association, and the Zamboni family itself for making that ice so darn hard!
