Isn't that the point? The only one that could be sued is the guy you agreed to let kill you...
Maybe their waivers are covering all possible scenarios, but I'm skeptical. Once fists start flying with people not trained to fight, all bets are off. You're already dealing with someone willing to trade blows with a stranger due to some stupid disagreement. Expecting restraint in all cases isn't being realistic.
- Someone gets beaten down and before the officer gets a chance to step in, the person with the advantage delivers one last blow that does lasting damage to the recipient. The person can't work because of the injury. Spouse wants justice for lost income or hospital bills, claiming the bout should have been stopped.
- A person that is being beaten down is in a gang. His 'brother' takes offense and the fight broadens out or escalates to people not involved in the initial melee. Someone gets killed.
I'm all for watching two idiots beat themselves up versus getting into a car and committing road rage, but I think they are playing with fire.
