I mean, in the US, cops aren't obligated to put themselves in harms way, so a referee certainly wouldn't be. They might not get any more assignments if they stand back and let a full on line brawl happen though.What legal responsibility does a referee have to put themselves in harm's way by intervening?
I would think they sign a contract with the league before they're permitted to ref, so I'd be curious what the contract says about physical altercations
But that is talking in the extremes. Refs are hopefully de-escalating things by throwing guys out or giving penalties before things boil over. With this particular incident, you can't tell if things had happened to this point where some sort of incident should have been expected or if that guy was just a crazy loose cannon.
@Ducks4Cup When you're talking about in public, you also have to take into account where you live. Some places you have an obligation to run away before responding with violence. Some places you get to go into Costco in your "Running things since 1776" shirt and scream that some old lady is making you feel threatened before you get to shoot her.
On the ice is different, because you have implied consent to certain acts of violence, but so does your opponent. If you're Phil Kessel at the faceoff dot and John Scott is telling you he's going to push your face in, you're probably allowed to be swiping at his legs while running away, since slashing (and fighting) is not out of the realm of expected hockey. Going McSorley to his helmet is probably no good since that is out of the realm of expected hockey plays.
