I wonder if he left the kid his card....I kid, I kid.
Too many of these incidents to shock me anymore but, I can't get my head around how a middle aged, well educated person, with no prior record could mentally get themselves into a state where, in front of a bunch of other parents and kids, they take a ridiculously extreme and stupid action that will without a doubt materially harm themselves and their loved ones and likely destroy their own lives, much less the life of the kid he chose to attack.
You have to think that there was at least a minute or so between the time where his kid was elbowed and the time that a 6"3 230 lb bleacher bum could have made it on to the ice to attack the perpetrator....at no point during that time period did a brain synapse fire in this guy's head telling him this might not be the best idea?
