I always wonder when I see things like this, why on earth would you pick on a stranger with two long sharp metal poles? That's just stupid.
There are a number of ski buses going from NYC to Mt. Snow. One of them who's clientele are mostly snowboarder allow them to drink on the way up and down. I've seen that bus company pass out beer out of a cooler. While I don't think this incident has less to do with alcohol and more to do with idiot. It kind of gives you an idea of what the environment could be like.
One time I was at Windham Mountain, a small mountain in the Catskills, 2.5 hour drive north of NYC. Lots of families go there, less idiots. I'm on the lift and a teenager and his friends in front of me start throwing snowballs at little kids coming down the mountain. When I got to the top they were zooming off. Back down near the lift line I was looking for him so I could point him out to security (then it's up to them if they want to do something, I did my part). I see him and some guy yelling at him. I walk over and apparently on the way down the snowball throwing teenager tried to jump over the guy's young son and hit him on the helmet with his ski. That guy was pissed! I would be. He was yelling how they all took off as fast as they could but luckily he was good enough to keep up with them. The teenager had a pretty distinct helmet (stickers). The staff tried to calm the father down and surrounded the teenager who looked scared (yeah, now you're scared). In about 10 minutes an officer showed up (small town so he probably wasn't far). After the father explained the situation, I chimed in and told him about the snowballs along with a couple of other people who saw him throw them as well. They took him away. Good job on everyone's part.
