I thought they were sort of pvssy. Throwing snowballs at the cars because they wouldn't get any thrown at them. No much of a fight (or may UofO students are confused as to what a "snowball fight" is).
Also, this is why the elimination of gun-free zones and concealed carry would create a more interesting world. When the jacka$$es started hitting him when he got out of the car (especially the one in the face around the 1 minutes mark) , it would have been very interesting if there was a risk that geezer whipped out a pistol and capped a few of the kids.
