Vitale obviously stuck his leg out for the trip. He deserves worse than boos. That's dirty play.
Doesn't matter, the guy was hurt. And if you ever played the game, you know stuff like that happens without any ill intent, it's the heat of the moment and being just too far away to line up a clean hit. Been there.
And I didn't hear any complaining when the same play happened the other way in the last period...
Cheers!
