I think what he's mentioning has nothing to do with 9/11 though, right? He's talking about football hooligans. I only know that there are such scenes in soccer here in Europe and it can get pretty rough when they clash.

Not wearing a seat belt was also not a problem pre-1984.

Tell me about it. I got to lay on top of the families suitcases in the back of the station wagon on road trips. It’s so much easier to sleep like that.

Yes, until you die in an accident that you could have survived with a seat belt.

Which is exactly why my everyone in my car wears their seat belts. But that doesn't change the fact that it was easier to sleep when laying down in the back of the station wagon.
