Both parties are now suing each other. If you listen to the tape, it appears the punk is really f-ing the woman. That might be considered an assault- ie “fighting words”. Even after he sat down the punk again effed her which justifies the father at least trying to beat his ass. I’d award the punk a kick in the butt and the father and daughter the cost of their Open tickets.
What I saw was the old geezer grabbing the guy’s head and punching him FIRST. That looked to me like a clear cut case of self defense - I think the kid went easy on him.
Whatever was said doesn’t matter. That’s not an ‘assault’. You can yell all you want, that isn’t illegal. If I’m in the jury the old geezer is toast.
