So I guess I get to be the legal bad guy.
Bobby was not at his home,
The man had no intentions of hurting anyone
The man himself did not injure anyone.
Was it a clown move of the man? Yes.
Was it illegal of the man? Yes.
Forget that this is in a stadium, that means nothing in the legal realm. Consider that this happened on the streets.
If a man runs in the street with a smoke bomb thing like he did, can you leave the side walk to attack him?
It boils down to did B8bby feel threatened and he use the minimum force needed to stop the threat.
Its close because of the smoke, but I say Bobby will have to cough up some cash...you just can't attack a guy because you feel like it.
