Besides that. The saying is that the fans are part of the game. If they think they can get away with crap like that at a home game then they can suffer the penalty against their team.
There was a fan who ran out on the field at the chiefs pats game. 15 yards against the Chiefs.
I think the fans participating is a little different than the opposing coach using a tool that the officials use for the game. This is just my own opinion but he just reminds me of the sneaky little kid who just loves to annoy people he does not like.
