it's hard to say this tantrum behavior isn't fostered from top. I mean, that's straight up tresspassing like any other non-coaching, non-playing fool with a sideline pass who's angry.

Him doing so signals to fans that tantrums leading to illegal behavior are OK. I would guess this significantly increases the ewe's legal exposure for incidents like "the bottle"

Plus it doesn't help that Harlan looks like he's missing a bottle (of two kinds) himself after the game.
