I agree this umpire was wrong and he was also arrogant. The only recourse a parent spectator has is to contact whatever organization that trains/assigns these umpires and make them aware of the situation. It's up to the association to address the umpire. Nothing good will come from a parent addressing an umpire after the game. I wish parents who complain about the umpires would don the gear and work a few games to experience what life is like for an umpire.
