Techical Foul-Ejection

[Dan_ref]

Here's what you missed. Pay attention, it's important:

Never, never, never delude yourself into believing that as a former official you have the standing or the right to explain, justify, criticize, discuss, agree with, disagree with, or in any way comment on a call made by a floor official during a game. Your role is a fan, you have no standing whatsoever as an official. Being a former official grants you no special status. If you were a working official this behavior would lead to you being slapped down by your association. So just keep your yap shut. Got it? Yap. Shut.

That said, if this father came to me after a game to discuss what happened I would have walked past him without acknowledging his existence....except to game security, who would be told they need to take care of some jerk.
