When an official makes a mistake nothing happens! Usually the fellow officials surround them like a downed buffalo and deny the "masses" the right to know the real answer. I say, nut up and admit it when you make a mistake or when it is time for you to walk off the mat and let a new official break into the elite fraternity.
I can assure you not all officials fall into this category. At the Newton TOC, a longtime respected official, after making a difficult call, sought guidance from fellow officials on the interpretation and application of the rule in question. After conference, the official did "nut up" and overturn his call.
