Humans are going to miss calls, we can debate using robo-umps for that. BUT, yelling at an injured player to get off the field, tossing a manager (even Boone) for something a fan yelled, then refusing to acknowledge that you made a mistake are not acceptable. I think my issue is that there appears to be no consequences for this type of behavior. Umpires are never seemingly punished for their behavior (not blown calls, those are errors and happen), that seems to be the bigger issue.
