I love how you feel the need to requote posts people have already responded to, as if it proves something. Player discipline is publicized and all baseball officials (players, managers, GMs, etc.) pay a price for poor job performance. And the umps, who are the authority over the game and arguably the ones who should pay the steepest price for poor job performance, appear to face no repercussions. Ever heard the phrase "perception is reality"? You'd think MLB would want to publicize their accountability measures to let people know there's a fair balance.
Do we need to know that Bob Smith was fined $6,000 for prematurely tossing a player? No, but MLB could come out and say "we review all umpires performances and they are fined/disciplined/given demerits based on poor performance", and actually show that they have a structure in place for this. I'm sure there is some review process, but it doesn't seem to be a very good/effective one.
I go back to my police officer example, going with the principle of authority figures. Is every last bit of cop discipline publicized? No. But we know it happens, and there are enough public cases to show that cops aren't above the law. I agree they need more freedom than the average citizen to do their jobs effectively, but they absolutely should be held accountable.
Umps appear to face no accountability, which is only enhanced by the fact that certain umps who have sucked for years still have jobs, and examples of umps flexing their muscles just because they can are becoming more frequent.
You say the last thing we need is players/managers baiting umps, then you say umps have been confronting players managers for a long time - yet you don't think they should be openly held accountable. I don't even think I need to point out what a ridiculous double standard that is. If an authority figure can't properly exercise that authority, they should lose it.
