Give the Umpires the respect and authority they deserve.
I don't care what techology goes to support them, but once the ump makes a decision, that's it. Right, wrong or disputable, the Umpire has the final say, and once it's made, the players, media, spectators and staff should accept it and move on.
I know some people think such discussions are enjoyable, but I think for the majority, and also for the good of the game, accepting the decision and moving on would make the game more pleasurable. At worst, it's an honest mistake...again, just accept it and move on.
BTW, if you check the rules, thats pretty much how it reads.
