Absolute waste of time, they dont even get it right every time in the professional game even at test level so why bother with amatuer stuff. Just a money making gimmick IMO.
Umpiring mistakes and percieved 'cheats' are unfortunately all part of the game, its the same in every sport, human error exists and at times will affect the match and outcome
What next? Cameras on tripods at both ends of wicket and square leg so umpires can sit at home umpiring the game and using reviews and replays to determine decisions, I dont think so
