Anyone else find it funny that amid all the clamouring here for the use of technology in umpiring decisions, a decision is referred to the third umpire that is totally inconclusive and a batsman is given not out because you couldn't tell?
This is why technology is not used more than it is. Every time it is experimented with for anything other than black and white, behind or in front of the line decisions, it is generally inconclusive and simply serves to complicate things. For LBW decisions it is impractical because many of the things used in determining an LBW decision are either abritrary (was the batsman playing a shot?) or difficult to tell on replay a lot of the time (was the ball going to hit the stumps?). That leaves pitching in line, where it may have a purpose. For catches it isn't used because camera angles make viewing the position of a ball relative to the ground very difficult, and catches low to the ground viewed on replay are very, very often inconclusive. For reference, see the hundreds of arguments on this forum about whether or not X catch by X fielder was genuine. If nothing else, that should indicate you can't use replays to determine those decisions much of the time.
That leaves run outs, where it is already used, and no ball decisions, where I would support the introduction of technology. For LBWs and catches, technology is nowhere near 100% reliable in improving the umpire's ability to make a decision, and would simply delay the game and undermine the umpires for no valid reason much of the time, especially if one assumes that technology like Hawkeye wouldn't be used because it is predictive and therefore not verifiably accurate.
