Football – the beautiful game – has a natural ebb and flow, the speed and end to end nature of the game should be interrupted as little as possible. Do we want to stop the game for every debatable decision. Was it a handball, did the defender play the ball or take out the man, which way should the throw in be awarded, should it be a corner or a goal kick, was the forward marginally offside or not etc… Where would it end?
Referees and linesmen are human and therefore cannot be perfect but if there is consent that we accept their decisions, right or wrong then we can preserve the essence of the game. Its not all about winning otherwise fans would not support those teams that have not enjoyed success for decades.

There would inevitably be a cut off point – a level of the game at which it would be too expensive and impractical to employ this technology. More people play football in amateur teams on a Sunday than watch professional matches on a Saturday. At present they play the same game, with the same rules and the same ethos – that the referee should be respected.
