Yeah bring in video refereeing! Obviously the referee still has the final call but where a penalty, offside, freekick etc. is hotly disputed the fourth official should communicate with the ref and tell him what's what. Video replays should be used to support the referee's/linesmen's decisions and not undermine them. If it eradicates cheating and human error it can only make the sport purer therefore the teams that really do deserve to win on the day should win because of their ability and not because of fortuitous refereeing decisions.
