There has been uproar in the football world as England and Mexico suffered from bad referee decisions in the 2010 FIFA World Cup Round of 16 that could easily have been spotted by a video ref.
The English team and their fans were celebrating the equalising goal in their Round of 16 game against Germany, only to be mystified when the ref wouldn't give England the tally.
The celebrations turned to screaming at the Uruguayan referee in charge of their game, as neither him nor his linesman saw the ball cross the German goal line.
Replays of the shot clearly show the ball going over the keeper's reach, hit the bar, and bounce a yard over the Germans' goal line before it ricocheted back off the crossbar and back onto the pitch.
Many people remember the "goal" that England scored in the 1966 final against Germany. That was a closer decision than this, and it was given. Is this payback for 44 years ago?
The blunder took place when Germany were up 2-1. The goal could have been a turning point, but instead Germany went on to win 4-1.
Even Prime Minister David Cameron has called for the use of video technology.
He was at the G20 summit in Canada when he said, "I do think that the use of technology in sport can be a bonus.
"I'm a keen follower of cricket and tennis, and I think the third umpire has been a great thing, and the machines that bleep at Wimbledon are quite handy too.
"Maybe that's something that football could now have a look at."
After the game Fabio Capello commented, "The Lampard incident was one of the most important in the match. The referee made one of the biggest mistakes.
"We scored. It is incredible. In this period of technology, in this period where we can have five referees, we cannot decide if that was a goal or not."
Former English captain Alan Shearer led calls for goal line technology to be introduced in football to ensure that goals are correctly awarded.
"All the ex-professionals and the superstars want it, every single person is calling for goal line technology except for one person.
I'm sure if Spain or France had a decision against them like that, the laws would be changed just like that.
In their match, Argentina scored a goal against Mexico that should have clearly been disallowed. A video ref could have spotted it, but the referee allowed to the goal to stand even though there was a blatant offside.
FIFA have ruled out any more experiments with goal line technology. England's FA and the Scottish FA voted in favour of it, but The Welsh and Irish FAs sided with FIFA.
Blatter said, "It is often the case that, even after a slow motion replay, 10 different experts will have 10 different opinions on what the decision should be.
"Fans love to debate any given incident in a game. It is part of the human nature of our sport."
Show the replay of the English equaliser to 100 experts, and they will all come up with the same result. IT WAS A GOAL.
How many more bad decisions will it take before Blatter and the FA realise that video technology is needed in football
It's the most played sport in the world. It is a billion dollar industry. Yet technology is not used to make the game fair.
