ELI5:[Worldcup] With the high amount of referee errors why don't they just use video replay to determine the judgement?

The governing bodies don't want the game to be stop-start. They want to keep the fluidity of the game.

This does, however, mean games can be quite controversial (take the penalty last night for example).

The goal line technology is starting to be phased in around the world, but then it's hard to implement that into lower level football.

It would be better if at the more important competitions they had it, but FIFA is a stubborn old mule.
