That completely misses the point. We are talking about fouls, physical fouls, not offsides or goal line decisions they can be absolute. Fouls have to be observed by the ref and he has to decide who did what to who and the severity of it. Even try to decide things like intent. This will always be a judgement and we have relied on the good faith of referees to make these judgements just as well as they can.
The simplest of these fouls, in theory, is handball. We could simply have a rule that the ball must not touch your hand and arm, but of course if you did that players would simply try to kick the ball onto an opponents arm. Judgement must be used to try to make the game fair. You cannot film intent. VAR just slows that process. We have to do what we have always done, trust that the ref is honest and abide by his decision.
And all of this is because the media loves to create controversy, it makes good tv. Fans will always doubt the ref when a decision goes against their team. They should be reminded that the game is impossible without the referee and just accept his good faith. Of course there will have been corruption, I think it's fair to say that most of that comes from the players, so if we go down the road of mistrusting refs we will lose the game.
