I think the issue with a handball is that the only question is "did it hit his hand?" - it's binary. Unlike eg fouls, where some people may think it's a foul and some not.
You are correct, it is binary but the when it goes to VAR (not VAR initiating the process as it were) for a goal the two things they are looking at is:
1. What side am I looking at i.e. what was the on field decision
2. Am I certain of my opinion.
Given there are 2 options there are 4 outcomes.
1. I agree with on field decision, I am not certain. - On field decision remains
2. I agree with on field decision, I am certain. - On field decision remains
3. I disagree with on field decision, I am not certain. - On field decision remains
4. I disagree with on field decision, I am certain. - On field decision is overturned
That means that you can kind of give them the benefit of the doubt on the first one. Thats being kind though as the defender pushes Mitoma just before he controls it which should 100% be taken into account. The second disallowed goal though, every angle we have so far shows it as either massively inconclusive or very much coming off his hip. Ref gave the goal. VAR shouldn't overturn.
So if VAR reviews a goal and decides it has come off a hand, it has to rule it out - the decision to give the goal is a clear and obvious error.
You have to look at it like a court. As a juror your job isn't to have an opinion, its to look at the evidence and if its without doubt you find them guilty. You don't say " I'm pretty sure". If they see it comes off a hand then yes. Thats a clear error. If they think it might have done but aren't sure then they stick with the on field decision.
I agree with you that overturning that goal was ridiculous, my issue with the video was (a) that decisions like that seem to happen every week - it's **** refereeing, but not corruption and (b) the video's attempts to call basically every standard foul a yellow card make it look absurd.
Bad officiating happens far more than it should, but it's incompetence not corruption
Oh I completely agree and I usually preface my posts on this topic with that. They are just bad at their jobs. Its not cheating. And yes it happens every week but I haven't seen a game where one side has been so utterly bent over by it in a long time if ever.
