Can't condone death threats obviously, but wouldn't it be a good idea if a referee who had such a stinker, VAR aided and all, was made to sit out a few games by the FA anyway? I don't see how a referee can get away with making such obvious mistakes scot-free. It displays clearly the ref in question is either incompetent, blind or biased and neither of those explanations are satisfactory at this level. Easy new rule proposal: if a decision for which the ref had the benefit of VAR is overturned after the game that ref is made to sit out the next round of games.
In general I think English referees are far too protected. Over here in the past 10 or so years whenever there has been a controversial decision made by a ref in a televised game that ref was shown the TV image afterwards and asked to comment/explain. It's happened quite a few times, especially pre-VAR, that the ref had to hold their hands up and say they misjudged the situation. Shit happens, people make mistakes, but quite frankly I can't see how a referee can just be back officiating another game a few days after such an inexplicably bad decision. It makes a completely mockery of VAR and refereeing in general.
