Ever since the introduction of VAR we have seen endless excuses, chicanery, obfuscating, rule changes, and downright lying in order to justify what was utterly flawed as an idea, never mind it's implementation.
The excuse last night for the challenge on JJ was that there "wasn't enough contact". WTF? How do you measure how much is enough? They made the decision in order to protect the ref and for no other reason. Before the end of the season you will see a Pen where the contact is less. Add this to "phase of play" where no-one really knows when they start or finish, interfering or not (Liverpool's goal last night), the handball rule etc etc.
All hugely subjective so impossible to be consistent.
I can accept a Ref making a mistake, what I can't accept is a third party doubling down on the mistake and that is one of the myriad problems with VAR.
It. Doesn't. Work.
