As someone who has an unhealthy distrust of refs, i agree with this

I came across the below article about implementation of VAR in a local paper which ties in with the above point that i feel is the elephant in the room. I think the FA is worried that the golden goose that the Premiership is cannot be associated with incompetence/corruption.
"Politically motivated in order not to embarrass match officials, the bar to overturn a decision has been set high, but nevertheless subjectively, and its poor implementation is making a farce of a review system that can work well.
In cricket, umpires are not protected if they are found to make a wrong decision, although they have a marginal error filter under "umpires call" which works well.
I think for VAR to be allowed to work without politically motivated intervention by the governing bodies something similar to "umpires call" will need to be brought into VAR.
At the moment its not working for me. Yesterday's game against Norwich and the decision by VAR not to award a penalty for a clear foul on Azpi was a joke and provides strong evidence that the governing bodies have simply got VAR wrong"
For reference, the Umpire Decision Review System (UDRS or DRS) is a technology-based system used in cricket to assist the match officials with their decision-making. The components in UDRS are:
Television replays, including slow motion.
Hawk-Eye, Eagle Eye, or Virtual Eye: ball-tracking technology that plots the trajectory of a bowling delivery that has been interrupted by the batsman/batswoman, often by the pad, and can predict whether it would have hit the stumps.
Snickometer or Ultra-edge (Hawk-Eye's version): directional microphones to detect small sounds made as the ball hits the bat or pad. The use of the original Snickometer was superseded by Real Time Snicko in 2013.
Hot Spot: Infra-red imaging system that shows where the ball has been in contact with bat or pad. Improved cameras were introduced for the 2012 season.

Edit: note the years this technology was implemented (even earlier for American sports).
