The Instant Replay guys led off this week with the Dempsey call, and inexplicably they each get it completely wrong. On replay, it looks very strongly like Dempsey only swept his arms through the arms of the defender who was holding him. It certainly isn't clear at all that he made contact with the defender's midsection. No way should that have been a red card after a video review.
And while I am at it, if the referee is going to award a red card for Dempsey's arm swing, then where is the penalty kick for the defender grabbing Dempsey with both hands and impeding his progress in the box? What you say? He wasn't grabbed very hard, and the ball was played elsewhere? Maybe, but by the strict letter of the rule, that is a foul in the box and a penalty.
It seems to me the VAR can't have it both ways. Whether it is a red card for a flailing arm or a potential penalty, you either exercise some judgment as to the severity of the contact and the context in which it occurred, or you don't.
