Very little wrong with it. You are not comparing like with like. A better comparison would be the Kobi Bryant situation. What should have been done there? Bear on mind, Greenwood has been found guilty of nothing. His girlfriend remains in a relationship with him. Are you a party to that relationship?
My biggest issue is actually nothing to do with Mason Greenwood, who may well be a complete shithouse. It is the nature of modern society whereby public opinion seeks to usurp the judicial system. If the guy did it, he should be prosecuted and jailed if found guilty. He hasn’t been prosecuted and as such should be free to go about his life without the court of public opinion determining what should happen.
