In summary, money talks and there is plenty of scum apologists (including people in this thread) out there who will argue his case because it didn't go to court.
For those that think he should be given the benefit of the doubt, do you really want your kids/grandkids growing up with a man who has abused a woman as a role model? Would you be happy to brush this abuse under the carpet if it was your wife/daughter/sister that had suffered this abuse?
Once again, the court of law is irrelevant - there is literally a video of the abuse. He IS guilty, there is no possible outcome that suggests he isn't. It sickens me that people are trying to find ways to justify him getting back into football.
