You're comparing a guy who was acquitted of his charges to a guy who was convicted.
This is a pathetic argument. Everyone knew that OJ was guilty. He murdered Nicole Brown Simpson and Ronald Goldman in cold blood and never got the deserved punishment. He walked free, as he was rich and influential. In the United States, rich people who commit murder very rarely go to prison. The same happened with OJ as well.
I guess 'everyone knew he was guilty' except the jury. So again, you're comparing a guy who was acquitted of his charges to a guy who was convicted. The analogy is as worthless now as the first time you said it because you're trying to draw a conclusion about how one guy got punished by society for his crimes vs. a guy who society decided committed no crime. I'm also certain OJ committed murder, but it doesn't make the analogy any more relevant, because you're not comparing two like things.
