I supported the execution, because justice must be done on vicious murderers. But I don't think the law says anything about dishonoring the body of an executed criminal. I believe the usual procedure is to turn the dead body over to the next to kin, to give it whatever kind of funeral ceremony they see fit. If there are no next of kin, then it depends on his last will and testament, statements he made before the execution, or the best judgment of the authorities as to who represents him or is closest to him.
Let Hollywood and the Crips give him a fancy funeral if they like. I think it will be about as useful for their propaganda purposes as Paul Wellstone's funeral. In other words, most people will see it as grotesque, and it will backfire against any stars who participate in it.
When somebody wants to make a fool of themselves, get out of the way and let them. I agree.
