tavis: let me ask one that remains unconsideranswered and these crimes lead to new laws, did anything good happen out of the o.j. simpson case? >> if anything good happened, it didn't offset the evil, i don't think. we did have an occasion to ask ourselves a lot of serious issues. is a person that is successful and well off and a sports superstar, is he still a victim of racism? where does his anger come from? also we learned from that case putting cameras in a courtroom is still dangerous, we learned that in a previous case that that no one knows they are there. but the people on stage do. and that's another lesson we took from that. tavis: speaking of cases that have gone over and over and anything to learn from james and vis-a-vis and others? >> i have read about two crime books and there are two about the kennedy assassination i recommend. one is jerald cosmer's case closed that reviews the theories that float around. another book by menninger that explains the theories of a baltimore man, donahue. that book is not easy to read but if there is a flaw in his thesis, i don't see it.
