The Oj Simpson 1994 murder case...?

I am currently doing a research paper on the the 1994 Oj Simpson murder case. I've done lots of research and it is very hard to believe Oj was let off the hook. There is one part of my paper that is very important and worth 70% of the grade. I need to come up with two "presentable, intelligent, and argumentative" questions i would ask the District Attorney and Tom Lange. There are many questions to ask but im having a hard time putting one together that is good enough. Please help! Thanks everyone!
