**URGENT** IWA HELP REALLY NEEDED

Can someone give me advice on my research question: How does unconscious racial bias among judges and law enforcement impact the fairness of the criminal justice system?

Also, would Eloise Cobell: A Small Measure of Justice work to support my research question because I was planning on using it but I realized that it would be too confusing for me to find evidence in the source to help support my argument since it doesn't discuss a lot of information that would help connect to my question, so is Confrontation on the bridge a better source?
