It's the battle of the experts in this phase of the trial. Defense DNA experts criticize the police lab technicians "sloppy" work and accuse them of epidemically contaminating evidence. Blood spatter expert Herbert MacDonnell testifies about "wet transfer stains" saying the sock stains were consistent with someone dabbing the sock in blood when Simpson was not wearing it. The infamous "Fuhrman Tapes" are discussed outside the presence of the jury. The videotapes are said to feature Detective Mark Fuhrman allegedly using the n-word and describes L.A. police officers fabricating evidence and harassing African Americans, among many other racist actions.
