F. Lee Bailey served as a defense attorney whose central contribution was his relentless, multi-day cross-examination of Detective Mark Fuhrman — methodically attacking the detective's credibility by exposing inconsistencies in his account of finding the Rockingham glove, his numerous pre-testimony coaching sessions with prosecutors, and pressing him on whether he had ever used racial slurs, which Fuhrman categorically denied under oath. Beyond Fuhrman, Bailey conducted aggressive cross-examinations of FBI experts Douglas Deedrick and William Bodziak, establishing critical gaps in the prosecution's forensic case, including the absence of Simpson's hair at the crime scene and challenges to the "two trips" theory. He was a persistent presence across dozens of proceedings — from early motions on domestic violence evidence admissibility, where he sparred with prosecution psychologist Dr. Donald Dutton, to cross-examinations of LAPD officers like Sergeant Rossi that exposed systemic failures in evidence preservation and a false crime scene log entry.
