The defense challenged Detective Mark Fuhrman's credibility through testimony from three witnesses about racist statements. Kathleen Bell and Natalie Singer described statements attributed to Fuhrman from 1985-1987, while filmmaker Laura Hart McKinny testified that Fuhrman used a racial slur approximately 42 times in recorded interviews and authenticated recordings played for the jury. William Blasini testified that he saw no blood while looking through OJ Simpson's Bronco during a June 21 inspection, although cross-examination established that he could not say blood was absent. Photographer Rolf Rokahr established the sequence of the glove photographs but could not reliably determine their timing. The prosecution challenged Singer, Blasini, and Rokahr and argued against further cumulative Fuhrman testimony.

• Kathleen Bell testified that Fuhrman made openly racist statements in 1985-86, including wishing Black people could be 'gathered together and burned'
• Natalie Singer testified that Fuhrman used racial slurs and said 'the only good Nigger is a dead Nigger' during a 1987 encounter
• William Blasini testified that he saw no blood while looking through the Bronco on June 21, 1994, but conceded on cross-examination that he could not say blood was absent
• Rolf Rokahr established that the glove photographs were frames 34-35—the final shots on the first film roll—but testified that he could not reliably determine when individual photographs were taken
• Laura Hart McKinny presented recorded interviews documenting Fuhrman using racial slurs approximately 42 times across a decade of conversations
• Audio recordings of Fuhrman himself using racial epithets were played for the jury
• Prosecutor Darden made an emotional plea asking the court to halt Fuhrman testimony and refocus on OJ Simpson
