Defense systematically attacked police procedures and evidence handling throughout the day, with four key officers and a criminalist testifying about their actions at the Bundy and Rockingham scenes on June 13, 1994. Cross-examination focused on contamination risks—Thompson's lack of protective gear, travel between scenes, and the absence of thorough documentation—while establishing that Detective Fuhrman was alone for 5-7 minutes before announcing he found the incriminating glove at Rockingham. A prior impeachment of Detective Phillips on Simpson's actual response to the death notification strengthened the defense narrative that police testimony was unreliable.

• Officer Thompson testified he entered the victim's residence without protective gear and handled a blanket without inspection before using it at the crime scene, establishing contamination risk
• Detective Phillips was impeached by his own written report, which contradicted his direct testimony about what Simpson said when notified of Nicole's death
• Defense established that Fuhrman was unsupervised for 5-7 minutes before discovering the critical Rockingham glove
• Multiple witnesses testified about blood at Bundy rear gate and Rockingham, with defense emphasizing gaps in documentation and photography
• Jury and counsel stipulated that sunrise was 5:42 AM on June 13, 1994, establishing timeline constraints
