Robert Groden served as the defense's photographic expert, brought in to challenge the authenticity of photographs showing O.J. Simpson wearing Bruno Magli shoes at a 1993 football game. His testimony claimed anomalies in the images suggested forgery, but his credibility unraveled under a extended cross-examination by plaintiff attorney Peter Gelblum, who exposed résumé inflation, lack of formal credentials, tabloid dealings, and methodological failures — ultimately demonstrating that the supposed anomalies appeared across multiple frames. When plaintiffs introduced 30 newly discovered photographs from the same game, Groden was forced to concede the additional images would affect his overall conclusion about forgery, and forensic expert Gerald Richards subsequently rebutted his claims point by point through microscopic analysis and precise measurement.
