One of his most high-profile accomplishments was a lawsuit to obtain information about racial profiling in Rudy Giuliani's police force. As Green told the "Gotham Gazette", "We sued Mayor Giuliani because he was in deep denial about racial profiling. winning the case, we released an investigation showing a pattern of unpunished misconduct ... the rate that police with substantiated complaints are punished went from 25 percent to 75 percent." Green was reportedly one of the first public officials to draw attention to racial profiling by the NYPD.
