In the trial's opening statements on September 25, Gotti's defense attorney Bruce Cutler denied the existence of the Gambino family and framed the government's entire effort as a personal vendetta. His main defense strategy during the prosecution was to attack the credibility of prosecutor Diane Giacalone's witnesses by discussing their crimes committed before their turning state's evidence. During Gotti's defense, Cutler called bank robber Matthew Traynor, a would-be prosecution witness dropped for unreliability, who testified that Giacalone offered him drugs and her underwear as a masturbation aid in exchange for his testimony; Traynor's allegations would be dismissed by Judge Nickerson as "wholly unbelievable" after the trial, and he was subsequently convicted of perjury.
