The reputed gangsters argued the feds wrongly targeted them because of their Italian heritage. The government’s case relied heavily on two cooperating witnesses — Peter Lovaglio and Stephen Sabella — who seemed more loathsome than the men on trial. Lovaglio, whose nickname is “Petey BS,” testified he hit a retired police officer with a glass in Staten Island, partially blinding him. Sabella confessed to posting racial and homophobic comments on Zancocchio’s granddaughter’s Facebook page weeks before the trial began.
