When the police officers arrest Chad Higgins, the female officer is wielding a Beretta 92-type pistol, which is not one of the models authorized by the NYPD for use. (The male officer's sidearm is not clearly discernible.)
In addition to the captain's insignia on his collars, Captain Martin Savalas wears sergeant's stripes on his uniform's sleeves.
Captain Savalas' uniform has several errors. He is wearing the correct badge and collar insignia for a captain but he has sergeant's stripes on his arms. Plus he is wearing a black tunic, in the NYPD uniformed officers with the rank of lieutenant and higher wear white tunics.
