Mob Informant Had Power And A Wire

How the mob got caught:

Mr. Joseph Vollaro, who had already been netted in a drug sting by the State Organized Crime Task Force, had agreed to become a government witness. He wore a hidden recording device and captured his conversations with a range of accused mobsters, including Mr. Corozzo.

So it appears that it was actually the Task Force, federal prosecutors and the F.B.I. who were stringing Mr. Corozzo along, gauging his sincerity to try to determine whether he indeed intended to induct their informant into the family, a ceremony some among them were keen to record for posterity.
