FBI surveillance bugs placed in the garage of reputed Gambino mobster Michael Scandifia revealed conversations about mob hits and even a scheme linked to an NYPD Patrolman. Leonard Grossman was employed by the New York Police Department starting in 1950. Taped evidence revealed that Grossman and Scandifia planned to use dumdum bullets to murder informants who testified against the Mafia. A cooperative neighbor in the Coney Island neighborhood near Scandifia's garage agreed for a bugging device to be installed in his basement.
