 As an informant, Johnson did not seek, as many do, intervention by the FBI to get criminal charges reduced or dropped, aside from the aforementioned counterfeiting charges.During his 16 years as an informant, Johnson provided information on all the different New York Mafia crews that he worked with, and the FBI used that information to make many arrests.However, as his FBI handler, Special Agent Martin Boland, noticed, Johnson refused to discuss his background or childhood in any detail.
