I will say this, I do believe that Casso had both police and FBI on his payroll. Most of the 36 he killed he most likely believed were informants. If all of that is true, it means there are people in the NYPD and FBI who are accessories to Casso's 36 murders, and they look like clean upstanding citizens.
