Who is John Grambling from Without Conscience: The Disturbing World of the Psychopaths Among Us and what is their importance?

Grambling's case study is an example of white collar crime. With the help of an accomplice, Grambling conned many banks into handing over millions of dollars. Without a gun, the two men walked away with 36.5 million dollars. They impressed people with their appearances and finessed bank owners with their charms. Grambling is an example how psychopaths with societal connections and friends can con people without violence.
