Many years ago, I watched a TV chat show with the late Quentin Crisp, a most interesting man on many levels (he is the subject of Sting's 1987 song "An Englishman In New York"). During the show, Crisp launched into a monologue where he lamented what he saw as the lack of style in modern crime. His view was that what he called "white collar crime" was so much less glamorous than breaking the bank at Monte Carlo or robbing banks. He may have had a point about the lack of style, but according to a recent study, bank robbery no longer rates as a useful form of robbery. The RoI is poor, very poor.
