alt Hacker NewsNYC has a markedly more pronounced history with organized crime - including that extant sort which is associated with the financial industry - and the municipal culture that develops to deal with it. Of course, this implies that now that Dallas is getting a stock exchange, your claim might become salient in a decade or two.
Emphasis on history: NYC very famously broke its organized crime groups in the 1980s and 1990s. It's what made Giuliani famous before he became a politician[1].
(I would hazard a demographic claim around organized crime: just about any mid-sized city with large suburbs almost certainly has more per-capita organized crime than NYC does. You just don't hear about it because most of it is of the "extortion for trash pickup" variety, not the "Murder, Inc." variety.)
