[El Chinito loco]

What would prevent a wealthy criminal from purchasing his own "security" company or that of existing services and using it to control a piece of the city as his own personal fiefdom?

If I were a cashed up drug lord this is precisely the sort of thing i'd invest in or at least start up my own rival company. A whole professional militia ready to be bought and also getting the neighborhood to pay me personal "protection" money for my men to watch over them?
