Another chart from the Real Deal Forum. Made by MobFan. Each Jewish mob organization was small in numbers, but they didn't care as long as they had the backing of the Italians. The modern day Jewish Mafia is the Jewish-Russian Mafia (aka Organizatsiya) in the Brighton Beach neighborhood of Brooklyn.
