Unfortunately, it is you who has it backwards. Tell me, did the rise of the mafia gangs (Al Capone, etc.) occur before, or after the enactment of the XVIII Amendment? And did the violence end and the gangs find more peaceful pursuits before or after the enactment of the XXI Amendment? Are you aware of the chronology of the rise of the Asian and South American gangs in the latter part of the 20th Century?
