Any Detroit experts know how strong they were from the 30s - 60s? We all know the Teamsters connections, labor connections, auto connections but they were so underground I don't think the average poster is familiar with all their made men (like they would be with Lucchese, etc).

How did the narcotics trade work back then? It seems like each family had one member who was HUGE in drugs and the rank and file soldiers were dissuaded under penalty of death from dealing.
