If Empire Bay is fictional New York ( or basically any east coast city would prove my point) how so there are triads selling heroin? Heroin from golden triangle was smuggled via West Coast harbors. New York recieved heroin from European and Middle eastern suppliers who would not stand Triads as their competition. Am I wrong or is there any fact that I am missing?
