Thanks again @BlackFam for the great info.

Still cant believe the cash which those guys made during those days ONLY from gambling and policy, and if we also include their income from bootlegging, prostitution and narcotics, they were obviously billionares. The Outfits street tax was probably "nickles and dimes" for the black racketeers at the time, which was probably the main reason for the long and peaceful collaboration between the two ethnic crime groups.

Also, the Loop and South Side were probably the main areas regarding the previous peaceful collaboration between the syndicates, hence the close connections of the so-called Outfit southsiders like Guzik, Hunt, Alex and Pierce with the black racketeers. As we already know, later Giancana, Volpe and Campagna from the West Side realized that they were able to get more money with the help of brutal force, instead of receiving only street tax.

Ive seen Dan Jackson's name in more than few articles from the old days and it seems he was one of the prime players, as you already stated. Also, I always wondered on whether the black syndicates who were loyal to the Outfit had some involvement in the whole corruption regarding the St. Valentines Day massacre, mainly because of their political and criminal contacts around the Midwest?!

Btw, here are few interesting articles from the 1920s.....
