This is red dog leader, I have a visual lock on an 8 ball. Moving in.

Tony Accardo used Giancana as a front.

But you're correct, when the Chicago Outfit pushed out "Cowboy" Benny Binion they took over Dallas Ft Worth. One of the first people sent from Chicago to run the new territory was Jack Rubenstein/Ruby.

JFK and father Joe made a deal with the outfit, at an in person meeting. In exchange for the outfit's support JFK agreed to the deal - DOJ would back off OC prosecutions. Joe was able to make this deal because Accardo, Giancana and the others were his former business partners, not just in bootlegging but a broad range of criminal activities.

JFK subsequently reneged on the deal. Went rogue for America, and knowing their was a high probabilty the outfit would take their traditional revenge. Assassination suited the intelligence agencies fine, JFK had fucked up their effort to regain Cuba for the mob.

JFK and RFK both knew the likely outcome for them betraying and prosecuting the mob, and they gave up their lives so that decades later America would Awaken.
