this is how the feds treat you. You help them and they stab you later. Luciano’s contacts in Sicily were the ones communicating with the US Army before Patton and Monty landed.
In all fairness Lucky was quietly released and deported to Sicily after the war. Probably as good a deal as he could have hoped for.
I’ve read that any American soldier on Sicily could invoke the Luciano name and be treated like royalty by the locals. Good food, wine and...umm..hugs and kisses from the ladies.
The Luciano name carried some heavy weight.
