In real life, no branch of the US government would make a deal with anyone that recruits terrorists. JR and Bobby would definitely have gone to prison.
For some reason, only JR and Bobby face prison time and other extensive consequences for the BD Calhoun affair. Other co-owners of Ewing Oil, such as Miss Ellie, Ray, and Cliff Barnes (since he owns 5% after Jamie's death) are never implicated nor seem concerned about the same consequences, except for Ray when he confronts JR about it.
