 James There were always 'some' viciously pro-Castro persons in the 00 Of July Movement threatening and suspicious of other members who might betray the cause, moreso as the 'expected invasion' of Cuba drew near. Raul Roa had earlier exposed the 'entire' invasion scheme to the United Nations. Re; the FBI, Chicago, I only knew that Director Hoover made the Castro/Fair Play For Cuba Comm. et.al. top concern for the Bureau. I met with agents only at various pre-arranged places or via two way phone calls re; information, never at hdqrts. I would say it was the cointelpro{spelling} program?
