My own personal take about Roy Innis, and mind you, this is only conjecture. I think Innis Sr. was driven by jealousy that he could never attain the kind of leadership accolades that others in the movement were able to garner. It was almost palpable when you watched video or looked at group photos of him in the mix. The level of distain was too hard for him to hide. Each individual organization made a contribution in it’s own way. As was the case with the leader of each one.
Some names fell off the lips easier and quicker but his was hardly one of them. So, I think the progression to his ultimate path was probably inevitable. I always refer back to the adage…what you put out, you get back.
