That was a time when many black men like Carter were supposedly railroaded into jail. At least many white libs like Dylan swallowed those stories. I read Carter’s ghostwritten bio, which contained a number of stories of which I was extremely skeptical as to their veracity. I don’t know for sure if he did the crime he was put in prison for or not, but he was a violent person in and out of the ring.
That was the time of "radical chic" (about the time of "porno chic") when wealthy liberals would throw house parties and fundraise for known seditious and terrorist groups.
