Conspiracy theorists have kept alive the theory that George Jackson was murdered. There is no proof to substantiate this claim, and not reason a prison guard would have colluded with the government for a murder cover up. George Jackson tried to escape San Quentin, and in working to protect the prison, was killed by a guard.
George Jackson changed his will three days before his death. He was to stand trial for murdering a prison guard, but was killed while attempting to escape a week before the trial. There are conspiracy theories that the escape was a setup by the government or by Jackson's rivals in the Black Panthers. It doesn't matter--his pointless death served as a martyrdom for the movement, even though the Black Panthers were waning in their influence at the time of Jackson's death.
No,the murder of George Jackson was not meant to deter future would be Black Panthers.Because the Black Panthers are a radical organization the death of a leader would more than likely be an incentive than a deterrent because the leader would be seen as a martyr for the stated cause.
This man made a whole lot of white Americans mad at him because of his racist actions, and a lot of blacks were also mad because he even made matters worse for them. There was not a government plan to kill this man, but just a mad citizen ending trouble.
I believe it is unreasonable to assume that George Jackson was murdered in San Quentin as a secret governmental activity designed to deter future would-be Black Panthers. According to reports he snuck in a weapon and essentially tried to take over the prison. He was shot in the yard in what seemed to be an escape plan. Saying it was anything else is just supporting a conspiracy theory.
