To prevent this "Black Messiah" from rising, the FBI established a whole division to spread lies to tarnish the reputation *any* charismatic Black civil rights leader. This is why what most Americans know about the Black Panthers is so wildly different from the truth.
If the attempts to discredit the Black leader did not work, the FBI would create false arrests and false imprisonment. If that still did not work, assassination plans were drawn up.
Being a good leader could be a capital offense.
