Most of what you know about the Black Panthers, is a lie. It is intentional disinformation, created and circulated by the FBI, with the assistance and complicity of newspapers and local police. This disinfo was spread as part of the FBI's counter intelligence program (COINTELPRO).
This is not some unfounded conspiracy, this is documented and now admitted by the FBI.
The Black Panthers were the good guys, and the FBI were the cartoonishly evil Bond villain bad guys. Seriously.
