'The Black Panthers: Vanguard of the Revolution', an important, infuriating, stirring documentary

I caught the doc 'The Black Panthers: Vanguard of the Revolution' this past weekend, by director of 'Freedom Riders' Stanley Nelson.  The film provides excellent grounds for thinking about ongoing abuses of power on the one hand, and models of empowerment on the other. It features a comprehensive collection of archival material and beautiful profiles of the women and men at the helm of the movement. Days later I'm still thinking about it and looking up names and words such as the insidious FBI program COINTELPRO, which was behind the worst attacks on the Panthers. The screening was followed by a Q&A with Stanley Nelson and a former Panther, which could have gone on for days. As Stanley reminded us,  you could make a whole documentary series on the Panthers.
