It's also available on archive.org, if anyone wants to download it here (this one's in english) or to watch after this link expires, the dafilms version is higher quality.
Also found this from the film "Huey" by the same director. More on the Black Panther party during the same period, in B&W.
Thanks for the link beezneez!
If anyone is interested in sharing another film from here that isn't free, I'd gladly pay for it so we can all share!
EDIT!: so apparently the first link I posted from archive.org is in french, but I found a rogue copy of the original film in English!
I uploaded to mediafire cause I don't really want to use my google drive, if anyone thinks I should upload it elsewhere (I'm planning on submitting it to archive), just let me know!
