From Wikipedia
In April 1977 Panthers were key supporters of the 504 Sit-ins, the longest of which was the 25-day occupation of the San Francisco Federal Building by over 120 people with disabilities. Panthers provided daily home-cooked meals in support of the protest’s eventual success, which eventually led to the Americans with Disabilities Act (ADA)thirteen years later.
The Black Panthers were heroes. Armed minorities are harder to oppress, and they make ALL of us harder to oppress.
