As the trial neared its end, J. Edgar Hoover branded the Black Panthers the greatest internal threat to American security. Earlier that year, the assassinations of Martin Luther King and Robert F. Kennedy rocked a nation already bitterly divided over the Vietnam War. As the jury deliberated Newton’s fate, America was a tinderbox waiting to explode.

At his trial, Newton and his maverick defense team led by Charles Garry and his then rare female co-counsel Fay Stender, defended the Panthers as a response to 400 years of racism and accused the policemen of racial profiling, insisting Newton had only acted in self-defense. Their unprecedented challenges to structural racism in the jury selection process were revolutionary and risky. If the Newton jury came back with the widely expected first degree murder verdict against the charismatic black militant, Newton would have faced the death penalty and national riots were anticipated. But Newton’s defense team redefined a “jury of one’s peers,” and a groundbreaking diverse jury headed by pioneering Black foreman David Harper delivered a shocking verdict that still reverberates today.
