In 1968, FBI Director J. Edgar Hoover said the Black Panther Party "without question, represents the greatest threat to the internal security of the country." And with that declaration he used United States federal law enforcement to wage war on the group. But why did Hoover's FBI target the Black Panther Party more severely than any other Black power organization? Historian Donna Murch says the answer lies in the Panthers' political agenda: not their brash, gun-toting public image, but in their capacity to organize across racial and class lines. It was a strategy that challenged the very foundations of American society. And it was working.
