How is it that the US government can eliminate the Black Panthers but are clueless as to how to eradicate the kkk?

I was fortunate to have watched this documentary at the library in downtown Nashville Tennessee with the filmmaker STANLEY NELSON and a small audience of roughly 75 people.  Little did I know that several members of the Black Panther Party were also in attendance and they took our questions and elaborated on areas of the film.  It was truly a life-changing experience... definitely, a must-see!

In the turbulent 1960s, change was coming to America and the fault lines could no longer be ignored — cities were burning, Vietnam was exploding, and disputes raged over equality and civil rights. A new revolutionary culture was emerging and it sought to drastically transform the system. The Black Panther Party for Self-Defense would, for a short time, put itself at the vanguard of that change.  The Black Panthers: Vanguard of the Revolution is the first feature-length documentary to explore the Black Panther Party, its significance to the broader American culture, it's cultural and political awakening for black people, and the painful lessons wrought when a movement derails.
