Transcript Thoko Moyo: The video of the brutal killing at the end of May of George Floyd by Minneapolis police has pushed America to another major inflection point in a seemingly endless struggle with race. Hundreds of thousands of Americans and others around the world have taken to the streets to decry police violence, racism, and to demand change. America has a history of systemic racism, which goes back 400 years, and the cycle of injustice, protest, riots, inadequate reaction and response has come around many times in the US since the 60s.

I'm joined by Harvard Kennedy School professors, Khalil Muhammad and Erica Chenoweth.
