Four years after Michael Brown was shot to death by a police officer in Ferguson, Mo., young people of color are still dying. Still, as a panel discussion at the John F. Kennedy Jr. Forum noted on Monday, a movement has grown at the same time.

With a new documentary shedding light on Brown’s life and the subsequent Black Lives Matter movement, the national focus has turned to basic human and Civil Rights issues broached by his death — and the killings of Trayvon Martin, Stephon Clark, Philando Castile, and others — that society is being called on to tackle.

The Institute of Politics (IOP) panel discussion followed a screening of that documentary, “Stranger Fruit,” by filmmaker Jason Pollock. Pollock was joined by Benjamin Crump, attorney for the families of Brown, Martin, and Clark; Lezley McSpadden, Brown’s mother; and Jasmine Reed, attorney for the families of Brown and Martin.

The discussion was moderated by Khalil Muhammad, professor of history, race, and public policy at the Kennedy School (HKS), and Ashley Spillane, Roy and Lila Ash Student Fellow, Ash Center for Democratic Governance and Innovation, which co-sponsored the event with the HKS Black Student Union, HKS Arts and Culture Caucus, and the IOP’s Politics of Race and Ethnicity program.

The documentary, explained Pollock, began when he moved to Ferguson after hearing what had happened to Brown. Coming from Los Angeles, he said, “I didn’t see anyone talking about the case of Mike Brown, and that felt like the most important thing.”

Once he began to work on the film in 2013, its story deepened. “We wanted to show more of the context of what was happening in Ferguson,” said Pollack. “We talked a lot about the city of St. Louis,” where the so-called “race riots” of 1917 resulted in the deaths of more than 40 people of color, and possibly many more.

“Our country was built on genocide and slavery,” he said.

Reed said the film “did an incredible job of bringing you critical evidence of evidence that was concealed from the general public.”

“We are hoping it will change the hearts of people,” said McSpadden.
