The most recognizable symbol of solidarity with today's movement against racism and police brutality has been to take a knee, an act of protest popularized by Colin Kaepernick. He's the latest in a long line of athlete-activists whose outspoken defiance have helped push forward social and political change in America.

Our host Varun Soni explores these questions and more in conversation with Jody Armour, professor of law and author of the upcoming book, "N*gga Theory: Race, Language, Unequal Justice and the Law."
