L.A. Heat - Season 2 Episode 3 Burning Sanctuary

A group of Nazi skinheads demonstrate outside a black church, and a riot is narrowly prevented as Chase and August arrest a skinhead and a churchgoer. The next week, the church is burned to the ground, and a charred body is found inside - Duke Minks, a member of the Aryan Nation, who was arrested during the demonstration. The victim's uncle, Eddie Minks, also a member of the Aryan Nation, isn't happy that August is on the case, and warns that justice will be served, one way or the other. As the detectives dig deeper, they learn that the arsonist may be the person they least suspect.
