In this Art of the Cut special, we talk to Nels Bangerter, the editor of the revealing archival documentary "Riotsville, USA."

I last spoke to Nels on Art of the Cut for the release of another documentary "Dick Johnson is Dead." He's also edited documentaries including "Cameraperson," "Let the Fire Burn," "You See Me" and "32 Sounds." 

His work has been included on PBS Shows "POV" and on "Dan Rather Reports."
