In our new VICELAND series Black Market, actor Michael K. Williams meets society's outcasts—from New Jersey's carjackers to animal poachers in South Africa to stick-up boys in Brooklyn to London's heroin-addicted shoplifters. The show offers a rare look into the lives of people driven by desperation to work in underworld economies.On the next episode, Williams investigates America's illicit gunrunning business. He sits down with a group of Atlanta dealers who transport cheap illegal weapons up to New York, where they sell them, often to gangs. Williams discusses the violent implications this underground economy has on black lives, and why the dealers feel like they have no viable alternative.Watch the clip above and make sure to catch the show every Tuesday night at 10 PM on VICELAND.
