Overview: Milwaukee is said to be one of the most racially divided and impoverished cities in the US. With spiraling gun crime and homicide rates, this Midwestern city encapsulates America's complex and troubled relationship with guns and the increasing disharmony between African-American communities and the police. In this episode, Louis spends time with the Milwaukee Police Department as they patrol District 5, home to some of the nation's deadliest streets, with a homicide rate over twelve times the national average, and follows the homicide division as they investigate one of the city's many killings. He also embeds with a family who have recently lost a loved one to gun crime, and he meets a local social activist, once a criminal and gang leader herself, who has turned her life around and is coming up with her own solution to the blight of gun crime. On the streets of Milwaukee, Louis discovers a community who is often misunderstood by, and mistrustful of, the police. Arriving at a time of heightened tension between the police and the African-American community due to a recent police shooting, Louis hears from both sides of the debate and uncovers hope in a desperate city.
