Four years into the first black presidency in US history, Baltimore's inner-city neighborhoods are still living inside the drug war that Washington now admits it is losing. Al Jazeera's Fault Lines correspondent Sebastian Walker spends time with residents, police, and addicts on the streets of one of the country's most violent cities, tracing how decades of drug enforcement reshaped race, poverty, and incarceration in America. Ed Burns, a former Baltimore homicide detective turned co-creator of The Wire, argues on camera that the war on drugs was never really about drugs: he calls it a deliberate effort to dismantle the energy of the civil rights movement, first aimed at black communities and later extended to Hispanics and poor whites. The film catches Baltimore police mid-rebrand, retiring the language of a 'war on drugs' for a 'war on guns' even as arrests and incarceration rates keep climbing. White House officials float a shift toward public health policy, but on Baltimore's corners that shift has not yet arrived.
