Summary: Louisville police killed Breonna Taylor during an execution of a "no-knock warrant" in her home. No one was charged for her death, but it changed the lives of the city's residents, spurring vast protests and calls to action. Despite some efforts, the city's Black residents are still awaiting systemic change. John Yang examines how segregation and historical redlining led to the current situation.
