On Sunday, police officers in Seattle shot and killed Charleena Lyles in her home. She died in front of “several children,” according to reports, and her family members say she was pregnant. Just days before, Jeronimo Yanez, the Minnesota police officer who shot and killed Philando Castile during a traffic stop, was acquitted of all charges. Earlier this spring, an unarmed teenager named Jordan Edwards was shot and killed by police as he was driving away from a party. By now, it’s become a sickeningly familiar sequence of events.
