Miles Hall, a 23-year-old Black man experiencing a psychotic episode, was shot and killed by police after 911 received calls of a disturbance in his Walnut Creek, California neighborhood. His mother Taun Hall had taken steps to warn the local police that her son had been diagnosed with schizoaffective disorder and that he might be prone to mental health crises. She believed she had done enough to ensure that, in the event of a crisis, her son would be treated with care. But when the crisis came, authorities viewed Miles’ behavior through the lens of public safety, not through the lens of mental health, and it cost him his life.
