Hundreds of people are killed by police in the US each year, and much attention has been paid recently to the high proportion that are black. But there's another disturbing trend that is rarely discussed.
It was shortly after 05:00 when three West Milwaukee police officers broke into the home of 22-year-old Adam Trammell to find him naked and bewildered, standing in his bathtub as water from the shower ran down his body.
Adam, who had been diagnosed with schizophrenia, was having some form of breakdown. A neighbour had called 911 to report that she had seen him naked in the corridor, talking about the devil. She thought Adam's name was Brandon, and told police this when they arrived at the building.
According to his father, Larry Trammell, Adam often had delusions and hallucinations. He would take showers to help him calm down when he felt anxious.
Adam was not armed and he did not appear to behave in a threatening manner. But he did not leave the shower as the police commanded.
