Source? That seems untrue, because those things are not necessarily connected to police incidents.....as well as other sources, such as hospital admissions, outreach workers, etc.
For example, let's say that the police admit a black person to a hospital. Is this automatically marked as "police brutality"? Why?
If black people are admitted to hospitals by police at a higher percentage than white people, does this mean that the police are the cause of their injuries, and that their injuries aren't justified? Or does this just mean that black people are resisting arrest more and committing more violent crimes that deserve an appropriately violent response?
