His name was Paul Castaway, a schizophrenic man of the Rosebud Sioux Tribe. Police shot him four times. They say he was running at them with a knife but witnesses and video footage say he was walking toward them with a knife held at his own throat. Police say they came because he stabbed his mother in the neck. His mother says he poked her in the neck with a knife and she asked police to come help her subdue him. She now regrets making the call.
Most news outlets I looked at can't help but list his criminal record. Only one listed his tribal affiliation.
Police brutality against Native American people is also a huge problem. No one seems to care. I only saw one post about this on Tumblr. He will get no justice.
