A homeless advocacy organization and a Black Lives Matter group are challenging the fatal Cincinnati police shooting of a black man with a history of mental illness.
The Hamilton County prosecutor called the shooting justified. The police chief said the white officer was under "vicious, violent attack" by a knife-wielding robbery suspect.
The Greater Cincinnati Homeless Coalition and Black Lives Matter Cincinnati have issued a joint statement saying Jawari Porter's death was avoidable. They say police escalated the Sunday confrontation.
Video released Monday shows the 25-year-old Porter lunging at an officer in the driver's seat of a police vehicle. Authorities say Porter was trying to stab him.
Court records show a judge last year found that Porter was mentally ill and incompetent to stand trial on assault charges. He was ordered into treatment.
