Other officials drew similar conclusions, despite discovering and citing facts that disproved their thesis. Dr. Lowell S. Selling of the Recorder's Court Psychiatric Clinic conducted interviews with 100 black offenders. He found them to be "employed, well-paid, longstanding (of at least 10 years) residents of the city", with some education and a history of being law abiding. He attributed their violence to their Southern heritage. This view was repeated in a separate study by Elmer R. Akers and Vernon Fox, sociologist and psychologist, respectively, at the State Prison of Southern Michigan. Although most of the black men they studied had jobs and had been in Detroit an average of more than 10 years, Akers and Fox characterized them as unskilled and unsettled; they stressed the men's Southern heritage as predisposing them to violence. Additionally, a commission was established to determine the cause of the riot, despite the obvious and unequal amount of violence toward blacks. Later, it was found that the commission was extremely biased; it blamed the riot on blacks and their community leaders.
