At the time, white commissions attributed the cause of the riot to black people and youths. But the NAACP claimed deeper causes: a shortage of affordable housing, discrimination in employment, lack of minority representation in the police, and white police brutality. A late 20th-century analysis of the rioters showed that the white rioters were younger and often unemployed (characteristics that the riot commissions had falsely attributed to blacks, despite evidence in front of them). If working, the whites often held semi-skilled or skilled positions. Whites traveled long distances across the city to join the first stage of the riot near the bridge to Belle Isle Park, and later some traveled in armed groups explicitly to attack the black neighborhood in Paradise Valley. The black participants were often older, established city residents, who in many cases had lived in the city for more than a decade. Many were married working men and were defending their homes and neighborhood against police and white rioters. They also looted and destroyed white-owned property in their neighborhood.
