Following the 1967 wave of urban uprisings in Black communities, President Lyndon Johnson established the National Advisory Commission on Civil Disorders to investigate “What happened? Why did it happen? What can be done to prevent it from happening again and again?” As part of the relatively small field of social science on rioting, it is best known for its alarming statement that “Our nation is moving toward two societies, one black, one white—separate and unequal,” a dire prospect for a country that had dismantled the legal doctrine of “separate but equal” just a dozen years before.

Less often quoted is the Commission’s in-depth study of the nature and process of rioting. Altogether, Malcolm McLaughlin records in a recent book (Long, Hot Summer of 1967: Urban Rebellion in America), in the first nine months of 1967, “almost 170 cities in 34 states and the District of Columbia had experienced an uprising of some sort, and almost 40 communities had more than one. Few corners of urban America were left untouched.” In its effort to document and understand the riots, Kerner Commission reached the following conclusions, many of which seem very descriptive of the past year’s flashpoints of unrest from Ferguson, Missouri to Baltimore, Maryland.

The “typical” riot did not take place. The disorders of 1967 were unusual, irregular, complex and unpredictable social processes. Like most human events, they did not unfold in an orderly sequence. However, an analysis of our survey information leads to some conclusions about the riot process.

In general:

The civil disorders of 1967 involved Negroes acting against local symbols of white American society, authority and property in Negro neighborhoods—rather than against white persons.

Of 164 disorders reported during the first nine months of 1967, eight (5 percent) were major in terms of violence and damage; 33 (20 percent) were serious but not major; 123 (75 percent) were minor and undoubtedly would not have received national attention as “riots” had the nation not been sensitized by the more serous outbreaks.

In the 75 disorders studied by a Senate subcommittee, 83 deaths were reported. Eighty-two percent of the deaths and more than half the injuries occurred in Newark and Detroit. About 10 percent of the dead and 38 percent of the injured were public employees, primarily law officers and firemen. The overwhelming majority of the persons killed or injured in all the disorders were Negro civilians.

Initial damage estimates were greatly exaggerated. In Detroit, newspaper damage estimates at first ranged from $200 million to $500 million; the highest recent estimate is $45 million. In Newark, early estimates ranged from $15 to $25 million. A month later damage was estimated at $10.2 million, over 80 percent in inventory losses.

In the 24 disorders in 23 cities which we surveyed:

The final incident before the outbreak of disorder, and the initial violence itself, generally took place in the evening or at night at a place in which it was normal for many people to be on the streets.

Violence usually occurred almost immediately following the occurrence of the final precipitating incident, and then escalated rapidly. With but few exceptions, violence subsided during the day, and flared rapidly again at night. The night-day cycles continued through the early period of the major disorders.

Disorder generally began with rock and bottle throwing and window breaking. Once store windows were broken, looting usually followed.

Disorder did not erupt as a result of a single “triggering” or “precipitating” incident. Instead, it was generated out of an increasingly disturbed social atmosphere, in which typically a series of tension-heightening incidents over a period of weeks or months became linked in the minds of many in the Negro community with a reservoir of underlying grievances. At some point in the mounting tension, a further incident—in itself often routine or trivial—became the breaking point and the tension spilled over into violence.

“Prior” incidents, which increased tensions and ultimately led to violence, were police actions in almost half the cases; police actions were “final” incidents before the outbreak of violence in 12 of the 24 surveyed disorders.

The typical rioter was a teenager or young adult, a lifelong resident of the city in which he rioted, a high school dropout; he was, nevertheless, somewhat better educated than his nonrioting Negro neighbor, and was usually underemployed or employed in a menial job. He was proud of his race, extremely hostile to both whites and middle-class Negroes and, although informed about politics, highly distrustful of the political system.

A Detroit survey revealed that approximately 11 percent of the total residents of two riot areas admitted participation in the rioting, 20 to 25 percent identified themselves as “bystanders,” over 16 percent identified themselves as “counter-rioters” who urged rioters to “cool it,” and the remaining 48 to 53 percent said they were at home or elsewhere and did not participate. In a survey of Negro males between the ages of 15 and 35 residing in the disturbance area in Newark, about 45 percent identified themselves as rioters, and about 55 percent as “noninvolved.”

Most rioters were young Negro males. Nearly 53 percent of arrestees were between 15 and 24 years of age; nearly 81 percent between 15 and 35.

In Detroit and Newark about 74 percent of the rioters were brought up in the North. In contrast, of the noninvolved, 36 percent in Detroit and 52 percent in Newark were brought up in the North.

What the rioters appeared to be seeking was fuller participation in the social order and the material benefits enjoyed by the majority of American citizens. Rather than rejecting the American system, they were anxious to obtain a place for themselves in it.

Numerous Negro counter-rioters walked the streets urging rioters to “cool it.” The typical counter-rioter was better educated and had higher income than either the rioter or the noninvolved.

The proportion of Negroes in local government was substantially smaller than the Negro proportion of population. Only three of the 20 cities studied had more than one Negro legislator; none had ever had a Negro mayor or city manager. In only four cities did Negroes hold other important policy-making positions or serve as heads of municipal departments.

Although almost all cities had some sort of formal grievance mechanism for handling citizen complaints, this typically was regarded by Negroes as ineffective and was generally ignored.

Although specific grievances varied from city to city, at least 12 deeply held grievances can be identified and ranked into three levels of relative intensity:

First Level of Intensity
1. Police practices
2. Unemployment and underemployment
3. Inadequate housing

Second Level of Intensity
4. Inadequate education
5. Poor recreation facilities and programs
6. Ineffectiveness of the political structure and grievance mechanisms.

Third Level of Intensity
7. Disrespectful white attitudes
8. Discriminatory administration of justice
9. Inadequacy of federal programs
10. Inadequacy of municipal services
11. Discriminatory consumer and credit practices
12. Inadequate welfare programs

…

Social and economic conditions in the riot cities constituted a clear pattern of severe disadvantage for Negroes compared with whites, whether the Negroes lived in the area where the riot took place or outside it. Negroes had completed fewer years of education and fewer had attended high school. Negroes were twice as likely to be unemployed and three times as likely to be in unskilled and service jobs. Negroes averaged 70 percent of the income earned by whites and were more than twice as likely to be living in poverty. Although housing cost Negroes relatively more, they had worse housing—three times as likely to be overcrowded and substandard. When compared to white suburbs, the relative disadvantage is even more pronounced.

A study of the aftermath of disorder leads to disturbing conclusions. We find that, despite the institution of some post-riot programs:

Little basic change in the conditions underlying the outbreak of disorder has taken place. Actions to ameliorate Negro grievances have been limited and sporadic; with but few exceptions, they have not significantly reduced tensions.

In several cities, the principal official response has been to train and equip the police with more sophisticated weapons.
