While scholars typically treat violent protests as deliberate acts undertaken in V pursuit of specific goals, due to a lack of appropriate data and difficulty in causal identification, there is scant evidence of whether riots can actually increase support for these goals. Using geocoded data, we analyze measures of policy support before and after the 1992 Los Angeles riot—one of the most high-profile events of political violence in recent American history—that occurred just prior to an election. Contrary to some expectations from the academic literature and the popular press, we find that the riot caused a marked liberal shift in policy support at the polls. Investigating the sources of this shift, we find that it was likely the result of increased mobilization of both African American and white voters. Remarkably, this mobilization endures over a decade later. https://www.cambridge.org/core/terms iots are political acts in which participants en- around the world, the subject of political violence has en- Rgage in violence to express grievances and at- during importance.1 tempt to spur policy change.

Few studies have examined the localized effectiveness POLITICAL VIOLENCE AND PUBLIC POLICY of a riot, rather than treating the events as part of a larger phenomenon (e.g., Western 2006). While this By examining how a riot affected support for public broader focus can be valuable, it might mask differ- goods allocation, our study addresses the effectiveness ences between local and distal effects: for example, of rioting as a political activity. In doing so, we broaden https://doi.org/10.1017/S0003055419000340 while the consensus in the literature that a riot makes . our understanding of how political activity may con- citizens unsympathetic to the rioters may be accurate tribute to policy change, a question that typically on a national scale, local opinion may become more examines more common political behaviors, such as sympathetic because of shared identity, special voting, lobbying, or nonviolent protest. While such knowledge of local circumstances, or fear of further activities are often argued to be ineffective, especially unrest. Additionally, examining the effects of a riot on for low-status groups (Gilens 2012) such as poor African national-level opinion, while potentially important, Americans, we show that violent protest is an arguably overlooks that much policy, especially in the domains efficacious political activity, insofar as it changes local 2 of welfare and education, is controlled at the local or policy support. state level. Not everyone views rioting as politically motivated https://www.cambridge.org/core/terms and not all riot participants have the same motivations. However, social scientists often view rioting as a po- litical act (e.g., Huntington 1968) and classic studies of THE 1992 LOS ANGELES RIOTS riots show that participant aims include demanding On March 3, 1991, four white Los Angeles police redress for political grievances (Sears and McConahay officers were videotaped beating an African American 1973).
