How does the race of protesters affect how police respond to protest events? Drawing on the protest policing literature and on theories of race and ethnic relations, we explore the idea that police view African American protesters as especially threatening and that this threat leads to a greater probability of policing. We examine more than 15,000 protest events that took place in the United States between 1960 and 1990 and find that in many years, African American protest events are more likely than white protest events to draw police presence and that once at events, police are more likely to take action at African American protest events. Additional analyses complicate these findings by showing that they vary over time. In many years, for example, African American protest events are no more likely than white protest events to be policed. While there is support for a “Protesting While Black” phenomenon, it is not invariant across the entire period of inquiry.
