Protests are nothing new in the United States. But it seems clear we still aren’t very good at determining how to deal with them. After the death of George Floyd in Minneapolis, protests began. They quickly turned violent, and police in Minneapolis tried a variety of tactics to deal with them. Initially, police backed off entirely, even as one of their precincts was torched. By Saturday, the police presence was much higher, as was their willingness to engage. Reporters were arrested live on camera, others were shot with rubber bullets. Those engaged in peaceful protests were pepper-sprayed. Other cities where protests broke out employed even different tactics. In New York, police drove their SUV into a crowd of people. In other cities, police chiefs and sheriffs marched along with protesters. But which of these police protocols are actually the most effective? Surely that has been studied from past protests. Shouldn’t there be some sort of playbook that outlines just how police should respond when protests begin, and how that should change when those protests turn violent. It seems that despite our nation’s long history of protests, peaceful and otherwise, we haven’t really learned a lot along the way.
