Maybe the wide-spread police brutality seen in those protests can be better understood with the Milgram Experiment and the Stanford Prison Experiment. The cops are a group exercising power over another group, and they are following orders (not talking about Chauvin and his abetters here; they’re criminals). It’s an ugly part of human psychology I guess. Can this be curtailed, and if so, how?
