Recent years have seen an explosion of protest against police brutality and repression—most dramatically in Ferguson, Missouri, where longheld grievances erupted in violent demonstrations following the police killing of Michael Brown.

Unfortunately, these reforms will not produce results, either alone or in combination. The core of the problem must be addressed: the nature of modern policing itself. “Broken windows” practices, the militarization of law enforcement, and the dramatic expansion of the police’s role over the last forty years have created a mandate for officers that must be rolled back.
