Police department design, political pressure, and racial inequality in arrests

open access: yesAmerican Journal of Political Science, EarlyView.
Abstract This paper theorizes a source of bias in discretionary arrests: strategic limits on police officer learning. Officers have a variety of tactics at their disposal besides arrest that they use for less serious offenses when they judge the underlying behavior to be less severe. In departments led by a chief with special expertise in crime control,
