Contemporary policing is in crisis, a situation that has led to persistent calls to reform it. Unfortunately, many proposed solutions focus on piecemeal changes that ignore a fundamental problem-policing relies on a largely reactive approach that does not in any systematic or comprehensive way focus on crime prevention. Most of what the police do, such as responding to 911 calls for service and employing directed patrols or hot spots policing, fails to address the causes of crime. Compounding this problem is the absence of any institution or agency charged with prioritizing the prevention of crime and ensuring that police efforts support this goal. It is designed to fail. The Reinvention of Policing diagnoses this problem, along with many others, in American policing and then turns to solutions.
