Many scholars and police officials contend that policing has changed since 9/11/01 with a greater emphasis on domestic counterterrorism and intelligence activities, often referred to as “high policing.” Some have characterized this as the new homeland security era and model of policing. The specific strategies or approaches that guide police tactics and investigations vary among nations based on their respective laws, police organization, and other factors, and the degree to which the homeland security model has actually been implemented varies with each individual agency. This article examines common or promising trends, approaches and related issues, including intelligence-led policing, adapting community-oriented policing and traditional “low policing” (i.e., patrol, criminal investigations and emergency response) to homeland security, advanced technology applications, and the militarization or privatization of policing. However, a common lament among scholars is the dearth of empirical research on many of these issues.
