As we approach the 21st century, there is a discernable shift in policing, from an incident-driven perspective to a proactive problem solving stance often described as "community policing."

The book describes existing and emerging means of providing psychological support to the law enforcement community in response to police needs to accommodate new technology, community-oriented problem solving technology, crime prevention, and sensitivity to community social changes. Senior psychologists who are sworn officers, federal agents and civilian employees of federal, state and local law enforcement agencies comprise the team of chapter authors. Their perspectives encompass their collective experience "in the trenches" and in law enforcement management and administrative support roles. They discuss traditional applications of psychology to police selection, training and promotion processes, and in trauma stress management and evaluation of fitness for duty. Concerns related to police diversity and police family issues are also addressed, as are unique aspects of police stress management.
