Figure 4.1 The Basic Purposes of
Policing in Democratic Societies
Copyright © 2020, 2018, 2016 Pearson Education, Inc. All Rights Reserved
Enforcing the Law
• Police operate under an official public mandate requiring
them to enforce the law
• This is not their only job
• The majority of police officer time is spent answering
nonemergency public service calls
• Only about 10% to 20% of all calls involve situations that
actually require a law enforcement response
• Police cannot enforce all the laws
• Police are also expected to support the law
Copyright © 2020, 2018, 2016 Pearson Education, Inc. All Rights Reserved
Apprehending Offenders
• Some offenders are apprehended during the investigation
of a crime or during/immediately after its commission
• Many offenders are only caught as the result of extensive
police work involving investigation
• Criminal investigation
– The process of discovering, collecting, preparing,
identifying, and presenting evidence to determine what
happened and who is responsible when a crime occurs
Copyright © 2020, 2018, 2016 Pearson Education, Inc. All Rights Reserved
Preventing Crime (1 of 2)
• Crime prevention
– A proactive approach to the problem of crime
– Anticipating, recognizing, and appraising a crime risk
and the initiation of action to eliminate or reduce it
• Techniques: access control, theft-deterrence devices, hot-
spot policing, predictive policing, etc.
• Programs: organized efforts that focus resources on
reducing a specific form of criminal threat
Copyright © 2020, 2018, 2016 Pearson Education, Inc. All Rights Reserved
Preventing Crime (2 of 2)
• Police ability to prevent crimes relies in part on their ability
to predict when/where crimes will occur
• Effective prediction allows limited resources to be assigned
to the areas with the greatest need (“hot spots”)
• CompStat:
– A process of crime analysis and police management
developed by the NYPD in the mid-1990s
– A form of predictive policing
Copyright © 2020, 2018, 2016 Pearson Education, Inc. All Rights Reserved
Preserving the Peace
• Virtually limitless police activity that does not only involve
activities that violate the law
• Focus on quality-of-life offenses as crime-reduction and
peacekeeping strategy
– Minor law violations that demoralize community
residents and businesspeople
– Acts that create physical disorder or reflect social
decay
• Broken windows theory of policing
Copyright © 2020, 2018, 2016 Pearson Education, Inc. All Rights Reserved
Providing Services
• Anyone can mobilize the police simply by calling them
• 911 calls are prioritized and then relayed to patrol officers,
specialized field units, or other emergency personnel
• Some states have adopted nonemergency call numbers
(311) in addition to 911

American Policing Today
• The organization of American policing is the most complex
in the world
• Three major legislative and judicial jurisdictions
– Federal
– State
– Local
• Each has a variety of police agencies to enforce its laws
• Little uniformity among jurisdictions regarding naming,
function, or authority of enforcement agencies
Copyright © 2020, 2018, 2016 Pearson Education, Inc. All Rights Reserved
Federal Agencies
• Federal law enforcement agencies are distributed among
14 U.S. government departments and 28 nondepartmental
entities

State Agencies (1 of 2)
• Most were created in late nineteenth and early twentieth
century to meet specific needs
• Wide diversity of state policing agencies exist
• Two main models of state policing—centralized and
decentralized

Local Agencies (1 of 2)
• Includes city and county agencies
– Municipal departments, rural sheriff’s departments,
specialized groups (campus police, transit police, etc.)
• Every incorporated municipality has the authority to create
its own police force
• Approximately 12,000 municipal departments and over
3,000 sheriff’s departments
• About half employ fewer than ten full-time officers
Copyright © 2020, 2018, 2016 Pearson Education, Inc. All Rights Reserved
Local Agencies (2 of 2)

Copyright © 2020, 2018, 2016 Pearson Education, Inc. All Rights Reserved
Private Protective Services
• Independent or proprietary commercial organizations that
provide protective services to employers on a contractual
basis
• Major reasons for recent growth in private security
– Increase in workplace crime
– Increased fear of crime/terrorism
– State fiscal crises
– Increased public awareness/use of private security
• May be in part responsible for recent drop in crime rates

Copyright © 2020, 2018, 2016 Pearson Education, Inc. All Rights Reserved
Community Policing and
Antiterrorism
• Community policing is a natural conduit for information
gathering and the development of counterterrorism
intelligence

funneled to federal agencies that have been charged with
developing national security intelligence
Copyright © 2020, 2018, 2016 Pearson Education, Inc. All Rights Reserved
Critique of Community Policing
• Community policing has become the major theme of police
reform
• Community policing plagued with problems
– Difficult to determine program effectiveness or citizen
satisfaction with the program
– Ambiguity surrounding the concept of community
– Not all police officers or managers are willing to accept
nontraditional images of police work.
– Efforts to promote community policing can demoralize
the department

Evidence-Based Policing (1 of 2)
• Law Enforcement Assistance Administration (LEAA)
– A now-defunct federal agency established under Title I
of the 1968 Omnibus Crime Control and Safe Streets
Act to funnel federal funding to state and local
agencies
– LEAA funding led to research-rich years from1969 to
1982

practices
• Focused on the practice of preventive patrol
• Study divided patrol beats into proactive, reactive, and
control zones
• Study found no significant differences in crime rate or
citizen fear of crime
• Second Kansas City study focused on response time
– Little effect on citizen satisfaction or arrest of suspects
Copyright © 2020, 2018, 2016 Pearson Education, Inc. All Rights Reserved
The Kansas City Experiment (2 of 2)
• Although the study called into question some basic
assumptions about patrol, it remains the backbone of
police work
• Directed patrol
– New police-management strategy designed to increase
the productivity of patrol officers through the scientific
analysis and evaluation of patrol techniques
– Put the most officers on the street where and when
crime is most prevalent

Evidence-Based Policing Today
• Involves the use of the best available research on the
outcomes of police work to implement guidelines and
evaluate agencies, units, and officers.
• EBP uses research to evaluate current practices
• EBP model called the single “most powerful force for
change” in policing today
• Successful law enforcement executives must be
consumers and appliers of research
– Do not have to be researchers but must use research
in their everyday work
Copyright © 2020, 2018, 2016 Pearson Education, Inc. All Rights Reserved
Discretion and the Individual Officer
• Police discretion
– The exercise of choice by law enforcement officers in
their daily activities
• Patrolling officers often decide against a strict enforcement
of the law, preferring instead to handle situations informally
• Widest exercise of discretion more likely in routine
situations involving relatively less serious violations of the
law
