The Limited Authority of
American Law Enforcement
The United States has almost 18,000 public
law enforcement agencies. The jurisdiction
of each agency is carefully limited by law.
Law enforcement is also limited by the
procedural law derived from U.S. Supreme
Court decisions.
Chapter 5
The Limited Authority of
American Law Enforcement
Even compared with other democratic nations
of the world, the U.S. has remarkably more
police agencies that operate under far more
restrictions to their authority.
Like much of the criminal justice system, this
limited law enforcement model came from
Chapter 5
English Roots
Our familiar law enforcement system, in
which uniformed officers respond to calls for
help and plainclothes detectives investigate,
developed over hundreds of years in England.

The Tithing System
By the 12th century in England, the practice of
resolving disputes privately gave way to a
system of group protection, called the tithing
Chapter 5
tithing system
A private self-held protection system in early
medieval England, in which a group of ten families,
or a tithing, agreed to follow the law, keep the peace
in their areas, and bring law violators to justice.
Chapter 5
The Tithing System
In larger areas, ten tithings were grouped
together to form a hundred, and one or several
hundreds constituted a shire. The shire was
under the direction of the shire reeve.
Chapter 5
The Constable-Watch System
The Statute of Winchester, in 1285,
formalized the constable-watch system of
• One man from each parish was selected to be
• Citizens were drafted as (unpaid) watchmen, and
were required to come to the aid of a constable or
watchman who called for help.

citizens, under the direction of a constable, or chief
peacekeeper, were required to guard the city and to
pursue criminals.
The peacekeeper in charge of protection in early
English towns.

The London Metropolitan Police
• The Industrial Revolution brought a huge
influx of people into London, and along
with them, increasing poverty, public
disorder, and crime.
• In 1829, Parliament created the London
Metropolitan Police, a 1,000-member
professional force.
Chapter 5
The London Metropolitan Police
The police became known as bobbies or
peelers after Robert Peel, who had pushed for
their creation.
Chapter 5
The London Metropolitan Police
The police were organized around Peel’s
Principles of Policing.
• The London Police were organized according to
military rank and structure.
• The main function of the police was to prevent
crime by preventive patrol of the community.

The Development of American
Law Enforcement
The United States has more police
departments than any other nation in the
Virtually every community has its own police
force, creating a great disparity in the quality
of American police personnel and service.

became common (although
not necessarily effective) in
America developed with two separate law
enforcement systems.
Chapter 5
Municipal Police Forces
• In 1844, New York City created the first paid,
unified police force in the U.S.
• Other cities followed suit, creating their own police
departments, often merely an organization of the
existing day and night watch.
• It was not until after the Civil War that police
forces routinely began to wear uniforms and carry
Chapter 5
Tangle of Politics and Policing
• Until the 1920s in most American cities,
local political leaders maintained complete
control over the police force.
• The political and police systems in many
cities were corrupt, and jobs, politics, and
law enforcement all depended on paying
money to the right person.
Chapter 5
Southern Slave Patrols
• In the South, the earliest form of policing
was the plantation slave patrols.
• Slave codes prohibited slaves from:
– holding meetings
– leaving the plantation without permission
– traveling without a pass

Self-protection remains very popular in the
South and West.
Chapter 5
State Police Agencies
Growing populations, as well as the inability
of some local sheriffs and constables to
control crime, led states to create their own
law enforcement agencies.
• Texas officially created the Rangers in 1835.
• Pennsylvania established the first modern state law
enforcement agency in 1905.
• By the 1930s, every state had some form of state
law enforcement agency.
Chapter 5
Professionalism and Reform
• Until the late 19th century, there were no
qualifications required for law enforcement
• Cincinnati was the first city to require
qualifications of police officers:
– High moral character
– Foot speed
Chapter 5
Professionalism and Reform
It was not until the early 20th Century that
reformers began advocating training and
education for police officers.
Reformers also aimed to remove the police
from political influences.

The Structure of American Law
American law enforcement agencies are
extremely diverse in:
• Jurisdictions
• Responsibilities
• Employers (hospitals, colleges, transit
authorities may have their own police)

other services particular to the needs of that
state government.

Private security employment is often
categorized two ways:
Contract security

college football game
Example: the security
force for a corporation’s
manufacturing plants

peace officers.
Chapter 5
proprietary security
In-house protective services that a security staff,
which is not classified as sworn peace officers,
provide for the entity that employs them.

phenomenal growth of private security since
the 1970s:
• Declining revenues for public policing.
• The private nature of crimes in the workplace.
Companies can control and hide crimes by
