Question 1History of Law Enforcement

Which English king is credited with establishing the office of the justice of the peace in the 14th century?

  1. Richard I
  2. Henry II
  3. Edward III Correct answer.
  4. William the Conqueror

Explanation

Edward III's commission of the peace in 1361 is conventionally credited with creating the justice of the peace as a lasting local office. The JP combined judicial and administrative authority in the counties and became a foundation of English local governance that American colonial law enforcement later borrowed from.

Question 2History of Law Enforcement

The frankpledge system brought to England by the Normans required local men to do what?

  1. Group into tithings responsible for one another's conduct Correct answer.
  2. Pay a yearly fee to the king for policing
  3. Serve as mounted knights for the sheriff
  4. Elect a constable to serve for life

Explanation

Frankpledge organized free men into tithings of roughly ten households who were mutually responsible for producing any member accused of a crime. It was a collective surety system rather than a paid or elected professional police force.

Question 3History of Law Enforcement

In colonial America, the 'watch' system that patrolled towns at night was most directly derived from which English practice?

  1. The hue and cry and parish watch Correct answer.
  2. The posse comitatus
  3. The court leet
  4. The Star Chamber

Explanation

The colonial night watch descended from English parish watch arrangements, in which householders took turns patrolling and raising the hue and cry after offenders. Colonial towns adapted this duty, often requiring adult male residents to serve watch rotations.

Question 4History of Law Enforcement

Which statement best describes the first organized, publicly funded municipal police force in the United States?

  1. It was formed in Philadelphia in 1751
  2. It was established in New York City in 1845 Correct answer.
  3. It was organized in Chicago in 1855
  4. It was created in Boston in 1838 under a state charter

Explanation

New York City's 1845 consolidation of its day and night watches into a unified municipal police department is widely treated as the first full-time, publicly funded city police force in the United States. Boston followed in 1854 and Philadelphia in 1855, so the earlier dates in the other options do not fit.

Question 5History of Law Enforcement

Sir Robert Peel's Metropolitan Police, established in London in 1829, was distinctive mainly because it was what?

  1. A privately funded merchant patrol
  2. A part-time militia of householders
  3. A military garrison assigned to policing
  4. A full-time, uniformed force under central government authority Correct answer.

The political spoils system affected early American policing in the nineteenth century primarily by doing what?

  1. Guaranteeing officers lifetime tenure
  2. Placing departments under federal control
  3. Requiring civil service examinations
  4. Tying police jobs and promotions to political patronage Correct answer.

Explanation

Under the spoils system, police appointments and promotions often depended on loyalty to a political party or ward boss rather than merit. This patronage weakened discipline and professionalism until civil service reform spread in the late nineteenth and early twentieth centuries.

  2. That crime rates fell sharply wherever patrol was doubled
  3. That patrol officers should be replaced by civilian monitors
  4. That foot patrol had little measurable effect on crime rates but improved residents' perceptions of safety Correct answer.

Explanation

The Newark study found that while foot patrol did not clearly reduce crime, residents felt safer and rated police more favorably. Such findings helped shift attention toward community relations and perceptions of safety.

Question 50History of Law Enforcement

The concept of 'problem-oriented policing' developed by Herman Goldstein emphasized what?

  1. Identifying and addressing the underlying conditions that generate recurring incidents Correct answer.
  2. Increasing arrest quotas for patrol officers
  3. Centralizing all investigations at the state level
  4. Responding to calls faster than competing agencies
