Sample Questions

1. Which reformer is most closely associated with the creation of the Metropolitan Police in London in 1829?

  • A. August Vollmer
  • B. Sir Robert Peel
  • C. O. W. Wilson
  • D. J. Edgar Hoover
Show Answer for Question 1
Answer: B. Sir Robert Peel

Sir Robert Peel is closely associated with the Metropolitan Police Act of 1829 and the development of London’s Metropolitan Police.

His name is also the source of the traditional nickname bobbies for British police officers.

2. Which participant in the criminal-justice process is primarily responsible for deciding whether to file or pursue criminal charges on behalf of the government?

  • A. Prosecutor
  • B. Defense attorney
  • C. Probation officer
  • D. Court clerk
Show Answer for Question 2
Answer: A. Prosecutor

Prosecutors represent the government in criminal cases and exercise substantial discretion over charging decisions.

Defense attorneys represent the accused, while probation officers and court clerks perform different functions.

3. Which source is specifically designed to estimate both crimes reported to police and crimes that victims did not report to police?

  • A. National Crime Victimization Survey
  • B. National Incident-Based Reporting System
  • C. Police personnel roster
  • D. Court sentencing database
Show Answer for Question 3
Answer: A. National Crime Victimization Survey

The National Crime Victimization Survey asks people about criminal victimizations they experienced, including incidents never reported to police.

Law-enforcement reporting systems such as NIBRS are based on crimes known to participating law-enforcement agencies.

4. Which law-enforcement agency would most likely have primary responsibility for routine patrol and enforcement of local ordinances within a city?

  • A. Municipal police department
  • B. Federal Bureau of Investigation
  • C. United States Secret Service
  • D. Drug Enforcement Administration
Show Answer for Question 4
Answer: A. Municipal police department

Municipal police departments typically handle routine patrol, calls for service, local criminal-law enforcement, and city ordinances.

Federal agencies have specialized federal responsibilities rather than general responsibility for ordinary municipal patrol.

5. In a traditional police organization, what does the term chain of command describe?

  • A. The formal line of authority through supervisory levels
  • B. A list of criminal statutes arranged by penalty
  • C. The sequence used to process physical evidence
  • D. A rotating schedule for patrol assignments
Show Answer for Question 5
Answer: A. The formal line of authority through supervisory levels

The chain of command identifies how authority and responsibility flow through an organization.

It helps employees know who supervises them, who receives reports, and where decisions are made within the hierarchy.

6. Which approach most clearly reflects community policing?

  • A. Focusing only on arrests after crimes occur
  • B. Building ongoing partnerships with residents to identify and address local problems
  • C. Assigning all patrol decisions exclusively to federal agencies
  • D. Eliminating officer discretion in every situation
Show Answer for Question 6
Answer: B. Building ongoing partnerships with residents to identify and address local problems

Community policing emphasizes partnerships between law enforcement and the public, along with collaborative problem solving.

The approach seeks to address underlying community concerns rather than relying only on reactive enforcement.

7. Police discretion is best defined as an officer’s ability to:

  • A. Ignore constitutional limits when circumstances seem urgent
  • B. Choose among lawful alternatives when deciding how to handle a situation
  • C. Create new criminal statutes while on patrol
  • D. Overrule any decision made by a court
Show Answer for Question 7
Answer: B. Choose among lawful alternatives when deciding how to handle a situation

Police discretion refers to judgment exercised within legal and departmental limits.

Depending on the law and policy, an officer may sometimes choose among several lawful responses to a situation.

8. Which policing strategy begins by identifying a recurring problem, analyzing its causes, developing a tailored response, and assessing the results?

  • A. Problem-oriented policing
  • B. Random patrol
  • C. Strict military policing
  • D. Reactive case processing
Show Answer for Question 8
Answer: A. Problem-oriented policing

Problem-oriented policing focuses on recurring problems rather than treating each incident as isolated.

A commonly used framework is SARA: scanning, analysis, response, and assessment.

9. Under Terry v. Ohio, an officer may briefly stop a person when the officer has:

  • A. Proof beyond a reasonable doubt that a crime occurred
  • B. A warrant signed by a judge in every case
  • C. Reasonable suspicion based on specific and articulable facts
  • D. A completed criminal conviction
Show Answer for Question 9
Answer: C. Reasonable suspicion based on specific and articulable facts

Terry v. Ohio recognized that a brief investigatory stop may be reasonable under the Fourth Amendment when supported by reasonable suspicion.

A protective frisk for weapons requires an additional reasonable basis to believe the person is armed and dangerous.

10. Miranda warnings are generally required before police conduct which type of questioning?

  • A. Any conversation between an officer and a member of the public
  • B. Custodial interrogation
  • C. Every traffic stop regardless of questioning
  • D. Every request for identification
Show Answer for Question 10
Answer: B. Custodial interrogation

The core Miranda rule applies when a person is both in custody and subjected to interrogation.

The rule does not mean that every police conversation, routine question, or brief encounter automatically requires Miranda warnings.

How to Use These Questions

For organization and management questions, distinguish formal structure from policing strategies. Terms such as chain of command, community policing, problem-oriented policing, and discretion describe different aspects of how law-enforcement agencies operate.

For constitutional-law questions, identify the stage of the encounter first. A brief investigative stop, an arrest, a search, and custodial interrogation involve different legal standards.

These practice questions are not official DSST questions and are not endorsed by DSST or Prometric.
