Q1: Which constitutional amendment protects individuals against unreasonable
searches and seizures and generally requires probable cause for the issuance of
a warrant?
A. Fifth Amendment
B. Sixth Amendment
C. Fourth Amendment [CORRECT]
D. Fourteenth Amendment
Correct Answer: C
Rationale: The Fourth Amendment specifically guards against unreasonable
searches and seizures and sets the probable-cause standard for warrants. The
Fifth addresses self-incrimination, the Sixth covers counsel and trial rights, and
the Fourteenth concerns equal protection and due process applied to the states.
Q2: Under Miranda v. Arizona, warnings are required when which two conditions
are present?
A. Detention and questioning about non-criminal matters
B. Probable cause and a formal arrest
C. Custody and interrogation [CORRECT]
D. Reasonable suspicion and a Terry stop
Correct Answer: C
Rationale: Miranda applies only when a person is both in custody and subject to
interrogation. Mere detention or reasonable suspicion does not trigger the
requirement; formal arrest alone is insufficient without interrogation.
Q3: An officer stops a pedestrian based on reasonable suspicion that the person
is about to commit a crime and conducts a limited pat-down for weapons. This
action is authorized by which case?
A. Miranda v. Arizona
,B. Terry v. Ohio [CORRECT]
C. Mapp v. Ohio
D. Gideon v. Wainwright
Correct Answer: B
Rationale: Terry v. Ohio established the authority for an investigative stop based
on reasonable suspicion and a limited frisk for weapons when the officer
reasonably believes the person may be armed. Miranda concerns custodial
interrogation; Mapp involves the exclusionary rule; Gideon addresses right to
counsel.
Q4: The exclusionary rule generally bars the use of evidence obtained in violation
of which amendment?
A. First Amendment
B. Second Amendment
C. Fourth Amendment [CORRECT]
D. Eighth Amendment
Correct Answer: C
Rationale: The exclusionary rule primarily suppresses evidence obtained through
unconstitutional searches and seizures under the Fourth Amendment. It is a
judicially created remedy to deter police misconduct.
Q5: Actions taken by an officer “under color of law” refer to:
A. Only those actions that strictly comply with written departmental policy
B. Actions taken while using the authority of government office, even if the officer
exceeds lawful authority [CORRECT]
C. Only off-duty conduct that involves a badge
D. Actions taken solely in a personal capacity
Correct Answer: B
Rationale: Color of law covers any misuse of official power. An officer acting
outside the scope of lawful authority may still be acting under color of law for
purposes of civil-rights liability.
Q6: Qualified immunity protects a law-enforcement officer from civil liability
unless the officer:
,A. Violates a clearly established constitutional right of which a reasonable officer
would have known [CORRECT]
B. Makes any mistake of fact
C. Uses force that results in injury
D. Arrests a person who is later found not guilty
Correct Answer: A
Rationale: Qualified immunity shields officers unless they violate a clearly
established right that a reasonable officer in the same situation would have
known was violated. Mere mistakes of fact or unsuccessful prosecutions do not
automatically defeat immunity.
Q7: The Fifth Amendment privilege against self-incrimination is the foundation for
which requirement?
A. Probable-cause warrants
B. Miranda warnings prior to custodial interrogation [CORRECT]
C. Speedy trial rights
D. Equal protection in enforcement
Correct Answer: B
Rationale: Miranda warnings are designed to protect the Fifth Amendment right
against compelled self-incrimination during custodial interrogation.
Q8: The Sixth Amendment guarantees which of the following rights?
A. Freedom from unreasonable searches
B. Protection against self-incrimination
C. Assistance of counsel and a speedy public trial [CORRECT]
D. Equal protection of the laws
Correct Answer: C
Rationale: The Sixth Amendment secures the right to counsel, a speedy and
public trial, an impartial jury, and confrontation of witnesses. Search-and-seizure
protections are Fourth Amendment; self-incrimination is Fifth; equal protection is
Fourteenth.
Q9: The Equal Protection Clause of the Fourteenth Amendment prohibits:
, A. All differential treatment by police
B. Discriminatory enforcement of the law based on race, ethnicity, or other
protected characteristics [CORRECT]
C. The use of reasonable suspicion
D. Investigative stops of any kind
Correct Answer: B
Rationale: The Fourteenth Amendment requires that similarly situated persons be
treated alike and bars selective enforcement based on protected characteristics.
Q10: An officer develops reasonable suspicion that a person is armed and
presently dangerous. The officer may:
A. Conduct a full search incident to arrest
B. Perform a limited protective frisk for weapons [CORRECT]
C. Immediately place the person under arrest
D. Search the person’s vehicle without additional justification
Correct Answer: B
Rationale: Under Terry, a reasonable belief that the person is armed and
dangerous authorizes a limited pat-down for weapons, not a full search or
automatic arrest.
Q11: Probable cause is required for:
A. A Terry stop
B. An arrest or search warrant [CORRECT]
C. A consensual encounter
D. Asking for identification during a voluntary conversation
Correct Answer: B
Rationale: Probable cause is the constitutional standard for arrests and for the
issuance of search or arrest warrants. Reasonable suspicion is sufficient for a
Terry stop; consensual encounters require no suspicion.
Q12: During a custodial interrogation, an officer fails to give Miranda warnings.
Any resulting confession is generally:
A. Admissible if the suspect later waives rights
