Frontline National Test Law Enforcement 2 — Questions and Answers
Question 1: A suspect invokes their right to remain silent during a custodial interrogation. What must officers do?
- Continue questioning about unrelated offenses
- Immediately cease all interrogation (Correct answer)
- Allow a 30-minute break then resume questioning
- Obtain a supervisor's approval to continue
Correct answer: Immediately cease all interrogation
Once a suspect invokes the right to silence under Miranda, all interrogation must stop immediately.
Question 2: Which doctrine allows evidence obtained illegally to still be admitted if it would have inevitably been discovered through lawful means?
- Good faith exception
- Plain view doctrine
- Inevitable discovery doctrine (Correct answer)
- Independent source doctrine
Correct answer: Inevitable discovery doctrine
The inevitable discovery doctrine, established in Nix v. Williams, permits admission of evidence that would have been found through routine lawful investigation.
Question 3: An officer observes a traffic violation and stops the vehicle. During the stop, the officer smells marijuana. Under what authority can the officer search the car?
- Consent only — the driver must agree
- Probable cause — the odor alone is sufficient (Correct answer)
- The officer must obtain a warrant before searching
- Exigent circumstances only
Correct answer: Probable cause — the odor alone is sufficient
The odor of marijuana emanating from a vehicle establishes probable cause to search without a warrant under the automobile exception.
Question 4: Which type of lineup procedure is considered the most reliable for eyewitness identification?
- Simultaneous showup at the crime scene
- Sequential blind lineup (Correct answer)
- Simultaneous lineup administered by the case detective
- Photo array shown all at once
Correct answer: Sequential blind lineup
Sequential blind lineups, where a neutral administrator shows photos one at a time, reduce suggestiveness and relative judgment errors.
Question 5: What is the legal standard required for an officer to conduct a 'Terry stop'?
- Probable cause to arrest
- Reasonable articulable suspicion of criminal activity (Correct answer)
- Preponderance of evidence
- A written warrant signed by a magistrate
Correct answer: Reasonable articulable suspicion of criminal activity
Terry v. Ohio established that a brief investigatory stop requires only reasonable articulable suspicion, a lower standard than probable cause.
Question 6: An officer is called to a domestic dispute where the victim has visible injuries. The suspect denies assault. What should the officer's primary concern be?
- Collecting physical evidence for prosecution
- Ensuring the safety of all parties and the victim (Correct answer)
- Persuading the victim to press charges
- Conducting a full interrogation of the suspect on scene
Correct answer: Ensuring the safety of all parties and the victim
Officer safety and victim safety are always the primary priorities at a domestic disturbance call.
Question 7: What information is NOT typically required on an arrest warrant?
- The suspect's name or description
- The offense charged
- The arresting officer's personal address (Correct answer)
- A judge's signature
Correct answer: The arresting officer's personal address
An arrest warrant requires the suspect's identification, the charged offense, and judicial authorization — the officer's personal address is not required.
A suspect invokes their right to remain silent during a custodial interrogation.
