NTN Police Observation and Recall 4 — Questions and Answers
Question 1: An officer witnesses a vehicle collision at an intersection. The striking vehicle was a blue sedan with partial plate 'KLM'. The driver, a heavyset male in his 40s wearing a red jacket, fled on foot heading northwest. Which detail is MOST critical to broadcast first?
- The direction the driver fled
- The driver's clothing color
- The partial plate number (Correct answer)
- The vehicle color and make
Correct answer: The partial plate number
A partial plate number is the most actionable identifying detail for locating a specific vehicle quickly.
Question 2: During a foot patrol, you observe a suspicious male loitering near a jewelry store. You note he is approximately 5'10", wearing a gray hoodie, blue jeans, and white sneakers, and has a tattoo on his left forearm. Twenty minutes later, a robbery is reported. What information should you radio in FIRST?
- The tattoo description
- The full physical description and last known direction (Correct answer)
- Only the clothing description since it's most visible
- The time you first observed him
Correct answer: The full physical description and last known direction
A complete physical description combined with last known direction gives responding officers the best chance of locating the suspect.
Question 3: You are asked to recall a scene you observed 30 minutes ago. Which memory strategy is MOST effective for accurately recalling specific details of a crime scene?
- Reconstruct the scene mentally from the center outward in a systematic pattern
- Focus only on the most unusual or alarming elements
- Write down everything immediately after leaving the scene (Correct answer)
- Discuss the scene with a partner to fill in gaps
Correct answer: Write down everything immediately after leaving the scene
Writing notes immediately after observation preserves accurate detail before memory fades or becomes contaminated by later input.
Question 4: A witness describes a getaway car as 'dark colored, maybe black or dark blue, four-door, with a loud exhaust.' An officer should record this description as:
- A black four-door sedan with modified exhaust
- A dark-colored four-door vehicle, possibly black or dark blue, with a loud exhaust (Correct answer)
- A dark blue sedan — black is less common at night
- Unknown color four-door vehicle
Correct answer: A dark-colored four-door vehicle, possibly black or dark blue, with a loud exhaust
Officers must record witness descriptions exactly as given, including uncertainty, rather than making assumptions.
Question 5: While on patrol, you drive past a house and notice the front door is ajar, a lamp is knocked over inside, and an elderly woman is standing on the porch looking distressed. Which observation is the STRONGEST indicator of a possible crime?
- The lamp being knocked over
- The combination of the open door, overturned lamp, and distressed resident (Correct answer)
- The elderly woman standing on the porch
- The front door being ajar alone
Correct answer: The combination of the open door, overturned lamp, and distressed resident
Multiple simultaneous indicators together — not any single one — constitute the strongest signal of a potential crime.
Question 6: An officer studying a crime scene photograph later testifies about what she observed. Defense counsel challenges her recollection because the photo shows a detail she did not mention. What is the BEST explanation for this gap?
- The officer fabricated her account
- Selective attention causes observers to encode only salient or relevant details, missing background elements (Correct answer)
- Crime scene photos always capture more than the human eye
- The officer was not properly trained
Correct answer: Selective attention causes observers to encode only salient or relevant details, missing background elements
Selective attention is a well-documented phenomenon where observers naturally focus on salient elements and miss peripheral details.
Question 7: You observe two males arguing outside a bar. Male #1 is tall, blond, wearing a green shirt; Male #2 is shorter, dark hair, wearing a black jacket. Male #2 suddenly shoves Male #1 and runs east. To describe Male #2 accurately, you should note:
- Only his jacket color since it's most distinctive
- Height relative to Male #1, hair color, jacket color, and direction of flight (Correct answer)
- Only the direction he ran since location is perishable
- Hair and jacket color only
Correct answer: Height relative to Male #1, hair color, jacket color, and direction of flight
A complete description includes physical characteristics, clothing, and direction of travel so other officers can identify and locate the subject.
