NTN Police Observation and Recall 2 — Questions and Answers
Question 1: A witness to a robbery describes the suspect as wearing a gray hoodie, black cargo pants, white sneakers, and a blue baseball cap. The witness also says the suspect had a tattoo on the left forearm. Which detail is most useful for identifying the suspect if they changed clothes?
- The gray hoodie
- The blue baseball cap
- The tattoo on the left forearm (Correct answer)
- The black cargo pants
Correct answer: The tattoo on the left forearm
A tattoo is a permanent physical characteristic that cannot be removed like clothing and provides a unique identifier.
While clothing descriptions help in the immediate search, clothing can be discarded or changed within minutes. Physical characteristics such as tattoos, scars, birthmarks, and other distinguishing marks are permanent identifiers that remain even after a suspect changes appearance. A forearm tattoo would be visible during a stop or booking and is a much stronger long-term identifier than any clothing item.
Question 2: Officers are trained to use HENRY or similar classification systems for fingerprints. What is the primary reason fingerprints are such a reliable identification method?
- They can be taken from any surface
- No two individuals have identical fingerprint patterns (Correct answer)
- They remain unchanged even in extreme heat
- They are easier to collect than DNA
Correct answer: No two individuals have identical fingerprint patterns
Fingerprints are reliable identifiers because no two people — including identical twins — have the same fingerprint patterns.
The reliability of fingerprint identification as a forensic standard rests on two established principles: fingerprint patterns are unique to each individual (no two people share the same prints, even identical twins), and fingerprint patterns remain stable throughout a person's lifetime. This combination of uniqueness and permanence makes fingerprints one of the most powerful identification tools available to law enforcement.
Question 3: During a briefing, officers are shown a mug shot of a wanted suspect. The suspect has short brown hair, a beard, and a prominent scar above the right eyebrow. Which of these features should officers prioritize when scanning a crowd?
- Hair color, since it is the most visible feature
- The beard, since it is distinctive
- The scar above the right eyebrow, since it is permanent and cannot be quickly altered (Correct answer)
- The combination of hair color and beard
Correct answer: The scar above the right eyebrow, since it is permanent and cannot be quickly altered
Scars are permanent physical features that cannot be altered quickly, making them the most reliable identifier when other features may change.
When looking for a suspect in a crowd or in the field, officers should prioritize permanent, unchangeable physical features: scars, tattoos, bone structure, height, and build. Hair can be cut, dyed, or covered; a beard can be shaved in minutes. A scar above the right eyebrow is a permanent feature that remains visible even if the suspect changes their hair or shaves. Training officers to prioritize permanent features improves positive identification rates.
Question 4: You drive past a convenience store and see a man run out followed by the clerk yelling 'Stop, he's got my money!' You continue past before stopping. What is the most critical information to recall?
- The store's business hours
- A detailed description of the man: clothing, direction of flight, height, build, and any distinguishing features (Correct answer)
- The make and model of nearby parked cars
- The name of the store
Correct answer: A detailed description of the man: clothing, direction of flight, height, build, and any distinguishing features
A detailed physical and directional description of the fleeing suspect is the most critical information for broadcasting and locating the individual.
In a dynamic situation where a suspect is fleeing, the most operationally critical information is the suspect's description: physical characteristics (height, build, skin tone), clothing (colors, specific garments), direction of flight, and any distinguishing features. This information should be immediately broadcast to dispatch and nearby units to initiate an area search. While the store name may be useful for administrative purposes, it does not help locate a fleeing suspect.
Question 5: A patrol officer notices that a parked car has been in the same location for three days with a parking violation notice on the windshield. The car's plates come back as reported stolen. What pieces of information were important for the officer to have remembered from prior patrols?
- The color of the parking notice
- The car's make, model, color, and location from previous observations (Correct answer)
- The names of neighbors living near where the car is parked
- The weather on the days the car was observed
Correct answer: The car's make, model, color, and location from previous observations
Remembering the vehicle's make, model, color, and location across multiple patrols is what allowed the officer to identify the anomaly and check the plates.
Effective patrol observation requires officers to build a mental map of their patrol area, including what belongs and what represents an anomaly. Remembering the make, model, color, and specific location of a parked vehicle across multiple patrols is what triggers recognition that the vehicle has been stationary too long. This observational continuity is what led to the plate check and stolen vehicle discovery. This is a core competency of patrol observation — noticing things that seem out of place.
Question 6: You are a first responder to a hit-and-run collision. A witness says the vehicle was 'big and dark.' What follow-up questions would elicit the most useful information?
- 'Are you sure it was dark?'
- 'What type of vehicle was it — car, truck, or SUV? What shade of dark — black, dark blue, dark green? Did you see any distinctive markings, damage, or logos?' (Correct answer)
- 'Do you know what direction it went?'
- 'Have you seen this vehicle before?'
Correct answer: 'What type of vehicle was it — car, truck, or SUV? What shade of dark — black, dark blue, dark green? Did you see any distinctive markings, damage, or logos?'
Specific follow-up questions about vehicle type, exact color, and distinguishing features help refine a vague description into a usable broadcast description.
Witness accounts are often initially vague. Skilled officers ask structured follow-up questions to extract specific, actionable information. Breaking down 'big and dark' requires clarifying: vehicle type (car vs. truck vs. SUV significantly narrows the search), specific color shade (black vs. dark navy vs. forest green), and any distinguishing features (damage, decals, roof racks). Each specific detail narrows the field of potential suspect vehicles. Yes/no questions ('Are you sure?') provide little additional information.
