Police Officer Observation and Memory 2 — Questions and Answers
Question 1: Officers are shown a wanted suspect photo for 30 seconds. The BEST strategy for memorizing the description is to:
- Focus on unique identifying features such as scars, tattoos, and distinctive facial features (Correct answer)
- Try to memorize every detail equally
- Only look at the suspect's clothing
- Write down details without looking at the photo
Correct answer: Focus on unique identifying features such as scars, tattoos, and distinctive facial features
Unique identifying features such as scars, tattoos, birthmarks, and unusual facial features are the most reliable for recognition because they are less likely to change than clothing or hairstyle.
Effective suspect description memorization prioritizes permanent or semi-permanent features: facial scars, tattoos, birthmarks, missing teeth, unusual eye color, and distinctive bone structure. These cannot be changed in a few minutes, unlike clothing, hair color, or accessories.
Question 2: An officer observes a blue sedan parked in front of a building. When writing the report, the officer should record the vehicle as:
- A blue sedan with a partial description of distinguishing features observed (Correct answer)
- Possibly blue, maybe a car
- A suspicious vehicle that seemed out of place
- A blue vehicle of unknown type
Correct answer: A blue sedan with a partial description of distinguishing features observed
Officers should record exactly what they observed: the color (blue), type (sedan), and any other objective details noted such as make, model, license plate, or damage. Qualifying language weakens the description.
Precise vehicle descriptions include: color, body type (sedan, SUV, pickup), make, model, license plate number and state, and any distinguishing damage or modifications. Adding partial plate numbers, damage descriptions, or decals makes the description significantly more actionable.
Question 3: The principle of witness unreliability in law enforcement refers to the fact that:
- Human memory is reconstructive and can be influenced by stress, lighting, time, and post-event information (Correct answer)
- Witnesses always lie to protect suspects
- All eyewitness testimony is inadmissible in court
- Witnesses with criminal records cannot testify
Correct answer: Human memory is reconstructive and can be influenced by stress, lighting, time, and post-event information
Memory research consistently shows that human recall is imperfect and can be distorted by high stress, poor lighting, short observation time, and information received after the event.
Decades of psychological research demonstrate that eyewitness memory is reconstructive, not like a recording. Factors that reduce accuracy include: stress and fear, poor lighting, brief observation time, and post-event contamination. Officers should be aware of these limitations when evaluating witness accounts.
Question 4: An officer is patrolling and passes a man on the corner. Thirty minutes later, a robbery is reported matching the man's description. The officer should attempt to recall:
- Clothing, height, weight, race, distinguishing features, and direction the man was heading (Correct answer)
- Only the man's race
- Only what the man was wearing
- Whether the man seemed suspicious or not
Correct answer: Clothing, height, weight, race, distinguishing features, and direction the man was heading
Comprehensive description recall including clothing, physical characteristics, and last known direction of travel gives investigators the best chance of locating the suspect.
When attempting to recall an individual seen before a crime, officers should mentally reconstruct: clothing (colors, style, any logos), physical attributes (height, build, race, approximate age), facial features, and directional movement. Even partial information such as a distinctive jacket color can be operationally valuable.
Question 5: During a foot pursuit, an officer radios: Suspect entered gray building, northwest corner of 5th and Oak. This communication demonstrates:
- Good situational awareness and precise location reporting (Correct answer)
- Unnecessary detail that slows the pursuit
- A violation of radio protocols
- A failure to maintain visual contact
Correct answer: Good situational awareness and precise location reporting
Providing specific, real-time location information (building color, corner of intersection) enables other units to respond accurately and effectively.
Effective radio communication during pursuits requires rapid, specific observations. Identifying the building by a distinguishing characteristic (gray), its position (northwest corner), and the intersection (5th and Oak) gives backup units unambiguous information. Observation and communication skills are directly linked.
Question 6: A witness to an assault says it happened so fast I did not get a good look. This statement indicates:
- The witness's observation time was short, which may reduce description accuracy (Correct answer)
- The witness is lying and trying to avoid involvement
- The assault did not occur
- The witness was not paying attention intentionally
Correct answer: The witness's observation time was short, which may reduce description accuracy
Short observation time is one of the strongest predictors of reduced eyewitness accuracy. Officers and courts must weigh this when evaluating the reliability of the description that follows.
Research on eyewitness testimony shows a direct correlation between observation duration and accuracy. When events happen fast, witnesses have less time to encode facial features, clothing details, and physical characteristics into memory. This is not evidence of dishonesty - it reflects a limitation of human perception.
