Observation and Recall Flashcards

An officer on patrol notices a parked van on a street where burglaries have been occurring. The van has no front license plate, tinted windows, and the engine appears to have been running recently (heat shimmer visible). Which observation is MOST legally significant?

Answer: The missing front license plate

A missing front license plate is a specific, articulable violation that provides legal justification for a contact, unlike the other contextual observations.

During a traffic stop, an officer notices the driver's hands are shaking, there is a strong odor of alcohol, and the passenger is avoiding eye contact. For the report, these observations should be documented as:

Answer: Objective observations noted by the officer

Reports must document observable facts as objective observations; conclusions like 'intoxicated' are for charging documents and court testimony.

You respond to a reported disturbance and observe a crowd of approximately 15 people. Later you are asked how many people were present. Your best answer should be:

Answer: Approximately 15, based on your on-scene estimate

An honest estimate with appropriate qualifier ('approximately') is both accurate and credible testimony.

At a robbery scene, you observe a shattered display case, cash register open and empty, and a single muddy boot print near the exit. In what order should you prioritize documenting these observations?

Answer: Perishable evidence first (boot print), then more permanent evidence

Perishable or fragile evidence like footprints must be documented and protected first because it can be destroyed by weather, foot traffic, or time.

While canvassing after a shooting, a witness tells you she 'heard two or three shots' from 'maybe half a block away.' How should you record this in your report?

Answer: Witness reported hearing 2-3 gunshots from approximately half a block away

Accurate reporting preserves the witness's own hedged language, capturing both the approximate count and approximate distance.

An officer is shown a suspect lineup six hours after witnessing an assault. Research on eyewitness memory suggests the officer's identification will be MOST reliable if:

Answer: The lineup is conducted by an officer who does not know which position the suspect is in

A double-blind lineup administered by someone unaware of the suspect's position eliminates administrator influence and produces more reliable identifications.

During a vehicle pursuit, an officer observes the fleeing car strike a parked vehicle, turn left on Oak Street, and then turn right into an alley. When radioing this information, the officer should convey:

Answer: The collision, then the left turn onto Oak, then the right into the alley — in chronological order

Providing a chronological sequence of locations gives dispatch and responding units a movement trail to intercept or anticipate the vehicle's direction.
