OACP - Ontario Association of Chief of Police Logical Reasoning and Analysis Questions and Answers — Questions and Answers
Question 1: A community reports a rise in vandalism during the same summer months that ice cream sales are highest. A resident concludes that eating ice cream causes people to commit vandalism. What is the primary flaw in this reasoning?
- The resident is using a circular argument.
- The resident is confusing correlation with causation. (Correct answer)
- The resident is appealing to emotion instead of logic.
- The resident is making a hasty generalization from a small sample size.
Correct answer: The resident is confusing correlation with causation.
The rise in both vandalism and ice cream sales is likely due to a third factor, such as warmer weather and more people being outside, not because one causes the other. This is a classic example of confusing correlation (two things happening at the same time) with causation (one thing causing the other).
Question 2: A police service has the following policy: 'Officers must activate their body-worn camera (BWC) *before* initiating any investigative or enforcement encounter. A traffic stop is defined as an enforcement encounter.' Officer Davis pulls over a vehicle for speeding but only activates her BWC after she has approached the driver's window and started speaking. Based *only* on these facts, which conclusion is certain?
- Officer Davis did not follow the BWC policy. (Correct answer)
- The driver of the vehicle was uncooperative.
- The BWC footage will be inadmissible in court.
- Officer Davis forgot to charge her BWC.
Correct answer: Officer Davis did not follow the BWC policy.
The policy states the BWC must be activated *before* the encounter begins. A traffic stop is an enforcement encounter. By activating the camera *after* approaching and speaking to the driver, Officer Davis did not adhere to the stated policy. The other options are assumptions or potential consequences, not certain conclusions from the given facts.
Question 3: An investigator at a burglary scene states, 'The suspect obviously knew the occupants were on vacation, which is why they chose to break in this week.' What is the primary, unstated assumption the investigator is making?
- The suspect lives in the same neighbourhood.
- The break-in was not a random act. (Correct answer)
- The suspect has committed similar crimes before.
- The occupants posted their vacation plans on social media.
Correct answer: The break-in was not a random act.
The investigator's statement assumes the timing of the crime was intentional and based on specific knowledge. This rests on the core assumption that the crime was targeted and not simply a random opportunity. The other options are possible explanations for *why* it might not be random, but they are not the fundamental assumption itself.
Question 4: An officer writes the following in their notebook: 'The driver had bloodshot eyes and slurred his speech. He was clearly intoxicated.' Which part of this statement is an inference rather than an observation?
- "The driver had bloodshot eyes"
- "and slurred his speech"
- "He was clearly intoxicated" (Correct answer)
- All parts of the statement are observations.
Correct answer: "He was clearly intoxicated"
"Bloodshot eyes" and "slurred speech" are direct sensory observations. "He was clearly intoxicated" is a conclusion or inference drawn from those observations. While the inference may be correct, other factors (fatigue, medical issues) could cause the observed signs. In official reporting, it's crucial to distinguish between what is seen/heard and the conclusions drawn from it.
Question 5: You are analyzing witness statements to reconstruct a timeline. Statement 1: 'The suspect ran out the front door just after I heard the alarm.' Statement 2: 'The glass shattered, and then the alarm started ringing.' Statement 3: 'I saw the suspect near the building moments before I heard glass shatter.' What is the correct chronological sequence of events?
- Alarm sounds -> Suspect runs out -> Glass shatters.
- Suspect seen near building -> Alarm sounds -> Glass shatters -> Suspect runs out.
- Glass shatters -> Suspect runs out -> Alarm sounds -> Suspect seen near building.
- Suspect seen near building -> Glass shatters -> Alarm sounds -> Suspect runs out. (Correct answer)
Correct answer: Suspect seen near building -> Glass shatters -> Alarm sounds -> Suspect runs out.
Statement 3 places the suspect at the scene first. Statement 2 establishes that the glass shattering happened *before* the alarm. Statement 1 shows the suspect fled *after* the alarm. Combining these logically creates the sequence: Suspect seen -> Glass shatters -> Alarm sounds -> Suspect runs out.
Question 6: A single, unidentified footprint is found in the mud beneath a window that was forced open at a crime scene. Which of the following is the MOST logical and defensible inference to be drawn from this fact alone?
- The crime was committed by only one person.
- The suspect wore a specific size and brand of shoe.
- A person was standing in that specific location at some point after it last rained. (Correct answer)
- The person who left the footprint is guilty of the crime.
Correct answer: A person was standing in that specific location at some point after it last rained.
The only certain conclusion is that someone was present at that spot. Inferring guilt (D) is a major leap. Determining the shoe brand (B) may be possible with analysis but isn't the primary inference about the event itself. Assuming only one perpetrator (A) is not supported by a single footprint. The most logical and limited inference is about presence at the location.
