Logical Reasoning in Policing Flashcards

An officer reads: 'No person shall park within 5 meters of a fire hydrant.' A vehicle is found 4.8 meters from a hydrant. Should a parking violation be issued?

Answer: Yes, because 4.8 meters is less than the required 5-meter minimum

4.8 meters is strictly less than the 5-meter minimum clearance required by law, so a violation exists regardless of how close the measurement is.

Crime data shows 60% of shoplifting incidents at Store A occur between 3–5 PM. A store manager asks when to increase security coverage. What is the most evidence-based recommendation?

Answer: 3–5 PM, since that is when the majority of incidents occur

Directing security resources to the 3–5 PM window targets 60% of incidents, providing the greatest return on security investment based on actual data.

Premise 1: Suspects who flee on foot are more likely to discard evidence. Premise 2: The suspect fled on foot. Conclusion: The suspect likely discarded evidence. Is this reasoning valid?

Answer: Yes, the conclusion follows logically from the premises

This is a valid deductive syllogism — the conclusion follows directly from the two premises without requiring additional assumptions.

Three witnesses give different descriptions of a getaway car: 'dark blue,' 'dark green,' and 'black.' Which investigative action is most logical?

Answer: Focus on dark-colored vehicles as the common thread across all descriptions

The common element across all three descriptions is a dark color, so focusing on dark-colored vehicles represents the most logical synthesis of available witness information.

An officer discovers that a bylaw violation report filed last Tuesday is missing from the system. Today is Monday. The filing deadline is 7 days from the incident. What is the most urgent action?

Answer: Immediately re-file the report and notify a supervisor of the discrepancy

With the 7-day deadline approaching and no record found, immediate re-filing and supervisor notification protects legal compliance and departmental accountability.

A logic grid: If it rains, the outdoor event is cancelled. The outdoor event was not cancelled. What can be concluded?

Answer: It did not rain

By contrapositive logic — if rain causes cancellation and the event was NOT cancelled, then it did NOT rain.

An officer must process four tasks: file an arrest report (due in 2 hours), respond to a non-emergency call (due in 4 hours), submit overtime forms (due in 6 hours), and attend a briefing (starting in 1 hour). In what order should the tasks be completed?

Answer: Briefing, arrest report, non-emergency call, overtime forms

The briefing starts first (1 hour), followed by the arrest report deadline (2 hours), then the non-emergency call (4 hours), and overtime forms last (6 hours).
