UDEE Critical Thinking 3 — Questions and Answers
Question 1: An officer is reviewing surveillance footage and notices a person entering a store at 3:05 PM but the receipt shows a purchase time of 2:58 PM. The most reasonable action is to:
- Assume the receipt is fraudulent
- Verify whether the store's camera clock and register clock are synchronized (Correct answer)
- Arrest the store clerk for falsifying records
- Discard the footage as unreliable
Correct answer: Verify whether the store's camera clock and register clock are synchronized
Time discrepancies between devices are often caused by unsynchronized clocks and must be verified before drawing conclusions.
Question 2: Which scenario best illustrates the concept of 'modus tollens' in logical reasoning?
- If it rains, the road is wet; it is raining; therefore the road is wet
- If the alarm triggered, someone entered; the alarm did not trigger; therefore no one entered (Correct answer)
- Most criminals flee the scene; this person fled; therefore this person is a criminal
- The suspect was seen nearby; nearby suspects are usually guilty
Correct answer: If the alarm triggered, someone entered; the alarm did not trigger; therefore no one entered
Modus tollens: if P then Q; not Q; therefore not P — here, no alarm means no entry was triggered.
Question 3: A supervisor tells an officer: 'Either the informant is lying, or the suspect was at the warehouse.' The officer confirms the informant told the truth. What follows?
- The suspect was definitely at the warehouse (Correct answer)
- The informant may still be lying about other matters
- No conclusion can be drawn without more evidence
- The supervisor's statement was illogical
Correct answer: The suspect was definitely at the warehouse
In a valid 'either/or' (disjunctive) argument, confirming one side as false forces the other side to be true.
Question 4: An officer must prioritize three simultaneous radio calls: a domestic disturbance, a traffic accident with injuries, and a noise complaint. The most critical thinking skill here is:
- Following alphabetical order of call types
- Responding to the most recently received call
- Evaluating urgency and potential for harm to prioritize the injury accident first (Correct answer)
- Assigning all calls equal priority to avoid bias
Correct answer: Evaluating urgency and potential for harm to prioritize the injury accident first
Critical thinkers assess severity and life-safety risk to allocate limited response resources effectively.
Question 5: Which statement represents an assumption rather than an established fact in an investigation?
- The victim's wallet was recovered 2 blocks from the scene
- The suspect must have known the victim's schedule to intercept her (Correct answer)
- Three witnesses identified the same vehicle
- The incident occurred at 11:47 PM according to camera timestamps
Correct answer: The suspect must have known the victim's schedule to intercept her
Stating the suspect 'must have known' the victim's schedule is an inference presented as fact without direct evidence.
Question 6: When evaluating information credibility, an officer should give LEAST weight to:
- Corroborated witness statements
- Physical evidence processed by a forensic lab
- An anonymous tip that cannot be verified or sourced (Correct answer)
- A suspect's statement recorded under caution
Correct answer: An anonymous tip that cannot be verified or sourced
Unverifiable anonymous tips lack source accountability and corroboration, making them the least credible form of information.
Question 7: An officer concludes a person is intoxicated based solely on the smell of alcohol. This conclusion is an example of:
- Definitive proof of intoxication
- A reasonable inference that requires additional field tests to confirm (Correct answer)
- Irrelevant observation that should be excluded from the report
- A deductive conclusion requiring no further testing
Correct answer: A reasonable inference that requires additional field tests to confirm
The odor of alcohol is an indicator but not proof of legal intoxication; standardized field sobriety tests are needed to confirm.
