MPOETC Evidence & Trial Practice 4 — Questions and Answers
Question 1: Which standard of proof is required to obtain a search warrant?
- Beyond a reasonable doubt
- Clear and convincing evidence
- Probable cause (Correct answer)
- Preponderance of the evidence
Correct answer: Probable cause
The Fourth Amendment requires probable cause — a reasonable belief based on articulable facts — to obtain a search warrant.
Question 2: At trial, an officer's written report is typically considered which type of evidence when used to refresh the officer's recollection?
- Hearsay that is automatically inadmissible
- A business record admissible as substantive evidence
- A past recollection recorded, usable when present memory fails (Correct answer)
- Privileged communication exempt from disclosure
Correct answer: A past recollection recorded, usable when present memory fails
When a witness cannot recall a matter and a prior writing fails to refresh memory, it may be admitted as a recorded recollection exception to hearsay.
Question 3: Which of the following describes the 'plain view' doctrine?
- Officers may search any area visible from a public street
- Officers may seize evidence without a warrant if they are lawfully present and the incriminating nature of the item is immediately apparent (Correct answer)
- Any evidence placed in a public location is admissible regardless of how it was obtained
- Officers may enter a private dwelling if they can see evidence of a crime through a window
Correct answer: Officers may seize evidence without a warrant if they are lawfully present and the incriminating nature of the item is immediately apparent
The plain view doctrine allows warrantless seizure of evidence when the officer is lawfully present, the item is in plain view, and its incriminating nature is immediately apparent.
Question 4: Expert witnesses differ from lay witnesses in that expert witnesses are permitted to:
- Testify about events they personally witnessed at the crime scene
- Offer opinions beyond common knowledge based on specialized expertise (Correct answer)
- Introduce physical evidence directly without chain of custody documentation
- Testify without being subject to cross-examination
Correct answer: Offer opinions beyond common knowledge based on specialized expertise
Expert witnesses, qualified by knowledge, skill, or experience, may offer opinion testimony on matters beyond the understanding of average jurors.
Question 5: A defendant exercises the right to remain silent after receiving Miranda warnings. At trial, the prosecution may:
- Comment on the defendant's silence as evidence of guilt
- Not use pre-arrest silence against the defendant in most circumstances (Correct answer)
- Introduce the silence as substantive evidence of consciousness of guilt
- Require the defendant to explain the invocation of silence to the jury
Correct answer: Not use pre-arrest silence against the defendant in most circumstances
Post-Miranda silence generally cannot be used against a defendant at trial; doing so would penalize the exercise of a constitutional right.
Question 6: When an officer is asked a question on the stand that they do not know the answer to, the CORRECT response is to:
- Provide the most likely answer based on training and experience
- State 'I don't know' or 'I don't recall' if that is truthful (Correct answer)
- Ask the prosecutor to rephrase the question before answering
- Refer to another officer's testimony for the answer
Correct answer: State 'I don't know' or 'I don't recall' if that is truthful
Saying 'I don't know' or 'I don't recall' when that is true is required — guessing damages credibility and can constitute perjury.
Question 7: The 'best evidence rule' requires that:
- Only the most credible witness may testify about key facts
- The original document, recording, or photograph must be produced to prove its contents (Correct answer)
- Physical evidence must be in better condition than testimonial evidence
- Officers must obtain the best available warrant before conducting a search
Correct answer: The original document, recording, or photograph must be produced to prove its contents
The best evidence rule requires the original of a document, recording, or photograph to prove its contents, unless the original is unavailable.
