JIBC - Justice Institute of British Columbia Investigation and Evidence Collection Questions and Answers — Questions and Answers
Question 1: An investigator arrives at a residential break-and-enter scene. The first responding officer has secured the perimeter but allowed the homeowner to walk through the house to identify missing items before the investigator's arrival. Which critical principle of evidence collection has been compromised?
- The Best Evidence Rule
- The principle of scene continuity (Correct answer)
- The public interest exception
- The hearsay evidence rule
Correct answer: The principle of scene continuity
The principle of scene continuity, a core aspect of crime scene management, has been compromised. Allowing the homeowner to walk through the scene before it was processed contaminates the area, potentially destroying, altering, or adding evidence (e.g., footprints, fingerprints). This action breaks the chain of control over the scene and complicates the ability to distinguish between evidence left by the suspect and contamination from others.
Question 2: During a custodial interview regarding a theft, an investigator decides to use the PEACE model. What is the primary goal of the 'Account' phase of this interviewing technique?
- To challenge the suspect with existing evidence of their guilt.
- To obtain a confession by establishing a rapport with the suspect.
- To allow the suspect to provide their uninterrupted version of events. (Correct answer)
- To explain the legal consequences of the alleged offence to the suspect.
Correct answer: To allow the suspect to provide their uninterrupted version of events.
The 'Account' phase of the PEACE model is designed to allow the interviewee to provide their full, uninterrupted account of the events in question. The primary goal is information gathering, not securing a confession. The interviewer uses open-ended questions and active listening to encourage the person to talk, and will only clarify or challenge inconsistencies in a later phase.
Question 3: An officer seizes a laptop from a suspect's apartment under the authority of a search warrant. To maintain the integrity of this digital evidence for court, which of the following is the MOST crucial concept to adhere to?
- Hearsay Rule
- Best Evidence Rule
- Character Evidence Rule
- Continuity of Evidence (Correct answer)
Correct answer: Continuity of Evidence
Continuity of Evidence, also known as the chain of custody, is paramount. It is the documented record of everyone who has handled the evidence from the moment of seizure until its presentation in court. An unbroken chain of custody ensures the court that the laptop has not been tampered with, altered, or substituted, thereby preserving its integrity as evidence. While the Best Evidence Rule is relevant to documentary evidence, continuity is the overarching principle for all physical and digital exhibits.
Question 4: Which of the following scenarios best illustrates a violation of an individual's rights under Section 8 of the Canadian Charter of Rights and Freedoms?
- An officer conducts a pat-down search of a person they have lawfully arrested.
- A border services officer inspects the trunk of a car at a designated port of entry.
- An investigator enters a suspect's home without a warrant based on a vague, uncorroborated tip. (Correct answer)
- A police officer asks a driver to provide a breath sample into an approved screening device during a traffic stop.
Correct answer: An investigator enters a suspect's home without a warrant based on a vague, uncorroborated tip.
Section 8 of the Charter protects against unreasonable search and seizure. Entering a person's home, where the expectation of privacy is highest, without a warrant and based only on a vague, uncorroborated tip is a clear violation of this right. The other options describe situations where searches are generally considered reasonable and lawful: search incident to arrest, searches at the border with a lower expectation of privacy, and demands for breath samples under specific legislation.
Question 5: An investigator needs to present a digitally recorded conversation in court. The original recording is on a micro-SD card, but they have created a high-quality copy on a USB drive for presentation. According to the 'Best Evidence Rule' in Canada, what is the general requirement?
- Only a certified transcript of the conversation is admissible.
- The copy on the USB drive is automatically preferred for its ease of use.
- The original micro-SD card must be produced unless its absence can be properly explained. (Correct answer)
- Testimony about the conversation's content is sufficient without the recording.
Correct answer: The original micro-SD card must be produced unless its absence can be properly explained.
The Best Evidence Rule generally requires that the original document or recording be presented in court to prove its contents. A copy may be accepted if the original is proven to be lost, destroyed, or otherwise legitimately unavailable. Therefore, the primary requirement is to produce the original micro-SD card unless there is a valid reason for its absence.
Question 6: When taking initial statements from several witnesses at a chaotic incident scene, what is an investigator's primary duty regarding the information they provide?
- To determine which witness is the most credible before taking any notes.
- To accurately record the details provided by each witness separately. (Correct answer)
- To have the witnesses collaborate to create a single, unified statement.
- To only record information that directly supports the initial theory of the event.
Correct answer: To accurately record the details provided by each witness separately.
The investigator's primary duty is to accurately record the information provided by each witness. This includes documenting their identity and their verbatim account of events as much as possible. It is crucial to keep witnesses separate to prevent their accounts from influencing one another and to capture each individual's unique perspective and recollection. Assessing credibility and synthesizing information happens later in the investigative process.
