CFE Legal and Ethical Considerations in Forensics 2 — Questions and Answers
Question 1: A forensic examiner discovers evidence of a crime unrelated to the original case scope during an examination. What is the most appropriate course of action?
- Ignore it to stay within the original scope
- Immediately notify the client and document the discovery (Correct answer)
- Delete the unrelated evidence to avoid complications
- Proceed with the original examination only and say nothing
Correct answer: Immediately notify the client and document the discovery
Forensic examiners have an ethical and often legal duty to report discoveries of evidence of other crimes to the appropriate parties.
Question 2: Which legal doctrine holds that evidence obtained through illegal means, as well as any evidence derived from it, is inadmissible in court?
- Chain of custody doctrine
- Fruit of the poisonous tree doctrine (Correct answer)
- Best evidence rule
- Hearsay rule
Correct answer: Fruit of the poisonous tree doctrine
The 'fruit of the poisonous tree' doctrine excludes not only illegally obtained evidence but also any secondary evidence derived from it.
Question 3: When a forensic examiner is retained by the defense in a criminal case, to whom does the examiner owe their primary duty?
- The defendant personally
- The defense attorney
- The truth and the court (Correct answer)
- The public interest
Correct answer: The truth and the court
Regardless of who retains them, forensic examiners owe their primary duty to the truth and the court, not to the party that hired them.
Question 4: Under Federal Rule of Evidence 702, what must a forensic expert demonstrate before their testimony is admitted?
- Membership in a professional forensic association
- That their opinion is based on sufficient facts, reliable methods, and proper application of those methods (Correct answer)
- A minimum of ten years of field experience
- Certification by a federally recognized body
Correct answer: That their opinion is based on sufficient facts, reliable methods, and proper application of those methods
FRE 702 requires that expert testimony be grounded in sufficient facts, reliable methodology, and proper application of that methodology to the facts of the case.
Question 5: A forensic examiner is asked by a client to omit unfavorable findings from a report. The examiner should:
- Comply if the client is paying for the report
- Omit the findings only if they are not directly relevant
- Refuse and include all findings regardless of their effect on the client's case (Correct answer)
- Consult with the opposing expert first
Correct answer: Refuse and include all findings regardless of their effect on the client's case
Omitting unfavorable findings constitutes a breach of professional ethics and potentially perjury; examiners must report all material findings.
Question 6: What is the primary purpose of a Daubert hearing in U.S. federal proceedings?
- To determine the credibility of lay witnesses
- To allow the judge to assess whether proposed expert testimony meets reliability standards (Correct answer)
- To schedule the order of expert witness testimony
- To challenge the chain of custody of physical evidence
Correct answer: To allow the judge to assess whether proposed expert testimony meets reliability standards
A Daubert hearing is a pre-trial proceeding where the judge acts as a gatekeeper to evaluate whether an expert's methodology is scientifically reliable.
Question 7: Which constitutional amendment is most directly implicated when a forensic examiner conducts a search of a suspect's digital devices without a warrant?
- First Amendment
- Fourth Amendment (Correct answer)
- Fifth Amendment
- Sixth Amendment
Correct answer: Fourth Amendment
The Fourth Amendment protects against unreasonable searches and seizures, requiring warrants for most digital device searches after Riley v. California (2014).
