CFL Legal & Ethical Considerations in Forensics 2 — Questions and Answers
Question 1: Under the Daubert standard, what is the primary criterion a federal court uses to determine the admissibility of forensic expert testimony?
- The expert's years of professional experience
- Whether the methodology is scientifically valid and has been tested (Correct answer)
- Whether the expert holds a state-issued license
- Whether the testimony was challenged by opposing counsel
Correct answer: Whether the methodology is scientifically valid and has been tested
Daubert requires that expert testimony be grounded in a reliable, tested, and peer-reviewed scientific methodology.
Question 2: A forensic locksmith is subpoenaed but believes disclosing client information would harm an ongoing police investigation. What is the correct course of action?
- Refuse the subpoena entirely based on client confidentiality
- Comply with the subpoena and notify the client's attorney and relevant law enforcement immediately (Correct answer)
- Destroy the records to protect the investigation
- Request a continuance indefinitely until the case closes
Correct answer: Comply with the subpoena and notify the client's attorney and relevant law enforcement immediately
A forensic locksmith must comply with a lawful subpoena while promptly notifying appropriate parties so legal remedies such as a protective order can be sought.
Question 3: Which Fourth Amendment doctrine most directly governs whether a forensic locksmith's physical examination of a lock constitutes an unlawful search when conducted at law enforcement's request?
- The plain view doctrine
- The exclusionary rule
- The third-party doctrine (Correct answer)
- The fruit of the poisonous tree doctrine
Correct answer: The third-party doctrine
The third-party doctrine holds that information voluntarily shared with a third party (here, the locksmith acting for police) loses Fourth Amendment protection.
Question 4: When a forensic locksmith discovers evidence of a crime not related to the case being investigated, the ethical obligation is to:
- Photograph it and continue the assigned examination without comment
- Immediately halt work, secure the scene, and notify the retaining attorney or law enforcement (Correct answer)
- Document it in a private notebook but omit it from the formal report
- Collect the evidence personally to preserve it
Correct answer: Immediately halt work, secure the scene, and notify the retaining attorney or law enforcement
Discovering incidental evidence requires stopping further action and reporting to the proper authority to preserve both the evidence and the legal chain of custody.
Question 5: Which of the following best describes a forensic locksmith's duty of impartiality?
- Presenting findings that favor the retaining party
- Providing objective opinions regardless of which party is paying the fee (Correct answer)
- Declining to testify if the findings harm the client
- Sharing preliminary opinions only with the retaining attorney
Correct answer: Providing objective opinions regardless of which party is paying the fee
A forensic expert's duty runs to the court and truth, not to the party paying for services; biased opinions violate professional and ethical standards.
Question 6: An attorney asks a forensic locksmith to revise a written report to remove conclusions unfavorable to the client. The locksmith should:
- Revise the report as requested since the attorney is the client
- Refuse to alter factual findings or conclusions, even if asked by the retaining counsel (Correct answer)
- Issue two versions — one for the attorney and one for the court
- Amend the report only if additional payment is provided
Correct answer: Refuse to alter factual findings or conclusions, even if asked by the retaining counsel
Altering or omitting factual conclusions at an attorney's request compromises expert integrity and may constitute obstruction of justice.
Question 7: In a civil case, the standard of proof required for a forensic locksmith's opinion to support a verdict is:
- Beyond a reasonable doubt
- Clear and convincing evidence
- Preponderance of the evidence (more likely than not) (Correct answer)
- Probable cause
Correct answer: Preponderance of the evidence (more likely than not)
Civil cases use the preponderance of the evidence standard, meaning the expert's opinion need only be more probably true than not.
