When the prosecution asks a CSI a leading question on direct examination, the CSI should:
Answer: Answer only what is accurate, not what the question implies
CSIs must answer truthfully regardless of how a question is framed; cooperative witnesses still owe accuracy over convenience.
The concept of 'cognitive bias' in forensic investigation most directly threatens which principle?
Answer: Objective, impartial analysis
Cognitive bias causes analysts to unconsciously interpret evidence in a way that confirms pre-existing expectations, undermining objectivity.
A CSI is called to testify but realizes the lab report contains a typographical error in a measurement. The CSI should:
Answer: Correct the error verbally during testimony and flag it for the record
Accuracy in testimony supersedes consistency with a flawed document; errors must be acknowledged and corrected on the record.
Which of the following best describes 'tunnel vision' in a criminal investigation?
Answer: Focusing on one suspect while ignoring contradictory evidence
Tunnel vision occurs when investigators fixate on a theory or suspect and discount evidence pointing elsewhere, risking wrongful prosecution.
If opposing counsel attempts to impeach a CSI's testimony using a prior publication the CSI authored, the CSI should:
Answer: Acknowledge the publication and explain any context or updated science
Owning prior statements and contextualizing them demonstrates integrity; denial or evasion severely damages credibility.
A Daubert hearing is conducted to determine:
Answer: Whether expert testimony meets standards of scientific reliability
Under Daubert v. Merrell Dow Pharmaceuticals, federal courts assess methodology, peer review, error rate, and general acceptance before admitting expert testimony.
When a CSI's testimony conflicts with another forensic expert's testimony in the same case, the CSI should:
Answer: Explain the basis for their own findings without attacking the other expert
Each expert testifies to their own findings and methodology; deference or capitulation without scientific justification compromises integrity.
