ETC ETC Courtroom Testimony & Legal Procedures 1 — Questions and Answers
Question 1: When an evidence technician testifies in court, what is the primary purpose of their testimony?
- To present factual observations and technical findings objectively without offering opinions beyond their expertise (Correct answer)
- To advocate for the prosecution's theory of the case
- To explain the defendant's motive based on evidence collected
- To summarize witness statements gathered during the investigation
Correct answer: To present factual observations and technical findings objectively without offering opinions beyond their expertise
An evidence technician testifies as a fact witness or limited expert, presenting objective observations and technical findings relevant to how evidence was collected and processed.
Question 2: What is the Frye standard in relation to scientific evidence admissibility?
- Scientific evidence is admissible if the methodology is generally accepted in the relevant scientific community (Correct answer)
- Scientific evidence is admissible if the judge determines it is reliable based on specific criteria
- Scientific evidence only requires peer review to be admissible
- Any scientific test result is automatically admissible as documentary evidence
Correct answer: Scientific evidence is admissible if the methodology is generally accepted in the relevant scientific community
The Frye standard holds that scientific techniques must be generally accepted by the relevant scientific community to be admissible; some states still use Frye while federal courts use Daubert.
Question 3: Under the Daubert standard, what factors does a judge consider to admit scientific evidence?
- Whether the theory is testable, peer-reviewed, has a known error rate, and is generally accepted in the field (Correct answer)
- Whether the evidence was collected by a certified technician only
- Whether the defense attorney objects to the evidence's admissibility
- Whether the evidence is relevant and collected with a valid warrant
Correct answer: Whether the theory is testable, peer-reviewed, has a known error rate, and is generally accepted in the field
Daubert (adopted by federal courts) requires judges to evaluate testability, peer review, known error rate, and general acceptance in the relevant scientific community.
Question 4: What is a subpoena duces tecum and how does it relate to an evidence technician's duties?
- A court order requiring the technician to produce specific records, reports, or physical evidence for court (Correct answer)
- A warrant authorizing collection of evidence at a specific location
- A legal document exempting the technician from testifying in sensitive cases
- An authorization form for lab analysis of controlled substances
Correct answer: A court order requiring the technician to produce specific records, reports, or physical evidence for court
A subpoena duces tecum commands a person to bring specific documents or evidence to court; evidence technicians may receive one requiring them to produce reports, chain of custody records, or physical exhibits.
Question 5: Before testifying, an evidence technician should review which documents to prepare for court?
- Their written reports, chain of custody forms, photographs, and any notes taken at the time of collection (Correct answer)
- Only the prosecutor's summary of evidence
- The defendant's criminal history and prior convictions
- The final verdict from a similar prior case
Correct answer: Their written reports, chain of custody forms, photographs, and any notes taken at the time of collection
Reviewing original reports, chain of custody records, photographs, and contemporaneous notes ensures the technician's testimony is accurate and consistent with documented findings.
Question 6: What should an evidence technician do if they are asked a question in court that they do not know the answer to?
- Honestly state 'I don't know' rather than speculating or guessing (Correct answer)
- Provide their best estimate based on general knowledge
- Defer the question to the prosecuting attorney
- Ask to consult their notes before answering any further questions
Correct answer: Honestly state 'I don't know' rather than speculating or guessing
Saying 'I don't know' when genuinely uncertain is the only appropriate response; speculation or guessing in court can damage credibility and the validity of evidence.
