CFL CFL Industry Standards 3 — Questions and Answers
Question 1: Under the Federal Rules of Evidence, Rule 702, an expert witness's testimony must be based on sufficient facts, reliable methodology, and:
- Application of principles reliably to the case facts (Correct answer)
- Personal opinion unsupported by data
- Hearsay evidence obtained secondhand
- Conclusions drawn solely from experience without testing
Correct answer: Application of principles reliably to the case facts
FRE 702 requires that expert testimony be the product of reliable principles and methods applied reliably to the specific facts of the case.
Question 2: An RSC (Residential Security Container) rating for a safe primarily certifies resistance to which type of attack?
- Pry-bar and hand-tool attacks for 5 minutes (Correct answer)
- Torch and drill attacks for 30 minutes
- High-velocity impact from bullet rounds
- Flooding and water immersion for 1 hour
Correct answer: Pry-bar and hand-tool attacks for 5 minutes
The RSC rating, established by UL's burglary classifications, means the safe can withstand common pry-bar and hand-tool attacks for at least 5 minutes.
Question 3: When testifying about lock bypass, a forensic locksmith should describe their methodology as:
- Peer-reviewed and reproducible by other qualified examiners (Correct answer)
- Proprietary and unavailable for opposing review
- Based solely on personal field experience
- Derived exclusively from manufacturer specifications
Correct answer: Peer-reviewed and reproducible by other qualified examiners
Under Daubert standards, methodology must be peer-reviewed and reproducible so courts can assess its reliability independently.
Question 4: ADA (Americans with Disabilities Act) Standards require door hardware to be operable with which type of action?
- One hand without tight grasping, pinching, or twisting (Correct answer)
- Two-hand simultaneous lever depression
- Key-only access without thumb-turn activation
- Magnetic card swipe with no manual component
Correct answer: One hand without tight grasping, pinching, or twisting
ADA requires that accessible door hardware be operable with one hand and not require tight grasping, pinching, or wrist twisting.
Question 5: The Daubert standard replaced which earlier legal standard for admissibility of scientific expert testimony in federal courts?
- Frye standard (Correct answer)
- Kumho standard
- FRE 404 standard
- Brady standard
Correct answer: Frye standard
The 1993 Daubert decision replaced the Frye 'general acceptance' test with a more flexible reliability-based standard for scientific testimony.
Question 6: In forensic locksmithing, 'impressioning marks' on a key blank are significant because they:
- Indicate the blank was used to create a working key by feel (Correct answer)
- Prove forced entry occurred through a keyway
- Show the lock was serviced by a licensed locksmith
- Demonstrate the lock is a high-security model
Correct answer: Indicate the blank was used to create a working key by feel
Impressioning marks are file marks left on a key blank as it is worked in the lock, indicating someone created a working key without an original.

- High security cylinders (Correct answer)
- Exit devices and panic hardware
