Which concept means verify statements with physical evidence?

Which concept means verify statements with physical evidence?

• A. Corroborate Witness Accounts
• B. Observation Return
• C. Surveillance Types
• D. Legal Authority

Answer: (A)

Corroboration is the process of confirming statements by securing independent physical or documentary evidence. By lining up what a witness says with tangible proof—fingerprints, DNA, video, receipts, or other records—investigators validate testimony beyond memory or perception, boosting reliability and reducing bias. The other terms don’t capture this verification role: observation return isn’t a standard concept for validating statements, surveillance types describe monitoring methods rather than proving what was said, and legal authority concerns power to act rather than how statements are verified.
