What term describes methods for monitoring suspects or crime scenes?

• A. Testimonial Evidence
• B. Interview Techniques
• C. Surveillance Techniques
• D. Forensic Techniques

Answer: (C)

Surveillance techniques are the methods used to monitor suspects or crime scenes. This includes watching, following, or recording movements over time—whether through cameras, undercover stakeouts, or other monitoring methods. The focus is on gathering information by observing behavior and locations rather than collecting statements or analyzing evidence in a lab. This is different from testimonial evidence, which comes from what someone says; from interview techniques, which are about eliciting information through questioning; or from forensic techniques, which involve scientific analysis of physical traces. Surveillance directly addresses monitoring activities to build a case or secure safety.
