Which of the following is an example of a forensic investigation method?

The scientific analysis of physical evidence is a crucial aspect of forensic investigation methods because it involves the application of scientific techniques and principles to analyze various types of evidence collected from a crime scene. This can include methods such as DNA analysis, fingerprint examination, toxicology, and ballistic testing. Such analyses provide objective data that can be vital for solving crimes, establishing connections between suspects and victims, and supporting evidence in court.

In contrast, interrogating suspects, community outreach programs, and neighborhood surveillance do not qualify as forensic investigation methods. Interrogation focuses on gathering information from people rather than analyzing physical evidence. Community outreach programs aim to foster relationships between law enforcement and the community, while neighborhood surveillance is more about monitoring activities rather than conducting a scientific analysis of evidence. Therefore, the scientific analysis of physical evidence stands out as the only option that directly pertains to forensic investigation methods.
