Which of the following is NOT a governmental investigative tool?

Bonus programs are not considered a governmental investigative tool because they are typically incentives or rewards offered to employees or organizations for achieving specific performance metrics or compliance goals. In contrast, requests for interviews, subpoenas, and search warrants are all formal mechanisms used by government agencies to gather information or evidence during investigations.

Requests for interviews allow investigators to speak directly with individuals who may have knowledge pertinent to an investigation. Subpoenas are legal documents that compel an individual or organization to provide testimony or produce evidence; they are a critical tool for obtaining necessary information that may not be freely provided. Search warrants authorize law enforcement to search specific locations for evidence connected to a suspected unlawful activity, ensuring compliance with legal standards.

Thus, the distinction lies in the nature and purpose of these tools, with investigative tools focused on gathering evidence or information, whereas bonus programs serve a different function related to performance incentives rather than investigation.
