Which option best defines canvass in investigations?

• A. A form of search of CCTV footage.
• B. A post-arrest procedure.
• C. A surveillance operation after the incident.
• D. An inquiry of all possible sources of information surrounding the incident or crime scene.

Answer: (C)

Canvass is a broad, rapid information-gathering effort aimed at all possible sources surrounding an incident or crime scene. Its purpose is to uncover what happened by reaching out to people who may have witnessed something, heard something, or have information that can help reconstruct timelines and identify leads. This involves talking with neighbors, bystanders, shop owners, delivery personnel, and others who were in the area, not spying on individuals or reviewing video after the fact. The goal is to map out known facts and uncertainties so investigators can plan the next steps. In this sense, canvassing is distinct from looking through CCTV footage (that’s a targeted media search), from post-arrest procedures (which occur after arrest), or from surveillance operations after an incident (which involve watching or tracking people). The defining idea is gathering information from all plausible sources related to the incident or scene.
