What is the primary benefit of using surveillance in law enforcement investigations?

The primary benefit of using surveillance in law enforcement investigations is that it allows officers to gather evidence discreetly and effectively. Surveillance techniques can provide critical insights into criminal behavior, establish patterns, and document activities that may be relevant to an investigation. This method of gathering information is often less intrusive than other forms of investigation and can lead to the collection of data that is essential for building a strong case against suspects.

Moreover, surveillance can help law enforcement observe suspects without their knowledge, thus enabling officers to capture authentic behaviors and interactions that might not be revealed through interviews or other investigative methods. This kind of information can be pivotal in prosecutions, helping to establish timelines, identify accomplices, and corroborate witness statements.
