In which situation is it advisable to utilize more than one investigator?

Utilizing more than one investigator is advisable in situations where multiple days of surveillance are required. This approach helps ensure comprehensive coverage and reduces the risk of missing critical information or events that may unfold over an extended period. Multiple investigators can provide a team-based view of the surveillance, allowing for more effective monitoring and note-taking, as well as sharing responsibilities such as rotating shifts to maintain vigilance and objectivity. This method enhances overall efficiency and effectiveness in gathering evidence and maintaining continuity.

In contrast, a single investigator might miss important details or become fatigued over long durations of surveillance, impacting the quality of the investigation. Therefore, when significant time and resources are dedicated to observing a suspect, having additional personnel on hand becomes crucial for the success of the operation.
