What is one of the uses of surveillance?

Surveillance is a critical tool in criminal investigations, and one of its primary uses is to apprehend criminals during the commission of crimes. This involves observing suspects or criminal activities in real-time to gather evidence that can lead to immediate intervention by law enforcement. By monitoring a scene, officers can capture key moments that can help in securing arrests, documenting criminal behavior, and collecting evidence for prosecution.

In many cases, surveillance can provide law enforcement with vital information about the methods, behaviors, and identities of individuals engaged in criminal activities. This real-time observation is essential for ensuring public safety and effectively addressing criminal behaviors as they occur. While other options like resolving civil disputes, gathering public opinion, and monitoring traffic patterns may involve observational techniques, they do not specifically align with the primary objectives of law enforcement surveillance in the context of criminal investigations.
