Which individual usually possesses the most significant information regarding an incident?

The individual who typically has the most significant information regarding an incident is the suspect. This is because the suspect is directly involved in the incident and has firsthand knowledge of what transpired. They may have information about their own actions, motives, and interactions with other parties involved, which can be crucial in understanding the full context of the event.

While witnesses and victims can provide valuable insights and perspectives, their information may be limited by what they observed or experienced. A witness might only see parts of the incident without knowing the motivations behind actions, while a victim might not have insight into the suspect's thought process or intentions. Law enforcement officers, on the other hand, gather information and evidence, but they rely on statements from those directly involved to build a complete picture. Thus, it is often the suspect who possesses the most direct knowledge of the incident as they can recount the details surrounding their involvement.
