What is described as the knowledge gathered from individuals and legitimate sources in a criminal investigation?

The correct answer is "Information" because in the context of a criminal investigation, information refers to the intelligence or insights obtained from interviews with individuals, analysis of reports, and other legitimate sources. It encompasses all the details that investigators accumulate during the process, which can help in understanding the context of a crime, identifying potential suspects, and piecing together the sequence of events.

This distinction is relevant, as evidence refers specifically to material or physical items that can be used to prove or disprove facts in court, while testimony is the firsthand account provided by witnesses or experts during legal proceedings. Data, on the other hand, typically refers to raw facts and figures that can be analyzed but do not necessarily provide context or clarity in the way information does within an investigation. Thus, the term "information" accurately captures the broad spectrum of gathered insights that assist in criminal investigations.
