How is an informant best defined?

An informant is best defined as a non-law enforcement individual who provides information to law enforcement. This definition captures the essence of what an informant does, which is to provide valuable information that can aid in investigations, typically in exchange for some form of consideration, such as money or protection. Informants often have insider knowledge about criminal activity that is not accessible to law enforcement officers.

While other terms in the choices may describe individuals involved in intelligence or undercover operations, they do not accurately capture the broad role of an informant. For instance, law enforcement officers who gather information secretly are typically referred to as undercover officers, not informants. Confidential sources within the community could potentially refer to informants, but the definition is narrower and could imply a more formalized relationship than what is typically meant by an informant. An undercover agent posing as a civilian is also a specific role that differs significantly from that of an informant, as it involves law enforcement individuals engaging directly in criminal environments for investigative purposes.
