Who is classified as a confidential informant?

A confidential informant is typically an individual who provides information to law enforcement agencies about criminal activity, often while seeking to remain anonymous to protect themselves from potential retaliation. In this context, an undercover individual who assists law enforcement fits this definition well. They operate in a way that requires a level of secrecy and confidentiality concerning their identity and the information they supply, which is essential for the success of various investigations.

The first choice regarding a witness in a court case does not align with the classification of a confidential informant since witnesses generally provide testimony publicly in court and are not necessarily involved in covert operations. The third option, a probation officer with insider knowledge, may have access to valuable information but does not inherently serve as a confidential informant unless they engage in undercover operations or share sensitive information in a manner that maintains confidentiality. The final option, a victim providing evidence, also does not fit the definition since victims are typically known parties in a case and provide their information openly rather than anonymously.
