Which type of informant is defined as having personal knowledge of the information?

A named informant is characterized by possessing personal knowledge of the information they provide, which enhances the credibility and reliability of their accounts. This type of informant has willingly come forward, often identifying themselves, and is typically viewed as more trustworthy because they can be directly held accountable for their disclosures. Their personal connection to the information means that law enforcement can follow up and verify details based on the informant's firsthand experience or observations.

In contrast, unnamed informants may share valuable tips but do so without revealing their identity, which can limit the ability to assess their credibility fully. Anonymous informants provide information without any identification, making it challenging to evaluate their reliability or motivations. A witness informant, while similar to a named informant in having knowledge, may not always be willing to cooperate with law enforcement in the same manner. Therefore, the clarity and accountability associated with a named informant distinctly set them apart from the others in terms of the personal knowledge of the information they possess.
