What is required for an unnamed informant's information to be included in an affidavit?

For the information provided by an unnamed informant to be included in an affidavit, the credibility of the informant is essential. When law enforcement officers seek to establish probable cause for a warrant, the reliability of the informant's information carries significant weight. Courts often require that there be a basis to demonstrate that the informant is credible and that the information they provide is trustworthy. This can be assessed through various means, such as corroborating evidence, the informant's past reliability, or details that indicate insider knowledge about the matter at hand. Without establishing this credibility, the inclusion of the informant's information may be challenged in court, potentially undermining the legal proceedings.
