"Informers privilege" refers to the legal protection given to individuals who provide information to law enforcement officials. This privilege allows informers to remain anonymous and not be compelled to testify in court. However, there are several synonyms for this term, including "confidential informant privilege," "informer's immunity," and "protective informant privilege." These terms all refer to the same idea, that informants have a certain level of protection when they choose to provide information to law enforcement. This protection is important in maintaining the safety and anonymity of informants, as well as encouraging individuals to come forward and provide valuable information to help solve crimes.
