Tennessee SB1464 mandates that state and local governmental entities keep certain information related to federal and state immigration enforcement confidential, including the identities of officials involved and details of operational activities. It affects all state and local officials, particularly mayors and law enforcement officers, by imposing penalties for the unlawful release of this information, including Class E felonies for criminal negligence. The bill also revises existing laws regarding the confidentiality of law enforcement personnel information, increasing penalties for negligent disclosures and establishing new classifications for offenses related to the release of information about undercover officers.
