"Transparency in Federal Law Enforcement Activities Act"; establishes law enforcement officer identification requirements under certain circumstances.

S 3216, the "Transparency in Federal Law Enforcement Activities Act," requires federal law enforcement officers (such as ICE or CBP agents) operating in New Jersey with state or local law enforcement to visibly display their name and agency on identification and verbally state this information upon request when questioning, detaining, or arresting someone. It applies to all federal agents participating in joint operations with New Jersey agencies. State and local officers must refuse to assist in any operation if federal agents fail to comply, and violations can lead to disciplinary action against officers or private lawsuits for affected residents. The bill clarifies it does not interfere with lawful federal actions but mandates transparency during cooperative law enforcement activities within New Jersey.
