It depends. If an officer accidentally leaks your name when you requested anonymity, that may not be enough to take legal action. However, if you can prove that he or she intentionally mentioned your name in an attempt to put your safety at risk, then you may have a case. For example, if you gave the police information leading to a suspect’s arrest, and this suspect threatens to kill the person who gave the police this information, or threatens to have this person killed, and despite the officer’s knowledge of these statements, he or she revealed your name to the media, then you may have a case.
