Does an informant have to testify against you if they set you up?

Whether an informant has to testify against you depends on the circumstances of the case and the jurisdiction. In many instances, informants may be required to testify if their testimony is deemed essential to the prosecution's case. However, there are situations where informants may be granted immunity or protection, allowing them to avoid testifying. It's crucial to consult a legal professional for specific advice related to individual cases.
