Isn't there a law stating that a parole officer can not hold married people apart?

There is no specific law that universally states that a parole officer cannot hold married people apart. The conditions of parole can vary widely depending on the jurisdiction, the specifics of the case, and the nature of the offense. Parole officers have discretion to impose certain conditions on parolees, which may include restrictions on who they can associate with, including spouses, particularly if that person is viewed as a potential influence on the parolee's behavior. However, laws and regulations regarding parole can differ from one location to another. If you're seeking information about a specific case or jurisdiction, it might be best to consult a legal expert or an attorney who specializes in criminal law or parole issues.
