During which type of courts can officers be subpoenaed to testify?

Officers can be subpoenaed to testify in civil courts as well as in various other hearings due to their role as witnesses in legal proceedings. In civil court, law enforcement personnel may provide testimony related to incidents where their involvement was relevant, such as in cases of negligence, personal injury, or disputes that arise between individuals or entities. Beyond civil courts, officers may also be called to testify in administrative hearings, grand jury proceedings, and even in criminal courts when their testimony pertains to a case. The breadth of potential court settings underscores the fundamental role that law enforcement officers play in upholding the legal system and providing crucial testimony that can impact the outcome of a case.
