Cross-interrogations refer to the process of questioning a witness or suspect by more than one interrogator. To avoid repetition of the term, there are several synonyms that can be utilized. These include cross-examination, joint questioning, joint interrogation, reciprocal questioning, and collaborative interrogation. Cross-examination is a legal term often used in court proceedings when a witness is questioned by both sides. Joint questioning is a term often used in law enforcement investigations, where multiple detectives or agents jointly question a suspect or witness. Collaborative interrogation refers to when interrogators work together to gather information from a suspect. Reciprocal questioning is another term often used in legal proceedings, where the questioning is done in a back-and-forth manner between the parties involved.
