Interrogation techniques are methods used by law enforcement and intelligence agencies to gather information from individuals. These techniques can include building rapport, asking open-ended questions, and using psychological strategies to encourage cooperation. The goal is to obtain truthful and useful information while respecting legal and ethical standards. Some common techniques involve the use of mirroring body language, active listening, and creating a comfortable environment. Other methods may include presenting evidence or using deception to elicit a response. Each technique aims to facilitate communication and uncover facts without resorting to coercion or violence.
