Xu Jiuyan continued: "This layout can create a sense of nowhere to hide, strange and isolated, thus reinforcing the suspect's sense of "let me out" during the interrogation. The one-way see-through mirror is an ideal addition to the interrogation room, as it not only increases the suspect's anxiety, but also allows other police officers to observe the interrogation process and helps the interrogator determine which techniques work and which don't. ”

Yu Shuhui snorted and said, "Aren't all nonsense you say?" That's what the first class of the police academy talked about, and my question is that I want you to solve this problem, not for you to tell me how to solve it. ”

Tian Yuming smiled and said, "It's a bit interesting to continue." ”

Xu continued: "Before the nine-step process of Reed's interrogation begins, a first meeting will be scheduled to determine whether the suspect is guilty or not. In the first meeting, the interrogators tried to create a non-threatening atmosphere with casual conversations, thus establishing a friendly and trusting relationship between themselves and the suspect. People prefer and trust those who are similar to themselves, so the police may ask to share certain interests or beliefs of the suspect. If a suspect starts talking to the interrogator about something innocuous about it, it will be difficult for him to stop talking or start lying when the discussion turns to crime.

In the first meeting, the police built a baseline response before they began to apply real pressure by observing the suspect's reactions, both verbal and nonverbal. The police will then use this benchmark as a reference point.

The method of benchmarking involves asking the suspect various questions that allow him to use different parts of his brain. The police will ask inconsequential questions, some to recall, some to think about. When the suspect recalls something, his eyes often move to the right. This is the external manifestation of his brain being stimulating the memory center. When he is thinking about something, his eyes move up or to the left, which is a reflection of what his cognitive center is doing. The police need to keep these eye movements of the suspect in mind.

The next step is to question the suspect. The police officer will first ask a few basic questions about the facts of the crime and compare the suspect's reaction to the benchmark to determine whether he is telling the truth or lying. If the interrogator asks where the suspect was on the night of the crime, and the suspect answers truthfully, the suspect recalls the night and his eyes move to the right; If he is making up an alibi confession, then he will think, and his eyes will move to the left because of it. If the interrogator determines that the suspect's reaction indicates that he is lying and that all other evidence proves his guilt, then the interrogation of the guilty suspect will begin.

The police state the facts of the suspect's crime and inform him that evidence against the suspect has been obtained. The evidence may be real or it may be fabricated. The police will generally state the course of the case in a confident tone, indicating that the suspect has been determined to have been involved in the crime. As a result, the psychological pressure of the suspect began to increase. At the same time, the interrogator can walk around the room and invade the suspect's private space, thereby further increasing the latter's discomfort. ”

"Isn't that an inducement?" Yu Shuhui retorted.

After all, Xu Jiuyan is a professional lawyer, and Xu Jiuyan explained with her legal knowledge: "The so-called inducement of confession is an illegal interrogation act in which investigators violate relevant laws and regulations and use fraud, inducement, illegal promises and other means to trick criminal suspects into confessing to their crimes. The use of improper and illegal means to interrogate criminal suspects not only fails to safeguard the dignity of the law and the authority of the state's judicial organs, but on the contrary, the illegality of the interrogation results leads to the illegality of the interrogation results, and the confessions obtained as a result have no evidentiary effect. Therefore, the legitimacy of the interrogation strategy and the illegality of confession and inducement are the essential differences between the two. ”

Tian Yuming took the lead in applauding and said, "Sure enough, he is a rising star of criminal psychology portraitists in Nanyi City, and he is really useful." ”

Xu Jiuyan said a little shyly: "I just said what I thought." ”

Tian Yuming encouraged: "Come on, come on, everyone quickly memorize it, these skills that Officer Xu said are much more useful than the clichés in the textbooks of the police academy." ”

"If the suspect starts to be agitated, lick his lips, or tidy up his appearance, such as holding his hair with his hands, the police will see these small details as a hint that the suspect is lying, and can be sure that the police are going in the right direction for the interrogation," Xu continued.

The interrogator will make up a story about why the suspect committed the crime. The theme is to look into the eyes of the suspect to speculate on why he committed the crime, why the suspect is willing to think that the crime was his doing, and what kind of reasons can make the suspect confess. Does the suspect use a particular mode of reasoning more often than anyone else?

For example, does he seem willing to blame the victim for the crime? The police devise a theme so that the suspect can use the theme to excuse or justify his involvement in the crime, and then the police observe the suspect to determine whether the latter likes the subject matter or not. Did he listen more attentively than before? Is he nodding? If so, the police will continue to make it up along the subject; If not, he'll switch to a different theme and start over. The subject matter is hidden behind the interrogation process and continues throughout. In compiling the subject, the interrogator's tone is soft and gentle, and the suspect does not feel threatened in the slightest, leading the suspect into believing that he is safe.

Getting a suspect to deny his guilt increases his confidence, so the police will try to interrupt all the suspect's denial of the crime, sometimes telling the suspect that he will be given a chance to speak for a while, but now he needs to listen to the police. From the beginning of the interrogation, the police will be aware of the suspect's intention to deny the crime and stop him before he can speak. Preventing a suspect from denying the guilt, in addition to keeping his confidence low, also keeps the suspect quiet, so there is no opportunity to seek legal help. If the suspect does not deny it during the preparation of the subject, the police will take this as a signal to establish the suspect's guilt. If, at the time of the preparation of the subject, the initial attempts at denial faded or stopped, the interrogator knew that he had found a good subject and that the suspect was getting closer to confessing.

After the interrogator has fully compiled a topic involving the suspect, the suspect may present a logical rebuttal rather than a simple denial, and if handled properly by the police, the suspect's rebuttal will be more akin to a guilty plea. At this point, the suspect will feel discouraged and undecided. He may want to find someone to help him out of this situation. ”
