Criminal Psychology

Girl, please don't live in the humble grave.

"Mr. Lin, I will ask you some questions below, please answer truthfully."

"Ok."

"Are you Lin Chen?"

"Yes."

"Are you Fengchun?"

"Yes."

"Are you willing to answer my question truthfully about this polygraph survey?"

"willing."

Lin Chen was sitting in the interrogation room. He had several clips on his index finger and ring finger, a blood pressure monitor wrapped around his arm, and some wires connected his chest and the screen on the desktop.

His heartbeat, breathing, blood pressure, skin electricity, and other parameters are gathered into complex lines on the screen and slowly advanced forward.

Opposite him is a staff member of the Inspectorate, of course, not Inspector Huang himself.

Since the "Candy Thieves" case, Lin Chen has never seen Huang Ze again for some reason, and, for no apparent reason, Huang Ze actually sent someone to handle the police approval process for him. Of course, before that, he still had to explain something unexplained.

Of course, passing the polygraph test is also part of the explanation process.

The polygrapher opposite him looked away from the data monitoring screen, his eyes were slightly fixed, and of course, after ending the neutral problem without threat, of course, he got to the topic.

"Did you use your authority to help criminals in the process of handling the case?"

"No."

"During the process of assisting the police in the 9.10 serial killings, did you intend to help the suspect Feng Peilin jump off the river to escape?"

"No."

The data line on the screen began to fluctuate, and the polygrapher quickly swept across the screen, then slightly disappointed back to look: "What happened to Feng Peilin after you fell into the river with Feng Peilin?"

"After falling into the river with Feng Peilin, we were scattered by the river. I don't know if he is still alive." Lin Chen held the glass, the water was hot, and a thin layer of tea floated on the water surface. He stared at the rotating tea stalk. Replied lightly.

"According to you, since you are okay, why not return to the team to report these situations before leaving, but instead of saying hello and leaving alone, sneak away?"

Hearing this question, Lin Chen raised his eyes slightly, as if looking at the face of the polygrapher, as if looking at the clear one-way glass behind him.

"Since Feng Peilin's goal has always been me, I'm afraid it will cause unnecessary trouble to the police again." He paused, and then continued: "And some powerful people are always asking me for trouble , I also want to swindle to death, to avoid these troubles. "He was very stable, his voice was calm, because it sounded extraordinarily calm.

Even if he doesn't look at the complicated lines, from the tone or attitude of his speech, anyone who hears this sentence will feel that there is nothing wrong with this reason, but it is just nothing wrong.

Standing outside the one-way glass that was a little too clear, stood alone.

He put his hands in his pockets and wore the standard police uniform, which was different from the meticulous Inspector Huang who always wore clothes. His clothes were a bit wrinkled and the first button was not tied up. But maybe his eye sockets are too deep, or his eyes are greenish. In his eyes staring at the interrogation room, there is a sense of tranquility and peace that is not in harmony with the diffuse image.

But it ’s just that kind of tranquility and deep meaning, only kept it for a short time. After hearing that very reasonable answer, he originally twitched gently to keep the corner of his mouth serious, and the dark green eyes rippled, Then he laughed and looked at the polygraph on the table.

Well, the indicators are stable, so his smile is getting deeper and deeper.

The polygrapher turned a page and asked, "Have you ever been in a relationship?"

Rao is Lin Chen, and there are some surprises about such a question: "Huh?"

"Answer the question." The polygrapher cleared his throat and said solemnly.

"No."

"Have you never liked anyone?" If he thought the answer was too strange, he could not help asking.

"No."

At this moment, the data on the monitor screen finally showed visible fluctuations, and those who answered the question quickly realized that they had lied on the question.

He frowned slightly, as if he didn't expect that he would actually have a problem with this answer.

But in the end, what went wrong?

Although the subjects began to struggle, the polygrapher quickly turned over this chapter. After all, who doesn't have some *?

The polygrapher continued to return to the topic: "So from the dossier, in the candy thief case, you happened to be on a hijacked bus, right?"

"Yes."

"Where are you going by car?"

"Go travel."

"What a coincidence ..."

The polygrapher said subconsciously that at this moment, Lin Chen could not help but let go of the tea cup and said, "Sorry, please allow me to interrupt you."

"what happened?"

"I just listened to these questions you asked. I think the polygraph program you use should be the cqt criterion polygraph ..."

The polygrapher turned to the first page of the document and glanced at it, a little awkwardly.

"The lie detection method for the guideline problem is divided into four parts, neutral question, guideline question, related question, and extra-question question. For example, asking the name and age are neutral questions. The role of the neutral question is to establish a normal level of response. , So during the questioning process, please try to ask the testee to answer a 'yes' question and a 'no' question, otherwise there will be problems with the baseline setting.

The polygrapher closed the file and listened helplessly.

"At the same time, when you ask questions related to the case, please try to write the pattern of the question as a pattern that allows the testee to answer whether or not the item. The two questions you asked at the beginning are good, but later become After all, interrogation, interrogation and polygraph are still different. "

The polygrapher opened his mouth and found himself speechless.

But Lin Chen's words obviously haven't finished yet: "In fact, in a set of cqt polygraph questions, it is best to involve only one aspect and one question, and to repeatedly determine whether the subject is lying, so The case of the candy thief is another matter. You better put it in the next set of questions and ask me again. "

Lin Chen's counterattack was quick and relentless.

The mixed-race young man standing behind the one-way glass almost laughed out loud. Some people were so cute when they got angry when they answered wrong questions.

"Mr. Lin, I understand." The lie detector sighed, stood up, and took off the wires sticking to Lin Chen. "If you lie sincerely, the instrument can't detect it."

"..."

"This is just a routine procedure. If you answer me a few more questions, we will stop working."

"Excuse me."

"I read the file of 'The Candy Thief'. As an ad hoc negotiator, you made great efforts in persuading Fang Aizi, but at the same time, you were also one of the last people who had contacted Yang Dianfeng. After that, The police car that Yang Dianfeng was riding on was fitted with a sucker bomb. Under the circumstances, do you think Yang Dianfeng had time to give the information about his arrest to criminals? "

"No, he didn't have any chance to contact a series of communication tools such as mobile phones at the time, and Yang Dianfeng knew very well that once he was arrested, seeking asylum was the only way out."

"Because the reaction of the criminals was very fast at that time, since it was not the criminals notified by Yang Dianfeng himself, can I make an inference that among all the people on the scene, someone passed the information directly to the criminals, so that the criminals could quickly React and kill. "

"I do not rule out this possibility, but in fact, I can also think that Yang Dianfeng itself is closely monitored by the criminal organization, and if he has a problem, he will be quickly eliminated."

"Please answer my question positively and answer whether I can make this inference." The polygrapher interrupted him suddenly and asked very seriously.

"Yes," Lin Chen answered for a moment.

"Continuing the question just now, you are the most professional and systematic psychologically trained expert at the crime scene, then did you detect any strangeness at that time, and of all, you doubt who is most likely to pass this information to Criminals? "

Hearing this question, Lin Chen suddenly looked up.

The two questions in this sentence are really full of the style of the Inspectorate, full of conspiracy and traps, and even very likely. These questions themselves were drafted by Huang Inspector himself.

Originally, the existence of the Inspectorate was to supervise the correct and proper exercise of power by police officers during the handling of the case. Since the Inspectorate suspected that there were leaks inside the police, of course, it was necessary to start an investigation, but based on the possibility of reasoning, it had to be With deterministic results, it is a little bit worrisome to use such bare questions to encourage reporting.

"I did have professional psychological training, but I am not a professional facial expression recognition expert, and even the most professional facial expression recognition expert needs to observe and talk carefully to find abnormal problems. You ask me, in my face The other side, Ai Zi, when all the police officers are hidden in the reeds, have I found someone with a bad heart on the scene, then I can only answer you, I don't have the ability to find this question. "

———

The review process is always lengthy and tedious.

When Lin Chen walked out of the police gate, it was already dark. In the early spring night, the wind was as soft as the starry sky.

Xing Cong leaned against the stone pillar at the door and was smoking a cigarette. When he saw Lin Chen, he stood slowly and straightened: "Are you going well?"

Lin Chen shook his head, handed the result just now.

Xun Lian's face sank, biting his cigarette butt, and quickly turned over the report. His eyes fell on the last line of the report.

It was clearly written above that the word "approved".

The head of Xun Cong couldn't help but put his hand on Lin Chen's head and rubbed it: "Hey, didn't this pass, why shook his head?"

"You didn't ask me, did you go well?"

"All passed, isn't it smooth?"

"I just thought that Huang Ze would suddenly relax and really let me pass the consultant's review. This is too strange."

Looking at Lin Chen's slightly worried face, Xun Conglian showed a meaningful smile: "What if the conscience found out?"

He took a breath and asked with a smile.
