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

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

"Hmm."

"Is your name Lin Chen?"

"Yes."

"Are you from Fengchun?"

"Yes."

"Would you like to answer my questions honestly about this polygraph investigation?"

"Yes."

Lin Chen sat in the interrogation room, his index and ring fingers with a few clips between them, a blood pressure monitor wrapped around his arm, and some wires connecting his chest to the screen on the table.

His heartbeat, breathing, blood pressure, skin electrodermal and other parameters converge into complex lines on the screen and slowly move forward.

Across from him was a staff member of the Inspectorate, not Inspector Wong himself, of course.

Since the "candy thief" case, for some reason, Lin Chen has never seen Huang Ze again, and for some reason, Huang Ze really sent someone to handle the approval procedures for the police consultant for him, of course, before that, he still had to explain some unexplained things clearly.

Of course, the polygraph test is also part of the confession procedure.

The polygraph man across from him took his eyes off the number monitor screen, his gaze slightly condensed, and after finishing the neutral question that was not threatening, of course, he had to get to the point.

"In the course of handling the case, have you ever used your power to help criminals?"

"Nope."

"In the process of assisting the police in handling the 9.10 serial murder case, did you intend to help the suspect Feng Peilin jump into the river and escape?"

"Nope."

The number lines on the screen began to fluctuate, and the polygraph quickly swept across the screen, and then moved back to his gaze with a little disappointment: "What happened after you and Feng Peilin fell into the river together, and whether Feng Peilin was alive or dead?" ”

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

"According to what you say, since you are fine, why don't you return to the team and report these situations before leaving, but do not greet and leave, and sneak away alone?"

Hearing this question, Lin Chen raised his eyes slightly, as if he was looking at the face of the lie detector, and seemed to be looking at the clear one-way glass behind him.

"Since Feng Peilin's target has always been me, I am afraid that if I appear again, it will bring unnecessary trouble to the police." He paused, then continued: "Moreover, some powerful people are always looking for trouble with me, and I also want to cheat to death to avoid these troubles. "His breath is steady, and his voice is calm, because it sounds very calm.

Even if you don't look at those complicated lines, just from the tone or attitude of his speech, anyone who hears this sentence will feel that there is nothing wrong with such a reason, but it is just that there is no problem.

Outside the excessively bright one-way glass, there stood a man.

He has his hands in his pockets, wearing a standard police uniform, unlike Inspector Huang, who is always meticulous in his clothes, the corners of his clothes are a little wrinkled, and the first button is not fastened, so it looks very casual and casual, but maybe his eye sockets are too deep or his eyes are green, and the eyes that are staring at the interrogation room have a quiet and awe-inspiring deep meaning that does not match the casual image.

But that kind of tranquility and deep meaning only lasted for a short time, and after hearing that very reasonable answer, the corners of his mouth that had been trying to keep Yan Sù slightly hooked, and ripples rippled in his dark green eyes, and then he smiled while looking at the lie detector on the table.

Well, all the indicators are very stable, and as a result, his smile is getting deeper and deeper.

The polygraph turned a page and suddenly asked, "Have you ever been in love?" ”

Rao is Lin Chen, and he was also a little surprised by such a question: "Huh? ”

"Answer the question." The polygraph cleared his throat and said very sternly.

"Nope."

"Have you never liked anyone?" As if he thought this answer was too strange, he couldn't help but add.

"Nope."

At this moment, the number of items on the monitoring screen finally fluctuated visibly, and the person who answered the question quickly realized that he had lied on this question.

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

But what went wrong?

Although the subject began to struggle, the polygraph quickly turned the chapter, after all, who doesn't have some*?

The polygraph man continues to get back to business: "So, judging from the file, in the case of the candy thief, you happened to be on the hijacked bus, right?" ”

"Yes."

"Where are you going in the car?"

"Go on a trip."

"What a coincidence......"

The polygraph man said subconsciously, and at this moment, Lin Chen finally couldn't help but let go of the hand holding the teacup and said, "I'm sorry, please allow me to interrupt you." ”

"What's wrong?"

"I just listened to these questions from you, and I think the polygraph program you use should be the CQT Criterion Question Polygraph ......"

The polygraph turned to the first page of the text and looked at it, a little embarrassed.

"The criterion question polygraph is divided into four parts, neutral questions, criterion questions, related questions, and off-topic questions. For example, asking for names and ages are neutral questions, and the role of neutral questions is to establish a normal level of response, so try to ask the subject to answer a 'yes' question and a 'no' question during the questioning process, otherwise there will be a problem with the baseline setting.

The polygraph man closed the above sentence and listened helplessly.

"At the same time, when you ask questions about the case, try to write the pattern of the question into a pattern that allows the person to answer yes, the two questions you ask at the beginning are good, but then it becomes interrogation, interrogation and polygraph, after all, there is still a difference."

The polygraph opened his mouth and found himself speechless.

But Lin Chen's words were obviously not finished: "Actually, in a set of CQT polygraph questions, it is best to only involve one aspect of one question, and use the method of repeated questioning to determine whether the person being tested 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 ruthless.

The half-race young man standing behind the one-way glass almost burst out laughing, and it was a little cute that some people were annoyed and angry because they had answered the wrong questions.

"Mr. Lin, I kind of get it." The polygraph detector sighed, stood up, and took off the wires stuck to his body for Lin Chen, "If you lie sincerely, the instrument won't be able to detect it." ”

“……”

"It's just routine, you answer me a few more questions, and we'll call it a day."

"Excuse me."

"I read the file of the 'Candy Thief', as a temporary negotiator, you made a great contribution in the process of persuading Fang Aizi, but at the same time, you were also one of the last people to contact Yang Dianfeng, after that, Yang Dianfeng's police car was installed with a suction cup bomb, under the circumstances at that time, do you think Yang Dianfeng had time to give the information about his arrest to the criminals?"

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

"Because the criminals reacted quickly at that time, since it was not the criminals notified by Yang Dianfeng himself, can I make an inference that among all the people at the scene, someone directly transmitted the information to the criminals, so that the criminals could react quickly and kill people."

"I don't rule out this possibility, but in fact, I can also think that Yang Dianfeng himself is closely monitored by criminal organizations, and once he has a problem, he will be quickly eliminated."

"Please answer my question head-on and answer whether I can make this inference." The polygraph suddenly interrupted him and asked very sternly.

"Yes." Lin Chen was silent for a moment and replied.

"Continuing with the question, you are the most professional and systematic psychologist trained at the scene of the crime, so did you notice that someone was abnormal at that time, and out of all of them, who do you suspect is most likely to pass this information on to the criminals?"

Hearing this question, Lin Chen suddenly raised his head.

The two questions in this sentence are really full of the style of the inspectorate, full of conspiracy and traps, and it is even very likely that these questions themselves were drafted by Inspector Huang himself.

Originally, the purpose of the Inspectorate was to supervise whether the police officers exercised their powers correctly and appropriately in the process of handling cases, so since the Inspectorate suspected that someone had leaked secrets within the police, of course it had to start an investigation, but based on the inference of possibility, it was necessary to draw a definitive result, and it was really a bit damning to use such a naked question to encourage reporting and exposure.

"I do have professional training in psychology, but I am not a professional facial expression recognition expert, and even the most professional expression recognition expert needs to carefully observe and talk to find abnormal problems, you ask me, when I face Fang Aizi, when all the police officers are hidden in the reeds, have I found that there are people at the scene who have ghosts, then I can only answer you, I don't have the ability to find this problem."

―――

The audit process is always long and cumbersome.

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

The torturer was leaning against the stone pillar at the door, smoking a cigarette, and when he saw Lin Chen, he slowly straightened up: "Are you still smooth?" ”

Lin Chen shook his head and handed over the results he had just gotten.

Xing Conglian's face sank, he bit the cigarette butt, and quickly opened the report, his eyes fell on the last line of the report.

It clearly reads, "Audit Tong Guò".

The commander of the torture company couldn't help but press his hand on Lin Chen's head and rubbed it: "Hey, isn't this tongguò, why are you still shaking your head?" ”

"Didn't you ask me, Shun lì?"

"It's all tongguò, isn't it called shun lì?"

"I just think that Huang Ze will suddenly let go, and really let me go through the consultant to review, this matter is too strange."

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

He asked with a smile as he took a drag on his cigarette.
