crime profiler in the dark

Bai Haolin continued to play.

"..., you killed your teacher!!" the prosecutor yelled and asked, "You stabbed him eleven times. This is a premeditated murder case!!"

"No!! I didn't—!!!" he yelled.

Here, Bai Haolin pressed the pause button again, made his facial expression bigger, and pointed at his wrinkled nose:

"It's a typical expression of shame and anger. When you see this expression during interrogation, you know you have hit the nail on the head."

After analyzing the video data, Bai Haolin faced the police officer and said half-jokingly and half-seriously:

"Fortunately, the law of heaven is clear, and the case was finally closed with intentional homicide." He said, scanning all the police officers present, observing their actions and expressions at this time.

"But this is a convicted case. How should we judge during interrogation? For example, when we question a suspect, how do we know if he is lying?" A police officer asked.

"Excuse me, what did you do last night?" Bai Haolin didn't answer his question, but asked instead.

"Last night I worked overtime until 07:30. After get off work, I went to eat a bowl of noodles, then went to the supermarket to buy some things, went home and helped the children with their homework, read a book for a while, and went to bed around twelve o'clock." The policeman said. spoke fluently.

"I didn't hear clearly, please say it again." Bai Haolin smiled.

The police officer had a "duped" expression on his face.

"This is the disadvantage of fabricating lies," Bai Haolin explained, "Repeated questioning is one of the skills to see through lies, but criminal cases now tend to be more and more high-IQ crimes, premeditated criminals are very likely I have already practiced it repeatedly, so the observation of body movements, behaviors and expressions has become an important basis. Because time is limited, I will not explain too much for the time being. Interested colleagues can discuss with me alone. Finally, I would like to use the famous The psychologist Sigmund Freud concluded: "No one can keep a secret, even if the lips are closed, the fingertips can speak, and every pore reveals the secret." He finished speaking to everyone A bow was taken to thank them for their time.

The police officers in the first division gave Bai Haolin a warm applause.

After returning to the office, Bai Haolin deleted all the names of the police officers he had listed on the form.

The cases he taught have no additional significance, the only thing I want to observe is the reaction of the "violent policeman" when he sees him - Bai Haolin has been defeated by him twice, and his knowledge of criminal psychology is currently at the limit. If it didn't play any role in deciphering the identity of the "voluntary policeman", the proud "volunteer policeman" must be quite disdainful of this, but now Bai Haolin, who is the defeated underling, suddenly appeared in front of him in an authoritative capacity. A "vigilante" accustomed to cynicism would certainly not be overly enthusiastic or interested in what he had to say.

It's a pity that Bai Haolin didn't notice that any of the police officers in the first place looked different, so let's exclude them all for the time being.
