"Don't yy me, do something practical!" Zhuang Zheng approached the desk and asked seriously, "Is there any progress?" ”

"Why should I tell you?" Ding Xiaoqing seized the opportunity to fight back.

"First, I am also one of the parties, one of the victims, and they may retaliate against me; Second, it doesn't have a personal relationship with you; Third...... Tell me about it, and it might give you an unexpected clue. Zhuang Zheng winked at her.

Ding Xiaoqing frowned, the first two were impossible for her to say official business, but the third was still a little tempting. She wanted to get clues from him more than to prove that Zhuang was shooting.

"All five of them were arrested, and now they are all in the hospital. The clues that can be found from their mobile phones and other items have all been broken, and the people behind the scenes are very cunning, but according to your accounts, there must be a few accomplices in Shenjiang. Speaking of this, she was a little indignant: "Because some lawless people made their own decisions, they all had to be admitted to the hospital and underwent surgery last night, and now they can't be further interrogated!" ”

Zhuang Zheng smiled: "If that person hadn't shot, you wouldn't have been able to catch a single hair." ”

"You ——!"

"You're the captain, you don't need me to teach you how to do it. But I can remind you of two points! ”

"Say!" Ding Xiaoqing immediately listened calmly.

"First, you can't die if you are shot in the leg, don't treat them as VIPs, now they are weak and just interrogated. Don't concentrate all on one ward for the sake of convenience, that will give them a chance to collude and even escape. ”

Whether these are done or not, Ding Xiaoqing can think of it, and immediately said impatiently: "Say two!" ”

"Second, try to interrogate in the way of the prisoner's dilemma." Zhuang Zheng suggested.

"Prisoner's Dilemma?" Ding Xiaoqing frowned.

"This is a kind of game theory in economics, and the police can also use it to fool the suspect, but the confession is changed from leniency to resistance."

"Go on......" Ding Xiaoqing wanted to hear what clever things this guy could say.

The prisoner's dilemma actually involves psychology, surnames, etc., and the classic model is as follows:

The police arrested two suspects, A and B, but did not have sufficient evidence to convict them. The police then imprisoned the suspects separately, met with them separately, and offered them three identical options: if one pleads guilty and testifies to prosecuting the other ("betraying" the other), and the other remains silent, the person will be released immediately, and the silent person will be sentenced to 10 years in prison; If both remain silent ("cooperate") with each other, they will also be sentenced to one year's imprisonment; If both of them report each other ("betray" each other), they will also be sentenced to 8 years' imprisonment.

Everyone has a self-interested mentality and seeks the greatest self-interest, so they will choose the shortest personal sentence. However, due to the information asymmetry of isolation and incarceration, it is best to cooperate with each other without knowing the other party's choice. But putting aside factors such as self-interest and trust, in terms of the cost of the surname, the sentence for betraying the other party is always lower than silence-

The other party is silent, I am silent, the cost is 1 year; I betrayed, cost 0 years. Betrayal is a good deal!

The other party betrayed, I was silent, and it cost 10 years; I betrayed, cost 8 years. Betrayal is a good deal!

The two of them are facing the same situation, so both of them will come to the same conclusion - choose betrayal. Betrayal is the dominant strategy of the two. As a result, both participants in this game betrayed each other, and as a result, both served 8 years in prison. In terms of the overall interest, if both participants cooperate and remain silent, both will only be sentenced to one year in prison, which is a higher overall benefit, and the outcome is better than if the two betrayed each other and were sentenced to eight years in prison.

After listening to Zhuang Zheng's narration, Ding Xiaoqing roughly understood a little, and immediately overturned it: "Hmph! You are based on the assumption that both parties are rational and only pursue their own personal interests! If both of them are very trusting, very righteous, and do not betray their partners, it will not be effective! ”

"Draw inferences, comrade. There are five of you now, and you're still afraid of attacking? How can they trust that there is no intrigue, no unpleasantness? Zhuang Zheng reminded again: "Shooting can also be used, and spoils can also be used." You can say that in fact, their boss has already gotten the money, leaving them to give an explanation to the police, losing the pawn to protect the car, and losing the car to protect the commander. ”

"Okay, okay, I got it." Ding Xiaoqing also felt that there was a lot of room for control, and it had something in common with the usual interrogation, "What about your clues?" ”

"That's it."

"Finished?" Ding Xiaoqing glared at him, "Just give me a lesson like this?" Are you kidding me? ”

"It's better to teach a man to fish than to teach him to fish, I gave you a way to find clues." Zhuang Zheng smiled: "Is this a favor?" ”

"Count your head! Get out, get out! There are no clues, Ding Xiaoqing is too lazy to talk to him, she also wants to plan quickly, find a reliable plan to divide the five people, and let the colleagues in the hospital prevent them from communicating and colluding after waking up.

Just as Zhuang was getting up to go out, someone knocked on the door and opened it himself.

"Can I come in?"

Ding Xiaoqing frowned, the person who came was Yu Jun. "What's the matter? We're busy! ”

Everyone knows that Yu Jun came to her to chase her, and usually because of his old friend, he usually doesn't give him face, and he has borrowed Zhuang Zheng to refuse and hit him last time. But now that she's been busy all night, she's not in the mood to pay attention to him.

A man and a woman, a lonely man and a widow, said that they were very busy, which made the suitors embarrassed by the military situation! Zhuang just added heartily: "She said that the police station is very busy." ”

Ding Xiaoqing glared at him angrily, it's not that the police station is very busy, is it very busy with you.

Yu Jun, who was sad and embarrassed, got down the stairs and said busily: "I heard about last night's incident, and I just heard that Zhuang Zheng is also related, so I'll come over and take a look, if you need a guarantee or something, I can guarantee it." ”

As soon as these words came out, Zhuang Zheng and Ding Xiaoqing looked at each other, which tendon of this guy is broken? That's kind of ...... Want to confuse your rival?

Yu Jun was stunned by them, and said curtly: "Xiaozhuang and I ...... That one...... Don't fight, don't know each other. He's sure he can beat me and clean up a few thieves, but he shouldn't shoot on purpose. I ...... to him Uh, there is the trust of men! ”

“……”

After Ding Xiaoqing was speechless, he said angrily: "There is no evidence to make him a suspect, you don't need to vouch for anything, you can find him to engage in men's exchanges, go out, don't hinder me from doing things!" ”

“……”

Zhuang Zheng saw Yu Jun's enthusiastic eyes that were a little flattering, and this sincerity was not like a disguised attitude, which was a little hairy. Has this guy changed his tastes, or does he want to scare away his rival with the gesture of a friendly gay friend? A few of them came to the noodle shop that day to watch, could it be his comrade-in-arms, the one who came to buy noodles is gay, and wants him to introduce it?

"I have to go see Zhuo Wenxu......"

Yu Jun really followed Zhuang Zheng out and asked if there was anything he needed help with. That enthusiastic attitude made the other police officers stunned. Why would he be so righteous to Zhuang Zheng? The fire of gossip about the 36 plans for love, about the plot and the conspiracy, spread rapidly in the sub-bureau......

Seeing Zhuang Zheng coming, Zhuo Wenxu immediately greeted him, asked and communicated with his eyes, and looked strangely at Yu Jun, who was the same as his follower. Lu Ren accompanied Zhuo Yuanhang to come over, and when he saw Yu Jun standing beside Zhuang Zheng, he thought that he was coming to challenge again, so he hurriedly stepped forward and asked, "Less, we are all very busy, don't make trouble for us!" ”

Yu Jun was a little sweaty, "Lu Bureau, I'm just coming to see Xiaozhuang and reminiscing about the past, and I won't add to the chaos." ”

General Lu Ren was suspicious, and also introduced him to Zhuo Yuanhang. He was not too surprised by the captain of the armed police anti-riot team, he even knew the leader of the Shenjiang City Armed Police Detachment. But Yu Jun's attitude towards Zhuang Zheng made him feel intriguing! The whole of the Southern District Bureau, including the head of the sub-bureau, knows Zhuang Zheng, and the captain of the armed police riot police is still so enthusiastic, could this be an ordinary student? I can't figure out that this Zhuang Zheng's father is the head of the armed police force!

He looked at Zhuang Zheng with more respect in his eyes......
