When the first batch of exchange personnel returned home, they had to come to the second floor of the police office.

Yaoyao's affairs are well known, thirty-year-old people have a fourteen-year-old American daughter, "speeding second generation", too powerful, too long for Chinese, one by one with a playful smile on his face, and hundreds of more "admiration" in his eyes than before.

"Look at what to see, continue the meeting."

Zhang Xiangqiang held back a smile and drove a group of boys who were afraid that the world would not be chaotic into the conference room, and asked them to share what they saw and learned in the United States with those who did not go.

In the director's office there are a bunch of books and periodicals in English, such as the Forensic Review, the New Scotland Yard Criminal Investigation Yearbook, the Journal of the American Society of Forensic Examiners, the Newsletter of the American Social Crime Research Office, the Forensic Papers published by CRC, and the Proceedings of the International Society of Forensic Studies...... It's all hard to buy in the market.

Director Han was very pleased, picked up a copy and flipped through it, and asked with interest: "Director Zhang, how do you feel about going out?" ”

"I have benefited a lot, I have seen a lot of advanced experience of others, and I have found that we have a lot of shortcomings."

"Tell me about it."

Zhang Xiang beckoned him to sit down, and said excitedly: "The day after I arrived at the murder team, there was a shooting case by the railway in Zhongcheng District, and one person died. It took only 3 minutes and 21 seconds from the time a citizen heard the gunfire to the police who arrived at the scene. ”

Han Jun groaned: "The speed of this police dispatch is not fast, under normal circumstances, it should be within 3 minutes, probably because the crime scene is relatively remote, and the proximity to the railway will drag on for so long." ”

"That's what they say, but it's fast enough for us."

Zhang Xiang waited for Jiang Huiru and Xia Moqing to sit down, and then said: "There are four things that impress me, one is that they have really achieved the informatization of police work, there are computers in the car, mobile terminals in their hands, and everyone is working online to collect information. Entering information and using information is a complete workflow, unlike us who treat online cases as an additional burden;

The second is that the most ordinary patrol officers are well-trained, and the first patrol officer who arrived at the current one is a black female policeman. She blocked two streets while calling the main station, and at the same time stopped a train to prevent the train from passing and destroying the scene, which seemed to be called AD in their words...... AD……”

"Standard Procedure."

Jiang Huiru knows that her business ability is not good, and she is very hardworking. I work very hard, as long as I mention the case and the criminal investigation, I habitually take out a pen and paper to make a record. Moreover, after the first batch of exchange personnel come back, they must share, summarize, and form materials to report.

When I heard this keyword, I couldn't help but ask: "Director, what does this ADAPT mean?" ”

Han Jun explained with a smile: "The abbreviation of English words such as arrest, liuzhi, assessment, and protection, if there is a suspect at the scene, arrest immediately, if not, keep important witnesses and suspects, and then evaluate the murder scene." Effective protection is then carried out according to the assessment. They are multi-functional, and everyone has received professional training, so many homicides are solved by patrol officers. ”

Recalling the experience that night, Zhang Xiang sighed: "The patrol officer is not good, she is very conscientious, but she has not been affirmed by her superiors. As soon as the homicide detective I was with arrived at the scene, he was very annoyed and asked you were the first police officer to arrive at the scene? She said, yes, sir. The agent asked her again, why did you block 11th Street? What are you thinking?

The relationship between superiors and subordinates was clear, and she respectfully said that the first police officer to arrive at the scene was responsible for arresting suspects and retaining eyewitnesses. Protection...... That's what the Director just said.

She thought that the suspect would not park his car on the side street, because it would be easy for people in the apartment over there to see, and Eleventh Avenue seemed to be a better choice, so she immediately decided to block it. ”

In reality, the American police handled the case, Xia Moqing heard about it for the first time, and asked: "What happened later?" ”

"The agents are very experienced. When I got off the bus and walked to her, I observed the scene, and it was very unceremonious to say that it was a wrong choice, there were no footprints on the side of the tracks, but two sets of footprints pointed to the iron ladder leading to 37th Street. ”

Zhang Xiang took a sip of water and continued: "The female patrol officer hurriedly said that she had blocked the 37th Street. The detective asked her why the train was stopped. Ask her what about Newark Airport, why not close the New York Highway, the New Jersey Highway and the Long Island Highway by the way? She said she could also close Interstate Seventy and block it all the way to St. Louis because it was entirely possible for the suspect to escape from those roads. ”

Director Han laughed and said nothing, Jiang Huiru was confused, and asked with a puzzled face: "People haven't done anything wrong, why criticize?" Are you there with the translator, and that murder squad agent is going to be prestigious? ”

"It's not."

Zhang Xiang shook his head and patiently explained: "There is a reason why the agent is angry, he received a bunch of phone calls from his head on the way, the director of the port authority, the office of the Secretary-General of the United Nations, the director of conferences...... The on-the-spot handling of the female patrol disrupted the proceedings of the meeting, the speech of a senator, and traffic throughout the West End. In his words, even Hurricane Eva didn't block Amtrak's Northeast Corridor so completely.

On the way back, he told me that crime scene work should be balanced, and that it would be nice if the whole city was locked down after every homicide and all three million people were left in custody for questioning, but they couldn't do that. In other words, they simply can't do it on a large scale like we do. ”

"So how do they solve the case?"

"Rely on on-site investigation, rely on police information technology, rely on monitoring, rely on informants. The work is equally fine, more detailed than ours. For example, when surveying a site, two technicians are considered to be the most efficient, believing that one person may miss something, and more than three people will miss something.

The agent is not a technician, but he understands technology, and lets the sampler collect fingerprints, let the photographer take pictures and videos, and he does it by himself. Finally, a screw was found, and the screw was used to determine the approximate location of the victim or suspect from which he came, and then he went with his partner to visit and question, and at the same time mobilized an informant to lock down the suspect, and the next afternoon he was caught. ”

Xia Moqing asked suspiciously: "A screw?" ”

"Really, just a screw, and people's analytical skills are like Sherlock Holmes."

He took out the screws in his mobile phone and was about to explain, Director Han took the mobile phone and looked at it, and suddenly smiled: "The detective is very familiar with that area, and the rock bed in Zhongcheng District is close to the surface. This means that it is mostly an aquifer. From Thirty-Fourth Street to Harlem, the soil was so moisture that it didn't take a few days for the nails to rust.

If the screw is buried in the soil, it will rust completely. There won't be just the top. So it may have been inadvertently brought to the scene by a suspect from somewhere. And with the sand on it, it's unlikely that you'll find a pile of white sand on the Central Railway, because the soil is made up of loam, silt, granite, gravel, and soft soil. ”

Zhang Xiang was stunned for a while before asking, "Director, how do you know?" It's almost exactly the same as his analysis. ”

Director Han smiled embarrassedly: "There's nothing strange about this. The education received is different, the country is cramming, the United States is heuristic, the teacher will assign students to do some social research on geography and geology, sometimes one person does it, sometimes several students have to cooperate, which is equivalent to homework.

When I was in middle school, my teacher assigned this homework, but because I didn't have time to do it seriously, I wrote it blindly, and the teacher finally debunked it. It's embarrassing, it's impressive, and it's not hard to see. So before I went to Dongshan to assist in the case, I told everyone that a good agent cannot live in a vacuum, and the more you know about the surrounding environment, the more conducive it is to solving the case. ”

"Director, you are a god!"

Jiang Huiru complimented her sincerely, and then asked with a smile: "Speaking of education, how does Yaoyao feel about the official class yesterday." Are you used to it? ”

When it came to her baby daughter, Director Han showed a knowing smile: "It will definitely not be too smooth at first, and after the first math class, she thinks that Chinese students are too powerful." Don't use a calculator to solve such a difficult problem, think that all Chinese students are mathematicians; After taking physics class, I thought that the atomic bomb was built by China first, and I thought that everyone in the class was little Einstein.

The teacher ran away from the teacher in English class, and then walked up to the podium to be a teacher, English is her mother tongue. The whole school teacher who has her said well and taught well. I went to apologize to people early in the morning, said good things to people, and bribed a little before I came back, and stuffed a supermarket shopping card of 1,000 yuan for each of the teachers. ”

The three of them almost laughed, Xia Moqing stroked his sore chest with his hand, and joked out of breath: "Director, why don't I send my son to your house and let Yaoyao teach him English." ”

"She can also gain a foothold in the class in English, and she can't keep up with the other homework at all, so I just asked for a set of textbooks in the school, and I learned it first, and then taught her."

"It's not easy to be a parent, you have to go to junior high school again, and I'm going back to elementary school now. Now those teachers, I really can't say that the homework assigned is too difficult, and sometimes my husband and I can't figure it out for a long time, so we can only look it up on the Internet. ”

"yes, it's a child's death. However, my Yaoyao is too playful, and she is from the United States, so it is not a bad thing to put some pressure on her and let her know the gap with her classmates. ”

Jiang Huiru asked curiously: "Are you used to life?" ”

Director Han sighed lightly, shook his head and said with a wry smile: "She likes to eat Chinese food and can use chopsticks." She didn't even taste the desserts I baked and the American dishes I learned to make. ”

Xia Moqing snorted and said, "This is a good thing, isn't it a family that doesn't enter a family." ”

"Shiro is worried."

Director Han nodded slightly, and said: "She is very strong, I found that my classmates are very powerful, and I want to be equally powerful, and she is interested in learning, so she took the initiative to ask Zhang Lin to make up for her for an hour and a half after school yesterday afternoon." The only thing I am not used to is the toilet, complaining that the school toilet is too dirty. ”

Zhang Xiang had just returned from the United States and said with deep contemplation: "The domestic toilets are not as clean as the American toilets." ”

Jiang Huiru asked worriedly: "Director, she has to stay in school for so long a day, and she is a girl, how can this problem be solved?" ”

Director Han smiled casually: "Slowly get used to it, and Zhang Lin prepared a few masks for her to wear when she went to the toilet." ”
