Chapter 166: Practical Application

Ningtai County Bureau seemed particularly quiet.

At six o'clock in the afternoon, a large number of men and women wearing shiny trousers merged into the traffic after get off work.

There were no pickpockets in the bus, and they just watched the men and women in trousers and people wearing shorts quietly heading home.

Jiang Yuan rode a boring scooter, like a middle-aged uncle, rushing out of the parking lot and merging into the crowd, like an ordinary social medium-to-large livestock, heading home.

Today was another day when only a small backlog case was solved.

There was a sense of satisfaction, but not particularly satisfaction.

It was like eating a hot pot and a white soup pot, and only eating 80% full.

It was delicious, but I always felt that something was missing.

In a nutshell, it was just a big appetite, and this kind of case that sentenced people to two or three years always felt wrong.

Other relevant departments probably had similar feelings. For example, the police officers in the case handling center kept delaying the interrogation of such criminals, and the prosecutors also looked like they were doing their job.

Police officers at all levels no longer showed their enthusiasm in solving the backlog of murder cases, and sometimes they even dragged their feet and couldn't find anyone.

I can only say that it's a good thing that Jiang Yuan is a technician, otherwise, he would be annoyed by the trivial things in handling cases.

For several days in a row, the Criminal Police Brigade was in this unhurried posture.

Like a buffalo, when there is no work to do, it buries its body in the water, gurgling and exhaling, and just exhaling.

Jiang Yuan wanted to solve another backlog of murder cases, but he found two fingerprints and compared them for three days without matching them, which was also helpless.

In the peaceful atmosphere, Jiang Yuan seemed to have returned to the state when he first joined the Criminal Police Brigade, looking at watering the green ivy.

The police station seemed to have seen everyone's leisure and quickly pulled out several scheduled projects.

The first one to bear the brunt was fingerprint skills training.

Several counties and districts sent a trace inspector to arrive at the Qinghe Municipal Bureau on time. When they arrived at the dormitory, they were thrown into the conference room, each with a book, and began to study.

In the disciplined forces, as long as the leaders want, they can make the training very serious.

Ningtai County sent two people, one Jiang Yuan and one Wang Zhong.

Wang Zhong is a trace inspector who has participated in training all year round. Although his growth is slow and limited, it is also by relying on this method that Comrade Wang Zhong can barely maintain the level of 9, thus ensuring the normalization of fingerprint work in Ningtai County.

Trace inspectors of Yan Ge's generation rarely come out for training. Employees over 35 years old are in the mature period of an employee, which means that from this point in time, in addition to a salary increase, his skills and level are basically fixed.

Various training activities do not like this kind of disobedient old helper. Everyone hit it off and sent and harvested young people.

Jiang Yuan participated in the fingerprint skills training as a lecturer.

In fact, a large part of the reason for this fingerprint skills training was Jiang Yuan.

Training training, first of all, there must be a teacher to do the training.

In the past, Qinghe City invited fingerprint experts from outside to give lectures for similar training. Although the cost was not high, it was not easy to hire people.

These days, information transparency is getting higher and higher, and the pyramid shape of experts is becoming more and more obvious.

Low-level experts are unwilling to come out and embarrass themselves, and there are too many high-level experts.

Qinghe City is just a prefecture-level city in Shannan Province. It is not well-known in the ranking of cities, and the funds are not sufficient. Moreover, the Municipal Bureau does not only train fingerprints.

Over the past few years, Qinghe City has basically maintained only the minimum fingerprint training. The content of the training is also mainly based on fingerprint collection.

The basis of fingerprint comparison is fingerprint collection. Each county and each township collects a certain amount of fingerprints every year. It seems that there is no direct use, but in fact it indirectly stabilizes social security.

However, the low quality of fingerprint collection has always been a problem that has troubled everyone.

The training of the Qinghe Municipal Bureau is mainly focused on this aspect.

The training outline that Jiang Yuan got is also the same.

Sitting in the office of the Municipal Bureau of Trace Inspection, Jiang Yuan looked at the training outline and was a little silent.

How to improve the quality of fingerprint collection... This topic is actually more about management than technology.

"The textbook is old, and we haven't had time to change it. You don't have to follow the textbook." Cao Keyang, a trace inspector of Qinghe Municipal Bureau, said cautiously.

During the fingerprint battle, 10 unsolved homicide cases were solved in one fell swoop. This kind of record is famous no matter where it is placed.

Other criminal police can comfort themselves because of their different police types, but Cao Keyang, who is also a trace inspector, does not have so many channels to release emotions.

Although Jiang Yuan is young and comes from the county below, to Cao Keyang, Jiang Yuan is more important than other experts from the province.

Because he is a local policeman, with the current mobility of regular policemen, Jiang Yuan may stay in Ningtai or Qinghe City for the rest of his life.

There will be many opportunities to deal with him in the future.

Jiang Yuan hadn't thought of that much yet. Seeing Cao Keyang's good attitude, he flipped through the textbook and asked tentatively, "Then why don't we follow the textbook and talk about whatever I want?"

"The main scope of our training is still fingerprints. Those who come are all trace inspections from all over the country." Cao Keyang quickly defined the scope, fearing that Jiang Yuan would deviate too much.

Jiang Yuan was even more confused: "Then...are there other textbooks?"

Cao Keyang hesitated for two seconds: "The ready-made teaching materials are these on the market... Why don't you talk about them? You can talk about anything you want."

Speaking of this, Cao Keyang actually looked forward to it.

To be honest, he now really wants to listen to the fingerprint second-class merit trace examination... or the fingerprint lecture of the forensic doctor. Just talking about it casually may better reflect their ideas and thoughts.

"Just talk about it casually." Jiang Yuan was not afraid of the stage. After thinking about it, he said: "Then I will talk about fingerprint practice?"

The skills he obtained are actually practical, and this aspect is also the most familiar thing during his work.

"Practical is good." Cao Keyang nodded repeatedly and said: "Then I will post it on the official account according to this? Our Qinghe Municipal Bureau's official account said that it would give us a position and we can post a manuscript."

Jiang Yuan said "OK".

Cao Keyang confirmed: "What kind of practical do you want to talk about, such as current cases, backlogs, or what kind of crime scene..."

"Backlogs. It's not easy to find current cases on the scene." Jiang Yuan answered after thinking.

Cao Keyang responded again and sent a message quickly.

At this time, he was far from realizing the specific meaning of what Jiang Yuan had just said.

The next day.

Jiang Yuan came to the small lecture hall of the Municipal Bureau.

In China, the ministries and provincial departments do not handle cases, which is equivalent to pure agencies.

There are two types of municipal bureaus. One is to handle cases. This is a trend in recent years and meets the requirements of the sinking of police force. But there are still a considerable number of municipal bureaus that still do not handle specific cases.

For example, Qinghe Municipal Bureau.

As for the specific cases that occurred in the jurisdiction of Qinghe City, they will be handed over to the district and county bureaus.

If you are not pragmatic, you will naturally be idealistic.

Bureaus like Qinghe Municipal Bureau are more active in activities such as training.

The bureau has also built a special small lecture hall, like a small tiered classroom, with corresponding teaching facilities, and can also hold meetings and parties.

Jiang Yuan was led to the lecture seat and sat down. Cao Keyang came forward and asked, "Do you want to play the PPT?"

"Just project the computer screen." Jiang Yuan brought his own laptop and put it on the table.

This laptop is also an old-fashioned high-performance version equipped by the Criminal Police Brigade.

Cao Keyang helped to adjust the line and made way for him.

There were already more than 40 people sitting in the small lecture hall. Some were from the county bureau, some from the district bureau, and some from the city bureau's own trace inspection. In addition, some places also sent ordinary police officers to receive training.

In fact, the training of ordinary police officers is itself the highlight of the city bureau's training. For example, some police officers in police stations actually undertake a lot of fingerprint collection work. And before they took this position, they may only know how to use tape to stick fingerprints.

Jiang Yuan also noticed that there were a few more people, and couldn't help but whispered: "Are there any non-professional police officers?"

Cao Keyang understood what he meant and said: "It's okay, there are several classes. You are good at teaching practical cases, and you can show other police officers what practical trace detection looks like."

Cao Keyang imagined that Jiang Yuan would bring out his own practical cases to explain.

He was very interested because of this.

There is no one who does fingerprints who doesn't want to match a homicide case one day.

Even Wang Zhong, a 9-level trace detector, who scans the database all day long, thinks about this. He just knows that his strength is not enough, so he uses the method of scanning the database.

For people like Jiang Yuan, who actually match a homicide case, the fingerprints dug out from deep in the database are almost a professional dream for trace detectors.

If there is a dream for this profession, it can only be this.

Jiang Yuan was already sitting on the podium, and it was not easy to adjust the lecture plan. After Cao Keyang left, he cleared his throat and said, "Then let's start."

Everyone began to applaud obediently.

Jiang Yuan smiled, then looked at the microphone and the screen and said, "Because this is my first time giving a lecture, so today I want to start with a practical exercise. While doing it, let's talk about the problems we encounter."

Jiang Yuan opened the software and the intranet and said, "I think fingerprints are actually like doing questions, like doing math problems. Well, let's find a more typical question to try..."

As he spoke, he selected a fingerprint.

The trace inspectors who were familiar with fingerprint work also understood a little at this time. Could it be that this person wanted to compare fingerprints on the spot?

Cao Keyang was even more confused. Didn't we say "practical"?

The difference between "practical" and "actual combat" is one word, and the meaning is much different.

Besides, if you compare fingerprints on the spot, what if you can't compare?

What if the fingerprint is not in the library, then what?

Have you ever thought about this question?

Just when Cao Keyang was shouting in his heart, Jiang Yuan slowly said:

"Let me talk about the fingerprint selection skills first, for example, why I chose this fingerprint. First of all, it is a slightly difficult fingerprint. If it is a fingerprint with no difficulty at all, then don't consider it. There must be no corresponding fingerprint in the library..."

"Secondly, the difficulty of the fingerprint is close to your own limit, which is also a better choice. This is also conducive to your own improvement. And it can match the fingerprint with the greatest possibility."

Jiang Yuan is not talking nonsense. From the time he acquired the fingerprint skill to now, he has clearly felt the improvement of his proficiency. Although it is much slower than what the system gives, if he persists for a few years, he will surely gain something.

Among them, Jiang Yuan feels that the most useful thing is to do fingerprints close to the limit.

The policemen in the small lecture hall had calm expressions. After all, it was just words, which did not cause much stimulation.

At this time, Jiang Yuan began to mark the characteristic points.

"Let's try it once." Jiang Yuan casually marked a dozen characteristic points, which took only one or two minutes.

In the lecture hall, the whispering sounds that were originally there had long disappeared.
