The fingerprint battle is a case-solving mechanism that the public security system has been carrying out for many years, aiming at the detection of backlogs.

The exact earliest start time is no longer known, but over the years, the tradition has continued.

From ministries to provincial departments to municipal bureaus, fingerprint battles are organized more than once a year. Further down the level, there is no going to the district and county public security bureau, criminal police brigade or technical appraisal center.

On the one hand, the lower the level, the fewer capable people, and if you engage in fingerprint battles, there will be two or three big cats and kittens, which are no different from the work you usually do, so you will naturally not fight.

On the other hand, the grassroots level has limited energy, and normal cases cannot be solved, so there will naturally be less attention to the backlog of cases.

The Haizhou Municipal Public Security Bureau conducts a fingerprint battle every year, usually in early February, on the eve of the Spring Festival.

The main consideration for choosing this time point is to select people to participate in the annual fingerprint battle organized by the provincial government in March.

Of course, in the eyes of Yang Sen and Lao Bai, the fingerprint battle of the Haizhou City Public Security Bureau is not very interesting.

The overall situation, who can do fingerprints, both know each other. In the district and county criminal police brigades below, each team can produce one person.

The technical appraisal center can produce two people. In previous years, Liu Guodong participated in the criminal investigation detachment. Generally speaking, the fingerprint battle of the Haizhou City Criminal Investigation Detachment was attended by more than a dozen people.

There is no need to compete, everyone knows that Liu Guodong's technical level is the highest. Otherwise, he would not be able to be the current investigation leader of the criminal investigation detachment.

This year, however, the situation has clearly changed. Liu Guodong picked up the enamel jar and walked to Lu Chuan's side: "Xiao Lu, this year, you will represent our criminal investigation detachment to participate in the fingerprint battle of the city bureau. ”

"I've already greeted Team Qin." Lu Chuan nodded, he had no opinion on this, but was quite curious.

"Master, what's going on with the fingerprint battle?" When he was in college, Lu Chuan had heard about the fingerprint battle, but what was going on, Lu Chuan had never participated in it, so he didn't know.

didn't wait for Liu Guodong to speak, Lao Bai accosted: "Actually, there is nothing mysterious, it is to gather everyone in one conference room." ”

"One person and one computer, get a fingerprint database of backlogs, and everyone will compare them together." Yang Sen nodded: "Generally, you can still hang a banner, and the city bureau will also hold a simple ceremony." ”

"Go ahead, it's good, eat and drink well, and sleep well." Liu Guodong took out a piece of Huazi from the foot of the table, sniffed it, and lit it: "The fingerprint battle held by our city bureau in previous years has greater symbolic significance than practical significance. ”

"The backlog of cases in the bureau are all left by our detachment and various criminal police brigades, and we have studied them before the battle."

"You can't do it in peacetime, but you can't do it in battle." Lu Chuan was puzzled: "That'...... There will be no results in the fingerprint battle? ”

"Not really, the city bureau will also put some simple fingerprints, anyway, it won't make the battle fruitless." Lao Bai walked over and patted Lu Chuan on the shoulder: "Don't worry, the old men over there in the city bureau can't solve the case, they do this kind of thing one by one." ”…… February 1, fine, minus 24 degrees.

Today is the coldest day since the beginning of winter, and Lu Chuan rushed to the Haizhou City Public Security Bureau early in the morning to report.

The fingerprint battle organized by the city bureau will start today. As Janssen said, before the fingerprint battle began, the bureau conducted a simple ceremony.

Deputy Director Wang Kai cordially expressed his condolences to everyone.

"I hope that in the next week, you will have the courage to break through yourself and create more brilliance!" The ceremony was simple, but when the deputy director appeared, everyone's energy was still very high.

As a grassroots technical criminal policeman, it is not easy to see the side of the director and deputy director. Some people, even after working for decades, have never seen what the director looks like.

Of course, after the ceremony, Wang Kai left, and everyone returned to their original faces. Everyone is from the Haizhou Public Security Bureau, and most of them work in technical positions, even if there are a few front-line criminal police cameos, everyone is familiar with them.

"Lao Zhang, it's been a long time, the last time we met was in July, right?"

"Brother Wang, let's take a walk and smoke one?"

"Brother Li, thank you for the case of the theft on the friendly road last time, if it weren't for your help, that gang of bastards would have run away again......" Most of the people looked up and didn't look down, and they were more familiar with each other.

Lu Chuan was the only one, and no one around him came to say hello. However, it doesn't mean that everyone doesn't know where Lu Chuan came from.

The Haizhou City Criminal Investigation Detachment is the superior of the criminal police brigades of various districts and counties, and Lu Chuan came to participate in the fingerprint battle on behalf of the criminal investigation detachment this time, obviously in place of Liu Guodong.

You must know that in the past, when Liu Guodong was there, everyone had to revolve around. After all, everything that cannot be done at the grassroots level must be handled by the criminal investigation detachment.

But Lu Chuan is young, and everyone is not familiar with it. Lu Chuan was also happy that no one bothered him, and after the ceremony was completed, it meant that the fingerprint battle would begin.

In the conference room, there are two rows of computers, each with a person's name in front of it. Lu Chuan walked to the first computer on the right-hand side and turned it on.

The fingerprint battle lasted for a week, and the food and accommodation were all in the hotel given by the city bureau. Everyone, the phone is handed in, and the work of the original unit is not cared for, just compare fingerprints here with peace of mind.

This creates an atmosphere that you can't create in your own unit. For seven days, I looked at the fingerprints, and there were some fingerprints that were not matched before, and maybe in this atmosphere, they were compared.

It is still the fingerprint comparison system that Lu Chuan is familiar with. But in addition to that, there is a battle fingerprint library.

Curry has accumulated all these years, all the Haizhou City Public Security Bureau, with fingerprint clues. The case that can enter the fingerprint battle is basically a case that can directly lock the suspect through fingerprints.

Therefore, as long as the criminal police in charge of comparison can successfully compare in the system, it means that the case has been solved.

All that remains is to follow the map and arrest people directly. As for whether or not you can catch someone, it has nothing to do with the fingerprint battle.

Lu Chuan: They are responsible for technical work, and physical work is not under their control. That is, the kung fu of two cigarettes, and everyone who was still greeting just now came back again.

Of course, not everyone ran out to smoke. No matter where you are, there are always people who are alone.

Lu Chuan just glanced at it, and there were three or five people, after the ceremony, just like himself, sitting in front of the computer with his own name, turning on the computer, and running fingerprints.

The room fell silent. Although many people know each other, they are not in a grassroots unit after all, and after a while, after chatting about familiar topics, they naturally want to start working.

After all, the fingerprint battle is not a tea party, and the colleagues present also have a competitive relationship. Although the scale of the fingerprint battle organized by the Haizhou Municipal Public Security Bureau is not large, and there are not many cases that can be solved each time, there will still be results in the end.

And most of these results, judging from past experience, are cases that occurred during the battle from the beginning of last year's battle to the present.

Generally speaking, there can be thirty or forty up. This is the case that all the combatants are focusing on, because in the previous cases, these criminal policemen who have participated in fingerprint battles all year round have chewed on it for I don't know how many times.

Even, many of these cases themselves have not been solved, so they have become backlogged cases. So, time is of the essence.

The probability of a new case is greater than that of a fingerprint, and whoever takes the lead will be able to pick the fruit.

Lu Chuan is also looking forward to this fingerprint battle.
