Chapter 342: Attack

Guqi Municipal Bureau.

The sunset in the evening reflected the red clouds, making the thick clouds transparent.

With Gao Changjiang's order, the originally quiet courtyard of the municipal bureau instantly became boiling.

Hundreds of police officers, not knowing where they popped out from, stood out from upstairs, downstairs, the basement, and the corners and gaps, each fully equipped and lined up in the courtyard.

Gao Changjiang put on training clothes, put on a bulletproof vest, slung a holster around his waist, and looked down with black fire all over his body.

"Four children under the age of 5, supervised by the ministry, the earnest concern and urging of leaders at all levels, how important the case is, I don't need to remind you too much. Now I allocate tasks. Units and individuals who receive tasks, don't fight for credit, don't retreat, don't fear difficulty, don't fear sacrifice, must complete the task with all efforts. Even if knives fall from the sky, you must complete it by carrying the corpses of your comrades!"

Gao Changjiang held a megaphone in his hand, his voice was loud and clear, and the order carried a kind of brute force.

Jiang Yuan looked at both sides in surprise, and then asked Dong Bing beside him: "Is your Director Gao usually like this?"

"Small cases definitely won't be. For major cases, Director Gao is like this." Dong Bing answered in a low voice.

Jiang Yuan let out an "Oh." In the current police force, slogans like not fearing sacrifice are shouted less and less.

This Director Gao Changjiang, when doing case analysis, is like an ordinary police team leader, even with a little bit of weakness. I didn't expect that when preparing for battle, he would be high-spirited and his courage would double.

Wu Xia, using the experience equivalent to boarding in a relative's house for 35 years, saw through Jiang Yuan's thoughts, laughed lightly, and said: "Director Gao was from the border defense before, and only transferred to the local area later."

"No wonder." Jiang Yuan nodded in relief, and then looked at the criminal police of the municipal bureau, who set off one team after another as if heading to the battlefield.

The latest news also kept pouring in like flowing water.

"The mobile phone of the criminal suspect has been determined, and the number has been sent over now."

"The WeChat of several people has all been determined."

"Their next stop is very likely to drive out of the provincial border, and then get off the highway at Xinming Township, Xingfeng Province. Xinming Township has their den."

"The total number of this group might be more than 30 people. The specific quantity and the head of the group are not yet determined..."

A criminal group is like an isolated island. Before there are coordinates and the location is unknown, finding the isolated island is a long exploration that requires luck. But after finding the isolated island, and even landing on the isolated island, the information suddenly becomes cheap and rich.

The next problem becomes how to successfully capture the isolated island, and harvest the fruits of victory as much as possible. Or, bury these dirty fruits.

Jiang Yuan and several experts listened to the reported information and turned to the leisurely stage of checking data.

Until the number of 30 people in the group was reported, it slightly attracted a little attention.

"This can be considered a medium-sized group, very likely to be itinerant nationwide. The work of searching for old cases before can be continued." Zhang Xian arranged with experience.

Jiang Yuan nodded. Without needing to say much, Mu Zhiyang and others moved by themselves.

The criminal police from Guqi City beside them also followed to search and get busy.

Jiang Yuan looked at the case himself, and also couldn't calm down for a long time.

The abduction of women and children was a high-incidence period in the 90s. The ministry continuously organized 4 national-level anti-abduction campaigns, with significant results. By the year 2000, the cases of abduction of women and children had dropped in a straight line, to about 2000 cases per year. But starting from 07, such cases were continuously high-incidence again.

Moreover, the current various abduction groups have a trend of expansion, and the chains formed are getting longer and longer. Multiple resales are already a common phenomenon, and criminal members have also begun to adopt single-line contact, and the degree of professionalism has obviously strengthened.

In Jiang Yuan's view, greed and low punishment are complementary.

Members of abduction groups are generally low-educated and low-income, and are mainly women.

After these people are criminally punished, re-employment is basically impossible. Nowadays, doing cleaning and being a nanny in the city requires a no-criminal-record certificate. These people obviously also find it difficult to produce a hard technical level to let units pinch their noses and accept them.

The rest is nothing more than farming or being an individual household. The latter is equivalent to starting a business, and it is not that easy.

Finally, these members of the abduction group who have received re-education in prison will find that it is still faster and more comfortable to abduct women and children to make money. Especially abducting children, it almost doesn't require any capital. It's just a few train tickets and a few days of accommodation expenses to complete a transaction and harvest tens of thousands of yuan.

Not only that, these members of the abduction group who have received the iron fist of dictatorship, once they decide to continue their criminal career, they transform into backbone members of the criminal group. As long as there are a few such group members, they can support a large group of more than a dozen or even dozens of people.

The anti-abduction craze in 2000 ended, and the abduction groups reignited in 07. It is hard to say how many group backbones are hidden in it.

"I suggest we can determine the appearance of these group members in advance. Can we find their photos?" Jiang Yuan looked at Director Wang who did image tracking.

"As long as there is video, finding people is a simple thing." Director Wang smiled. His specialty is tracking the activity trajectory of suspects or anyone through images, equivalent to an electronic dog.

This kind of work, placed in film and television works, seems to be a matter of course. When it is played on the big screen, the camera follows wherever the suspect goes. In reality, this is naturally impossible. Cameras always have blind spots, and there are broken cameras, and places without cameras installed.

Most importantly, the networking of cameras itself is a big project. Cameras under different jurisdictions are also rarely merged into one system. This is not a permission problem, but a technical problem.

In short, even tracking vehicles requires special personnel to intervene to follow and track. Refining to people has more difficulty.

"I'll help you later." Jiang Yuan gave Director Wang a sentence, and then continued to look at the social media information gathered by others.

Director Wang let out an "En" and didn't take it to heart.

Jiang Yuan might indeed be outstanding in trace examination, surprisingly outstanding, but in terms of images, what role can trace examination play? If he really wanted an "observer" with staring eyes, he would rather have Dong Bing.

Jiang Yuan temporarily released Director Wang and searched the chat content of the criminal suspects himself.

After determining the mobile phone number or account, the relevant content can be directly retrieved from the backup server. For the police, quickly searching for useful content is the main work. Common ones, such as determining the group of criminals, if there is group chat buying takeout, you can determine the suspect's residence through the takeout address, or...

A lot of information was extracted. Useful ones were sent to the front line, and those that needed further investigation had other front-line personnel available for dispatch.

The benefit of a ministry-supervised case is that resources and manpower will not be lacking. Theoretically, with these two things, 99% of cases can be solved. It is just a matter of difficulty, time, and degree.

Soon, Director Wang pulled out the images of the first batch of personnel.

Jiang Yuan heard the movement and took the initiative to go over to look. Sure enough, he saw Director Wang's two assistants working hard to enhance the images.

The surveillance screen is greatly affected by itself and the environment. On one hand, it is exposed to the outside, and wind, frost, rain, snow, or haze will affect the clarity of the image.

Another point is that the clarity of the surveillance screen itself is also limited. No metaphor is needed. The difference in image quality between 4k resources and 1080p resources or 240 resources is obvious to all. And surveillance equipment is installed successively. Some places still use 10-year-old surveillance, and the investment in different places is also different, so it cannot be generalized.

Apart from this, distance is also a decisive factor. With the same image quality, shooting a human body within 1 meter and a human body 100 meters away is definitely different.

All of the above can be partially or completely solved by image enhancement technology.

Director Wang's

As an expert in image tracking, he obviously values related problems very much. The younger brother he brought worked hard, constantly pulling out various boxes and command lines. The main one among them, at a glance, is a technical cow with LV2 or above.

In the field of image enhancement, a technician whose technical level can reach LV2 is already unusually expensive.

And the two technicians brought by Director Wang, whose image enhancement technology is above LV2, are obviously recruited from society. The other one, although looking like he came out of a police academy, also has LV1.5 image processing ability.

The cost of raising such two people is afraid to be more expensive than a police dog squadron.

Jiang Yuan patted the shoulder of the weaker technician on the right and said: "Make room."

He has been sold outside for a long time and is very used to dealing with people from other units. Sometimes, using language to describe his ability and technology, as well as the technical generation gap with the other party, the other party often thinks you are insulting him.

Instead, when he really started to operate, when the two sides' technical horizontal comparison was extremely regretful, normal people were often very calm.

The technician who was about one-third of the cost of a police dog squadron stood up blankly. He was not yet sure what Jiang Yuan wanted to do.

Jiang Yuan sat on his chair without giving way and started to operate with a bang. The technician of one-third of the dog squadron was stunned and looked at Director Wang for help.

Director Wang actually noticed this side and walked over slowly.

At this time, Jiang Yuan had already officially entered the process of image enhancement. He had just paid attention to observing the software of the one-third dog technician, slightly paid attention to the version, and easily entered the state.

By the time Director Wang came over, Jiang Yuan had already cleaned up the image of one frame.

This photo came from the rental company and was recorded by the surveillance in the parking lot. The quality of the image was average. It could distinguish the human face, but it was a bit difficult to see clearly and use it to recognize people.

And Jiang Yuan used the method of filling noise points, and even enlarged the human face.

"Is it okay?" Jiang Yuan asked for his opinion politely when he saw Director Wang coming over.

Director Wang is an expert in images and naturally knows the goods. He lay on the computer to look for a while and couldn't help but look at Jiang Yuan: "You also know image enhancement?"

"Consider it knowing a little," Jiang Yuan said, suddenly calling out the command line, and typed a row of functions—actually, there was no need for this at all, just to prove the strength of LV5 image enhancement.

The expressions and attitudes of Director Wang and his two assistants suddenly became particularly soft, like big strong men who had eaten LV5 dog food.

"Let's work hard and strive to fix the images of all the members of this group." Jiang Yuan was like a naval captain who had boarded a pirate island and started counting heads.

The only female police officer at the scene, Dong Bing, suddenly said in a voice that only Tang Jia could hear: "Ningtai Jiang Yuan, no wonder."

Tang Jia rolled her eyes and thought: Where is there a female police officer who uses such a coquettish voice? ===== CHAPTER 343 =====
