Chapter 978 Xu Jin

After Cui Qishan agreed to Liu Jinghui's plan, he did not report it to Tao Lu, but went directly to find the person in charge of the office. He then visited several criminal police brigades one by one and made several phone calls to colleagues in the public security detachment and other units.

The police have very clear distinctions between undercover agents, special agents and informants. Among them, undercover agents are the most noble and are rarely seen in ordinary cases. Special agents and informants are divided into those within the establishment and those outside the establishment. The use of the former is still quite strict, so no one likes to use them.

More often than not, after working as a police officer for a long time, they naturally get to know some marginal figures, exchange some phone numbers with them, and can ask them questions when necessary.

Some policemen even skip the step of exchanging phone numbers. They will deliberately select some stupider ones - there is no doubt that there are such people, and they are quite easy to find. Then, you just need to keep a close eye on them.

For example, a criminal police officer can select one or several stupid thieves, because they are stupid thieves with poor individual abilities and often like to work in teams. So, it takes a little time to understand the behavior habits of stupid thieves. For example, some thieves like to post blessing texts or pictures on their WeChat Moments before committing a crime, and some even use location tracking. Once they are found, they can be arrested without any escape.

When catching a thief, you can intentionally miss the stupid thief and let him escape "luckily". Then you can form a new team after you calm down.

For a particularly useful stupid thief, when you find it increasingly difficult to form a team with him, you can capture him once and throw him into the detention center to expand your network of contacts.

In short, different police officers have different working styles. Cui Qishan has worked in the Criminal Police Detachment for so many years. Even if he doesn’t know the specific details, he still has some understanding of the ability limits of his colleagues.

He just talks about what he can, without trying to cover everything.

He just needs to let out the wind, he doesn't need to create a hurricane.

At the same time, Jiang Yuan made a special trip to the Image Reconnaissance Detachment, but found nothing.

The bigger the city and the bigger the police station, the stronger the image detection force, the newer the equipment, and the more capable the personnel.

Jiang Yuan has Level 6 image detection - trajectory analysis. In theory, he can use the existing city surveillance video to track the suspect's location. However, precisely because Jiang Yuan has Level 6 of this skill, he has long been keenly aware that this trick is unlikely to be used this time.

At least it is useless in the early stages of pursuit.

Because the suspect did not have any particularly powerful anti-reconnaissance capabilities, nor did he have any powerful anti-reconnaissance conditions. The suspect jumped out of the police station wall at 2 a.m., unlocked a shared bicycle and fled. However, to keep an eye on a suspect riding a shared bicycle in the streets of Beijing in the early hours of the morning, you don’t need LV skills.

Even if the suspect walks around the streets and does some tricks, it is impossible for him to escape the investigation of the image detection in such an environment. Under such conditions, perhaps the AI ​​function of the software can lock the fugitive.

The Beijing Bureau is not short of talent, and it also has awesome image detection experts. Before Cui Qishan and Tao Zhi called Jiang Yuan, they would definitely have asked the most awesome image detection expert to look at it.

However, no matter how powerful the image detection expert is, he cannot stop the suspect from running straight into the wilderness.

Without surveillance, it's OK for a short section, but if it's too long, it's hard to judge the track. If it's a vehicle, there might still be hope, but if it's on foot, it will be even more difficult.

Jiang Yuan estimated that the suspect should have spent the night in a park that night.

The park has water and toilets, few surveillance cameras, and even fewer connected to the Internet. Of course, if the suspect is a little more ruthless, there are more ways to hide. In this way, you can stay up all night and change your route to escape during the morning rush hour the next day. There are still many ways to escape.

As the saying goes, rats have their own ways, snakes have their own paths. Jiang Yuan was not sure what the situation was like in Beijing, but in Qinghe City, local thieves who were familiar with the situation could find a bus pick-up point outside the bus station if they wanted to leave the city. This was one of the reasons why many bus stations emphasized that soliciting passengers outside the station was not allowed.

Ways like bypassing train stations are a common secret in small cities.

When Jiang Yuan came back from the Image Reconnaissance Detachment, he saw Cui Qishan and others already making relevant deployments.

Looking at the time, 12 hours have passed since the suspect escaped.

"If he keeps running, he might have already left the city." Cui Qishan felt a little uneasy.

"As long as you haven't gone abroad, it's all the same." Liu Jinghui waved his hand, gave Cui Qishan some emotional value, and then said to Jiang Yuan: "Jiang Yuan, have you been to the next province?"

Jiang Yuan shook his head: "I haven't been there."

"I haven't been here before." Liu Jinghui looked at Cui Qishan again.

Cui Qishan smiled bitterly: "I know some people. I offended them all."

"No problem." Liu Jinghui smiled and said, "Then continue to use Jiang Yuan's name? Or do you have someone else in your unit who can be used?"

"If it's Captain Jiang, the effect will be better." Cui Qishan quickly explained to Jiang Yuan: "Captain Jiang, the image detection database here is not related to the neighboring province. It would be best if you could give us a call."

"Will it be useful if I say hello?" Jiang Yuan knew what Cui Qishan meant, but was a little hesitant.

"Your phone call will definitely help. It will be very helpful!" Cui Qishan said with a smile: "Given your current reputation, everyone will definitely be willing to help you if they know it's your case."

Many databases in domestic systems or applications of high-tech are based on provinces. This has historical reasons and is also related to funding and management.

When we started the construction, we were preparing at the provincial level or even lower levels, and there were very few national databases.

The result is that the data of province A and province B are independent of each other. A few years ago, even the data of DNA and fingerprints were independent of each province. Suspects in important cases were also submitted to the Ministry and then distributed to each province.

Today, some provinces are interconnected, but many provinces are still not fully connected to the grid. As a result, if you go to the neighboring province and want to check data, you cannot find it directly and must find the corresponding department in the neighboring province to check.

Although the ministry can help with the written investigation, anyone who is not a foreign guest will know that. No, if they are from the European Union or the United States, they should understand the limitations of state rights better.

In short, even if it is the police, when encountering such a situation, it is communication between people, which is ten thousand times better than a cold official letter.

Jiang Yuan didn't mind using his personal influence. As an expert, reputation is also part of strength, so he said, "I have no problem calling, but I don't know anyone and I don't have a phone number."

"Don't worry, I will arrange everything later. When the call comes, just say a few words. Don't worry, we in the Beijing Bureau don't have anything else, but there are plenty of men who can do this." Cui Qishan felt a lot more relaxed as he spoke.

Those who have been criminal police know that there are two types of criminal police who are good at their jobs. One is the iron-footed type, who rely on hard work and courageously overcome all difficulties. The other is the relationship-based criminal police, most of whom are old criminal police with a long career and have acquaintances outside the city or even outside the province.

The acquaintances here are not just knowing each other, but must be mutually recognized to the extent that one phone call can finalize a matter.

Compared with the former, relationship-oriented detectives are naturally more scarce. Many detective captains of criminal police teams are of this type.

Cui Qishan is neither the iron-footed type nor the relationship-based type, because he is not a criminal policeman who is good at business.

But as long as Cui Qishan has Jiang Yuan by his side, it is enough.
