It can be said that it is a very large investigation to check hotels and B&Bs in 6 cities and multiple counties at once, but in Xu Taining's case, it is probably just a sprinkle of water.
Xu Taining himself has work to do, and it is impossible for him to come here for such a small investigation work - if he comes, he will definitely be in charge of the overall investigation work. Just to investigate the suspect's accommodation location, Xu Taining is indeed not needed.
Jiang Yuan divided the task into six cities and counties' criminal police teams to do it themselves. It involved two provinces and more than one city, and it was indeed a bit difficult to unify the action. If the provincial departments were invited to come forward, they could only communicate, but unified leadership would require
More advanced units appear.
At this time, it depends on the capabilities of the criminal police teams themselves.
One thing to say is that it is very unreliable to expect all six criminal police teams to be very reliable. An organization is more complex than a person. From a simple point of view, people will have headaches and brain fever, and organizations will also have it.
period of change. As for more complex states, it will even affect work efficiency.
Therefore, why is it said that Xu Taining's plans always make leaders generous? Even the stingiest leaders often can't help but be tempted when they hear Xu Taining's plans.
For example, this six-county plan does not actually require all six criminal police teams to be reliable.
If you follow Xu Taining's direction to investigate, you will either end up in vain - the direction is wrong. The criminal did not park the car in the nearest county or city at all. He just returns to a fixed nest every time, or drives to the crime location all night without advance notice.
Arriving, snatching the child and running away, or sleeping directly in the car, etc., may not be investigated.
Or, if human traffickers are not so hard-working and simple, then they will not only stay in one place, but will stay in every place in advance. After checking the spots, they will then carry out the task of stealing children, and then leave after robbing them.
The probability of the latter is obviously higher, and if this is the model, even if the criminal police teams in one or two places are not reliable enough, the criminal police teams in other places will give the answer.
In terms of fault tolerance, Xu Taining’s solution is already fully utilized. The cost of each item is actually not high.
In a similar investigation, the biggest expense is travel expenses. Because the police do not get overtime pay. In units with less money, the criminal police officers pay for their overtime meals with their own money. In units with more money, they just provide one meal and more.
A bottle of salt soda belongs to a wealthy family.
Therefore, in summary, the investigation plan that Xu Taining came up with in only a short time turned out to be the most reliable investigation direction in the entire case. Of course, it is also the most expensive of all investigation directions at present.
But Jiang Yuan believed that if Xu Chu had taken action himself, he would have come up with a more expensive and better plan.
…
Jiang Yuan did not follow him to investigate the hotel. Whether it was done by the criminal police, the security brigade, or the police station, it was very cumbersome and did not require the skills of the criminal department. It was the tradition of the iron feet.
Artistic skills.
Several other investigation directions are actually similar, including special cases, cyber security or ex-convict routes, etc., and Jiang Yuan is not needed.
Jiang Yuan chose the nearest crime scene in Qingshi City to see.
Although it is an outdated crime scene, and there are no traces of blood, DNA or the like, the first scene is always important. Moreover, it is not modest to say that Jiang Yuan’s crime scene investigation capabilities are truly the best in the country.
Top level.
On the other hand, Jiang Yuan was also doubtful that the surveillance failed to capture any useful information.
The current Skynet can be said to be very mature. It cannot be said that there are no omissions. There must be a lot of loopholes. After all, it is a government project.
However, generally speaking, the best-effort wisdom of criminals cannot cover the deliberate stupidity of administrators. This is the advanced experience of Chinese social governance since Emperor Taizong of the Tang Dynasty.
It is quite difficult to completely avoid surveillance, even if you have visited the points and checked the route in advance. The key point is that a gang of human traffickers who rely on robbing children to make money has evaded surveillance six times in a row. Is this execution ability a bit excessive?
Stronger.
Jiang Yuan took a car for more than two hours before arriving at Lanhua Township, Cuigang County, Qingshi City.
It only took twenty minutes to leave Qingshi City, and only forty to fifty minutes to enter Cuigang County. However, the thirty or forty kilometers from Cuigang County to Lanhua Township took a full hour.
??????????.??????
The crime occurred in Jide Village, south of Lanhua Township. Locally speaking, this is a large village with a small village, a small supermarket and a sports ground in the village, and more than 200 elderly people and children living here.
.There are people from nearby small villages who come to the village primary school in Jide Village to study and buy things.
However, the village itself does not have surveillance systems, including the small supermarket in the village, which is deliberately not installed with surveillance cameras.
The crime scene was on the road between the village primary school and the small supermarket.
This section of road is half a county road and half a village road. The village road is only a little over 3 meters wide and was only repaired in the past 10 years. The county road is a normal asphalt road that can accommodate two cars in parallel. It looks a little bit a bit awkward.
Looks like it's been in disrepair.
There is no surveillance within two kilometers near Jide Village, but if you look at the map, the criminal's gray van has to pass through the county road to reach Jide Village, and it must also pass by vehicles several kilometers away.
Stuck.
Since I haven't passed by now, Jiang Yuan used LV3's technical defense monitoring technology and LV6's "Picture Scout - Trajectory Analysis". On-site analysis showed that he must have found other paths and bypassed the stuck point.
There are many possibilities here.
One possibility is that the criminal was very smart, determined the location of the stuck point, and tried every means to bypass the stuck point without leaving any traces.
Another possibility is that the criminal was lucky and bypassed the stuck point for some reason.
In addition, it may be relying on local people or gang members who are familiar with the local area, or it may be due to time factors, entering late and leaving late - the local surveillance is old, and the video resolution at night is extremely low and the effect is very poor.
"Zhiyang, Yaowei, you two each drive a car, try to get around the two surveillance cameras here, and see what route you can take. One should go to the west, and the other to the south."
Jiang Yuan selected Mu Zhiyang and Shen Yaowei, and asked one more policeman to take photos in each car to see how difficult the detour route would be.
The so-called Skynet is also denser the closer it is to the central city, and becomes sparser the farther out it spreads.
As fixed monitoring points, it is unrealistic to expect them to form a tight and insurmountable network. It mainly targets people who are not familiar with this system.
In short, Skynet is also playing with poor information.
If a person wants to avoid Skynet's surveillance, there are many ways and means. However, daily activities are difficult to avoid, and deliberate avoidance will deform the movements. This is the impact of the entire system on professional criminals.
the greatest deterrent.
Of course, there are always methods, especially for organized crime, the strategies that can be used are difficult, but the police also have more than just surveillance.
Shen Yaowei and Mu Zhiyang returned one after another in less than half an hour.
"There are small roads that are easy to avoid." After Shen Yaowei got off the car, he consciously began to draw pictures on the paper and said: "There are at least two or three small roads that can pass the car. The stuck point is an intersection. The village in front of it is not only populated by people.
There are many, and there are also people who are engaged in large truck business and farmhouses. The road is very easy to walk and you can go around it without much effort."
Mu Zhiyang waited for him to finish, then stepped forward and said, "I'm going to the west, so it's easy to take a detour. However, I only found one road. It's an old road and it's not easy to walk on. You have to drive slowly."
"In other words, the detour itself does not require local people. As long as you know the location of the surveillance, you can easily avoid it." Shen Yaowei concluded, knowing very well what Jiang Yuan wanted.
Jiang Yuan only nodded slightly and asked: "Then how can we know the monitoring location?"
"Resources bought on the dark web?" Shen Yaowei is still very trendy.
Jiang Yuan was noncommittal: "It's possible."
Mu Zhiyang said at this time: "It is safer to take the bad road the whole way. The bad road I took should be quite long. Anyway, I just walked. There is no way to monitor it."
"It's not possible if the road is too bad," Shen Yaowei said.
Mu Zhiyang: "The county road we took here is pretty bad in many places."
"Whether it's a bad road all the way or not, if you want to avoid surveillance, you have to walk at least a part of the bad road." Jiang Yuan turned to Wang Chuanxing and said: "Communicating with several captains in the group can also be used as an element of investigation and inquiry.
