There is also a police officer with Liu Zhen, a white hat who applied for transfer from Mystery 5 to the Counter-Terrorism Office. White hats are people who have received professional network security computer training and are the main component of the network and computer technical staff of judicial agencies. Not

A hacker in the traditional sense.

For example: Liang Xi is now chasing a vehicle with license plate 123.

Non-technical people will call: Command Center, we want real-time 123 vehicle whereabouts, send the images to me. Command Center: Not available.

White hats can enter the traffic monitoring system through permissions, switch surveillance cameras with skillful operations, lock 123 vehicles as much as possible, and generate a trajectory of 123 vehicles walking on the map.

In addition to white hat tasks, hackers can also hack into 123 vehicle computers, hack into leasing companies to investigate car renter information, and use non-traffic monitoring to monitor 123 vehicles. By triangulating base stations and vehicles, they can search for signals from mobile phones in the car.

Even in the end, the phone number is locked and the phone is hacked.

Xiaobai is a girl, very young. At first glance, she can tell that she is a technician who has never been in the field. Technicians can also apply for field work, but they need to pass an assessment, mainly physical fitness and other aspects, and can only be accepted as an intern after the field supervisor agrees.

Attendance.

Liu Zhen was not satisfied with Xiaobai because Xiaobai could not get Gray's itinerary. Finally, he contacted Roger and Gray's office sent a simple itinerary.

How simple is it? I will meet with the acting mayor in the morning and be in the office in the afternoon. I will go to the director’s office tomorrow morning, and it has not yet been decided tomorrow afternoon...

Liang Xi looked at the itinerary: "What's the point of this? Xiaobai, centered on Gray's residence, collect the license plates of all vehicles that appear within a five-kilometer radius in the past week, and then conduct cross comparisons. In addition to license plate comparisons,

It is necessary to classify cars into rental cars and private cars. Gray's off-duty time is uncertain, but his work time is certain, because based on Gray's work time, all pedestrian faces that can be photographed by surveillance along the route of Gray's car are collected, and then a comparison software is designed.

Compare repeatability.”

Xiaobai held the laptop and looked at Liang Xi. She wanted to cry and go home.

Liang Xi had no choice but to contact Sela: "Sela, are you busy?"

Sierra: "I'm not busy. Is there something wrong?"

Liang Xidao: "There is something wrong with the Anti-Terrorism Office. Where are you? Liu Zhen went to pick you up."

…

Xiaobai sat aside and was dumbfounded watching Sera's operation. In her opinion, what Liang Xi ordered was a pyramid-level project. Under Sera's operation, Liang Xi's request was just to cook a bowl of instant noodles. The results were obtained in less than five minutes.

: "Faces are still being recognized and cars have been classified."

Liu Zhen drove a van and parked it at the edge of the park. Liang Xi and Sera sat in the middle, and Xiaobai sat in the back seat. Liang Xi leaned next to Sera and looked at it for a while, then asked: "Do you have a deck?"

Serra said: "Exclude the second-level decks."

Assume that the license plate number on the pickup truck is the license plate number of the car, which belongs to the third-level license plate, which is clear at a glance. Assume that the Chongxia brand car is matched with the Shuaixia brand car, which belongs to the second-level license plate and can be intuitively identified from the information of the Vehicle Administration. 1.

There is a problem with premium decks. They are the same brand, same model, and same color. It is impossible to judge the authenticity through remote monitoring.

Liang Xi looked at it for a while: "The burger shop next to the supermarket." The burger shop is on the right side of the supermarket, and the right side of the burger shop is the parking lot of the supermarket. In the record, a black car left the burger shop twice at 8:20 a.m.

Exit the parking lot on the right, drive once in front of Gray's car for about five kilometers and then turn right, and once drive three kilometers behind Gray's car and turn left.

Sierra mobilized the surveillance video and adjusted the time. For the first time, starting from 8:10 a.m., the black car did not move. At 8:20, the black car started to drive out. Pulling the surveillance camera forward, it was found that 8:50 a.m.

Black car enters parking lot.

Liu Zhen asked: "You bought food outside, do you want to eat in the car?"

Liang Xidao: "Since you have plenty of time to eat in the car, why not throw away the food waste? The trash can is less than five meters away from the car. Serra, second time."

The second time at eight o'clock, the black car entered the parking lot. At eight o'clock, the burger restaurant employee went out and handed a paper bag of take-out from the driver's seat. After taking the take-out, the driver closed the window. At eight-twenty,

The car drives away.

Serra said: "The owner of the car is a Londoner named Ryder. He is 65 years old and lives near Baihan Community. He lives with his wife. He and his wife left the country for Finland a week ago and have not entered the country yet.

Close the record."

Liang Xixiao: "Unmanned driving." Of course it's not driverless. The gangster may have taken the license plate or borrowed Ryder's car. Maybe it was their arrangement for Ryder and his wife to travel to Finland.

Serra said: "The target vehicle's phone number for contacting the burger restaurant was found, and it was a prepaid phone. In addition to making calls to the burger restaurant, this phone card received four calls with unidentified numbers."

Liang Xi asked: "Liu Zhen, what do you think?"

Liu Zhendao: "Do you think gangsters will live in Ryder's house?"

Liang Xidao: "This is a very smart method. I went to Paris to commit a crime. I didn't want to stay in a hotel, and I also wanted safe transportation. There is a good way to give a pair of elderly people a travel award and let them go out.

Traveling. Why old people? Because they have no work needs and have plenty of time. They can go when they want. The car cannot be taken away, and the car keys will not be taken away, so I can borrow the car. In this way

, not only have a place to live, but also a car to use.”

Liang Xidao: "The most important thing is the location of Ryder's home. His home does not belong to Baihan Community, but outside Baihan Community. His home is relatively remote and is not included in Baihan Community. Community police will not pay attention to them.

We won’t come to them at home or in community activities. Ryder’s situation is completely tailor-made for gangsters. But...it doesn’t have to be gangsters.”

Liu Zhen asked: "Huh?"

Liang Xi said: "I am very confused. If the bad guy is smart enough, for example, as smart as me, then we cannot touch Ryder's line. If the bad guy is not smart enough, there are gangsters living in Ryder's house, and the gangsters drive Ryder's car.

, approached Gray's car at close range twice, and they had launched an attack."

Liu Zhen disagreed: "Gray's car is a bulletproof car. They followed Gray's car in the hope that Gray would get out of the car."

Liang Xi accepted and said: "Move or not? I don't know whether the bad guy is smart or not." If Gray is not riding in a bulletproof car, it means that the bad guy must be smart. If Gray is riding in a bulletproof car, then it is impossible to judge whether smart or not is smart.

No. If you are smart, you can't touch the Ryder line, which will alert the snake. It is not ruled out that the bad guys deliberately set up an exposed point to judge whether the police began to suspect that Gray was at risk of being killed.

Serra reported: "Someone has been staying at Ryder's house this week." From the background, residents' electricity consumption can be monitored through smart meters.

Liang Xi asked: "Has the face comparison produced any results?"

Sierra turned the computer screen: "Yes."

Liang Xi and Liu Zhen looked at it for a while and found nothing suspicious. Liu Zhen asked, "How about scraping the car?"

Liang Xi: "Scrape the car?"

Liu Zhendao: "What we often do in the anti-fan team is to deceive criminals out of cars by causing small traffic accidents. Or to prove whether there is the person we want in the car."

Liang Xi said: "Garbage."

Liu Zhen didn’t understand: “Trash?”

Liang Xidao: "You must dispose of garbage within a week of living here."

Liu Zhen: "Garbage truck?"

Liang Xidao: "If the Ryder line is a warning line, the residents of Ryder's house don't have or need to take too much precautions, because they are just waiting for the police to come. They will put their garbage in the big trash can at the door.

.If they didn’t put the garbage out, it means they were very careful and took the garbage far away, then they are the real owners we are looking for.”

When Liu Zhen heard this, she stretched out her hand and palmed Liang Xi's hand. This made perfect sense. She liked that Liang Xi had a mind that could solve the biggest troubles in the simplest way.

…

The answer was soon revealed. Liang Xi guessed correctly, the Ryder Line was the opponent's alarm. As a result, the opponent's identity changed from a monster to an elite monster, and things began to get complicated.

"If we investigate Gray's security issues, we will find problems with the Ryder family. Once we know the situation, we will definitely take the Ryder family back for investigation. This is police logic, this is law enforcement norms, and the other party has committed criminal acts such as illegal intrusion.

, this approach is impeccable. The problem is: once they act, the bad guys know that the police have begun to consider Gray's personal safety and have invested a certain amount of resources to protect Gray. On the other hand, the gangsters in Ryder's house have not been alerted or investigated, which shows that

No one considered Gray's personal safety, including Gray himself."

Liang Xi analyzed: "There are two methods of assassination. The first method is tracking, looking for opportunities, and assassination. This method is relatively common and is a typical European and British method of doing things. It is also the method that the bodyguard police will mainly prevent. Ryder

Gangsters played this role. The second way is to stay in position to assassinate. Gangsters master the pattern.

Lei has a certain behavior, such as going to a certain restaurant to have a cup of coffee in the morning, or taking a walk at eight o'clock in the evening. Since the gangster Ryder has performed the first behavior, the killer will most likely perform the second behavior.

We need someone who knows Gray well enough to help us find Gray's inevitable behavior."

Gray lives in a public community, and a large proportion of the surrounding neighbors are public officials or government employees. There are homes of middle- and high-level police officers in the surrounding areas. The security measures in this area are relatively good, and the risk of a direct attack on Gray's residence is extremely high. Guns

As soon as the sound rang out, within a minute, there were police officers in pajamas nearby with guns drawn to support them.

Gray's car is a bulletproof car. It was the car of former Assistant Director Downer. Downer received many death threats during his tenure. For safety reasons, the Special Operations Department allocated a bulletproof car to the frontline police department. The level of bulletproofing is not the same.

It is considered high, but it is much stronger than ordinary cars. In fact, many police patrol cars are also modified cars. The doors of the vehicles are reinforced with steel plates, which can effectively resist bullets. Ordinary pistol bullets can easily penetrate the car doors, and the doors are not bulletproof.

Gray works at the police station, so if Gray insists on the two-point and one-line daily routine, the gangsters can only attack by force. Under the attack, even if Gray can be killed, the price paid will be quite high. Gray is a front-line police officer, and he is accompanied by a

The bodyguard police officers of the Special Operations Department and the gangsters may be killed by Gray. The more people who go there, the greater the losses. What's more, there are fixed patrol cars everywhere now. Whenever there is a firefight, there will be at least two of them within a minute.

The designated patrol car arrives.

Since the bad guys figured out a way to turn Ryder's gangster into a siren, it showed that the planner was careful. Therefore, Liang Xi speculated that the most likely possibility was to assassinate Gray.

"Invade Gray's phone?" Sierra was startled: "Assistant Director Gray?" The Frontline Police Department is the most important department of the National Police Department. As Assistant Director Gray in charge of the Frontline Police Department, Gray can be said to be the second-in-command in the British police.

Its status and influence are second only to the Director of the Police Department.

Sierra shook her head repeatedly: "No, I won't do it." Don't forget that you have a good identity. Because of Liu Zhen, you can hack into some public facilities. But the nature of hacking into Gray's mobile phone is different.

This morning, Xiaobai has been staring at a few people in the back seat of the van, without any sense of participation. In her opinion, she, Liu Zhen, and Liang Xi are not from the same world at all. What makes Xiaobai sad the most

It was Sera, and her overwhelming aura made her dare not even cough loudly, for fear of being discovered that someone like her existed.

It was only then that Xiaobai found some sense of presence and raised his hand: "I said..."

Everyone looked at Xiaobai together. Xiaobai was frightened and whispered: "Gray is my uncle."

Everyone continued to watch, and Xiaobai whispered: "Uncle."
To be continued...
