Police Detective

Southern Guizhou Province is too far away, and Bai Song is completely unable to reach out. According to Senior Brother Ren Hao, the probability of this case being a pure coincidence is higher.

Putting these things behind him for the time being, Bai Song checked the translation software, slowly completed the translation, took the equipment to the Cao detachment, and gave a general explanation of the company's situation and the status of the equipment.

"Literally speaking, this thing doesn't have the function of eavesdropping, right?" Detachment Cao felt relieved: "I will arrange for someone to study it later."

"Okay, then, Detachment Cao, I will continue to go out for interrogation tomorrow. Is that okay?" Bai Song asked.

"Go ahead."

After detachment Cao finished speaking, seeing Bai Song not moving, he was a little confused: "Why don't you leave?"

"Ecao detachment, can I apply for a car?" Bai Song prayed for his gas tank. People are poor and have short ambitions.

"Okay, use it, get it from Team Wang." After detachment Cao finished speaking, he continued: "But if there is a shortage of cars in the future, try not to occupy the bus. After all, if you go to arraign this matter, I can't talk to other leaders. speak."

"Thank you, detachment Cao!" Bai Song ran away happily.

In three to five days, we will be able to finish running to the more distant detention centers, and the rest is about ten kilometers away, so it won’t be a pain to use our own car.

After returning to the house, Bai Song contacted Wang Liang first.

Wang Liang took the high-speed train there and just arrived at his destination. He told Bai Song that the GPS coordinates were a bit troublesome and he might have to wait a while.

There was no rush, Bai Song knew that even if he knew the coordinates, he wouldn't be able to pass there for a while, and because other cars had taken away these suspected money goods, the coordinates might not be valid.

Bai Song asked Wang Liang. If he had other inquiries and needed to go to the local public security bureau to investigate relevant information, he could help check the car.

Looking at the entire Shonan Province, there should not be many such cars. I just don’t know if the local query system supports the search method of directly querying the car model.

After chatting with Wang Liang for a while, Bai Song discovered that the class's WeChat group was busy chatting.

Yesterday we talked about some strange cases at the police station, and the students were very interested. Of the thirty or forty classmates in Bai Song's class, less than half have gone to the police station, and most of the rest are in government agencies. There are also some such as Zheng Chaopei (who resigned) and Zhou Xuan who have not become police officers or taken postgraduate entrance examinations. Everyone chats in the group. very high.

At the current stage, most serious violent crimes such as homicides can be effectively combated, but many cases, such as telecommunications fraud, have not been able to satisfy the people.

The detection rate is not high, especially for small-scale fraud. Once a fake ID or username is used, the cost of crime is not high.

When Bai Song was in Team 3, many telecom fraud cases were committed by Wang Liang, but many of them could not be solved in the end. It was good that they could be handed over to Wang Liang. There are many small-sum scams in games, and some prices are as low as a few cents or even a few cents in RMB!

This is really not nonsense. For example, a game called Dungeon and Fighter was launched in China in 2008. At that time, there was a low-level game called Zombie King. It cost 3,000 game coins each time (according to the price at that time, it was about two cents). Many people Just collect the money and run away. This is of course a scam, and someone actually called the police.

There are really too many cases, too many fake information, fake IPs, and too many VPNs, all in all it is very troublesome. For this type of fraud, the best way is to combine attack and prevention. On the one hand, we fight against it, and on the other hand, we publicize and prevent it.

After everyone talked about this, they began to appeal to each other.

Do something together and do more publicity. If one more person sees it, one less person may be fooled.

It has to be said that there is still great power in large numbers. We organized some anti-fraud tips and everyone shared them through their own circles of friends and social accounts, and Zhou Xuan, a big V in the live broadcast industry, became an important figure in this event.

The most common fraud methods are summarized below:

WeChat and QQ directly send QR codes to borrow money (it became popular at the end of 2013, but this technology is just emerging now);

Online part-time jobs;

Investments with annual interest rates above 8%;

Brush scam…

…

This is a good thing. Bai Song suddenly thought that his blog seemed to have hundreds of thousands of fans!

After closing the notification, Bai Song logged into his own account again, forwarded what everyone had written, and then closed the blog.

After get off work in the afternoon, detachment Cao called Bai Song again and asked Bai Song to go there.

It seemed that the situation of the equipment was settled. Bai Song jogged all the way to Detachment Cao's office.

"No storage equipment?" Bai Song listened to Cao's detachment talk and was very puzzled: "What is this thing?"

"The technical department said it is a repeater, and the transmitting frequency band is ultra-short wave. The specific meaning of this was not mentioned in the report." Detachment Cao handed a brief report to Bai Song: "You college students, these are all top students, what are you doing? Let me tell you what it means."

Are the reports out? After all, it is something that leaders are concerned about, but it is different... Bai Song took the brief report and explained to Team Cao after reading it: "Our common Wi-Fi is ultra-high frequency radio waves with wavelengths at the centimeter level. , the transmission distance is short. This thing is a very high-frequency radio wave with a long wavelength, within the range of 1-10 meters, and a long transmission distance. To put it simply, our common FM broadcast is this kind of meter wave; the common AM Broadcasting is medium wave, and the wavelength is a hundred times that of FM.”

"Do you mean, this thing emits FM radio?" Team Cao understood. Everyone has used semiconductors.

"No, the power is far different. This is a repeater. The black radio station in Tianbei District before was not high-tech, but it was better because of its high power. This thing is an adapted repeater that can give those Black radio stations transmit signals for control and playback.

The black radio station cannot be directly connected to the mobile phone, but through this repeater, it can directly play the content on the mobile phone, and because there is no storage device, even if it is discovered by us, there will be no good clues. "

"This is not an ordinary criminal suspect." Detachment Cao nodded: "Since it does not involve the confidential issues of our corps, it's okay. But we can't take it lightly. The leaders of the corps know about this matter. Let's do it. Recently, you haven't been Do you want to go out to get the transcript? I will arrange a car for you. You take your drone and fly around the tops of high-rise buildings and some unmanned factories nearby. If you find anything else, tell me in time. "

"Okay, Detachment Cao, I'll go around more these days." Bai Song replied seriously.

"Well, I'll give you a key. Take it." Detachment Cao said, taking out a car key: "You can use this car as you like in the past two weeks. If it's unused, give it to Team Wang."

"Okay, thank you, Detachment Cao!" Bai Song was overjoyed.
