"Do a DNA test for the dog?" Sun Jie heard Bai Song's request and said, "Aren't you making things difficult for me? The testing center doesn't have the technology to do this."

"How could they not have this technology?" Bai Song asked, "This isn't Tianhua. Even if it's Tianhua, I've seen something similar in the Criminal Science Department before."

"Alas... this is you..."

"Please ask for me." Bai Song also felt that he was looking for trouble: "Am I too idle?"

"You are just idle..." Sun Jie sighed, "Do you know that it is very difficult to identify animals? To prove whether the DNA of two samples is the same, there is no mature technology in practice. Maybe it can be done, but it may not be used as evidence."

"Is it so complicated?" Bai Song frowned: "Can it be done?"

"Let me call you and ask." Sun Jie said, "This is really a new thing."

What Sun Jie said is correct. This DNA identity identification seems simple, but it is actually not that easy. The main reason is the lack of market.

For some unknown reason, the number of people doing paternity tests has skyrocketed in recent years and is increasing every year. Therefore, it is very simple to do paternity tests and identity tests, and the technology is very mature.

Currently, pet cloning is relatively rare, and only the largest cities have this business, not to mention direct DNA testing of dogs. Moreover, many institutions are not accurate at all, and the results given cannot be used as evidence.

The court is very strict in identifying evidence, especially when it comes to identification, which requires relevant qualifications before it can be used as evidence.

Sun Jie held the two yellow dog hairs that Bai Song gave him, feeling speechless. What on earth was he doing all day?

…

Wang Liang was very happy to see this scene, mainly because he was the busiest these days and Sun Jie was too idle. It was interesting to cause some reasonable trouble to Brother Jie: "So what are you going to do about today's incident, now that it's not a dog?"

"It's simple. We can just file a case ourselves and then start investigating the organization. If it's a minor matter, we'll transfer it to the East City Branch. If it's a major matter, we'll handle it ourselves." Bai Song said, "It's not difficult to file a case."

"That's you..." Liu Shuyuan said, "If police officers from other police stations found out about this, it would be much more difficult to file a case."

"Don't worry about it," Bai Song said with a smile, "After working so hard for so many years and growing to where you are today, it's always useful, isn't it?"

"That's right," Liu Shuyuan did not refute.

Given the current situation of this case, if we want to move forward, we can only wait for DNA identification, which will not be a matter of one or two days. It is not so easy for Sun Jie to find someone to help, because each identification center has a lot of urgent work to do, and it is really a waste of resources to identify dog ​​hair.

If it was half a year ago, Sun Jie would not have been able to do this, but now he can try.

This matter had to be put aside for the time being. Bai Song sat down with everyone and held a meeting to talk about the Guo Liao blackmail case.

Ren Xu has already arrived at the department, but did not come to the anti-fraud center. Instead, he continued to study and receive training there, so Bai Song and five others are still here.

"Sometimes I don't understand some things," Wang Liang said, "Why is it that no matter how much we promote it, more and more people are being deceived?"

"Weakness and incompetence have never been obstacles to survival, but arrogance is," Bai Song said. "There is a sentence in the book The Three-Body Problem that I read recently, and it is really true. Sometimes when we promote anti-fraud on the Internet, many people sneer at us, thinking that they don't need to read it."

"Well, especially those scams in fruit chats," Wang Liang said, "I looked and found that most of them are college students, graduate students or people with good jobs. Only these people will give money to the other party for the sake of face."

"Do you have a function for this?" Bai Song asked, "It's the specific data of people with different education backgrounds and jobs who have encountered Fruit Chat fraud."

“Yes,” Wang Liang said, “but these cannot be made public. If they are made public and known to the bad guys, they will use our big data to carry out targeted blackmail.”

"That's true...just give me a copy privately later." Bai Song thought for a moment and asked, "How's the IP tracing going?"

"It's not very smooth. The technical strength here is already very good, but it is still very troublesome." Wang Liang sighed.

"Why?" Sun Jie was a little curious: "You can't do it either? So, what are the difficulties in investigating these cases?"

"Brother Jie has not been involved in this matter, so let me give you a general idea," Wang Liang said, "First, the scammers are very mature. They have professional teams and can do some geographical disguises. Basically, all the IPs we track down will end up in Southeast Asia. Visas to these places are too easy to get, and they are close. The local governments are weak, and the police are not good... The second is their identity disguise. There are millions of identity cards lost in my country every year. The black market and other places can provide scammers with a steady stream of identity information. Not only that, there are too many Internet companies now, and too much personal information is leaked. The Internet company went bankrupt, and some information could not be supervised in time, which directly caused chaos; the third is the account problem. The rise of mobile payment has made the capital flow too fast. Money can be transferred more than 20 times in a few minutes. We can hardly catch up no matter how fast we check back, unless we can mobilize the data of all banks and major payment platforms at the same time and in real time, but this is unrealistic; the fourth is the low technical threshold. Many college students have participated in fraud. The difficulty of technical disguise is terrifying. Remember the fake base station we encountered in Tianhua? This kind of thing really does not require any technical content; the fifth... Oh, I won’t say it, it’s troublesome anyway! "

"Uh... let's not do it then..." Sun Jie felt a headache after hearing this: "This is much more difficult than dissection."

"You're right, because these things are invisible and intangible, unlike dissections which are physical objects," Wang Liang said, "but we are also very strong, and the number of cases we uncover is increasing every year. After all, the scammers only have so many tricks."

"If we had called 110 to ask more often when we encountered problems, it wouldn't have come to this." Liu Shuyuan sighed, "But this is not the time to blame others. Even university professors get cheated sometimes, let alone students?"

"So do we have to go to the places you mentioned to arrest people?" Wang Huadong said, "This is a good thing."

"This is totally different from what you think," Bai Song said, "Once you go abroad, your police ID becomes a souvenir. You are not qualified to arrest people. You can only contact local arrest teams and then we bring them back. So going out to arrest people is not as fun as you think. It's mostly just a formality."

"That's not right," Wang Liang said, "Do you remember the time you went to Nanxi Village? That's when we arrested Deng Wenxi? We were arresting people here, and Team Ma and others led people out, and some people were injured."

"You have a good memory, which is rare." Bai Song nodded. "It's not that strict over there. Sometimes they don't have enough manpower and ask us for help, which is normal, but this is not the norm."

"But then again, I don't agree if you go out," Sun Jie said to Bai Song, "Your identity is too special, you will be in trouble if you go out."

"I know," Bai Song said, "If I can travel all over our country in my lifetime, I will be very satisfied. No matter how exciting things are outside, I won't even take a look at them."

Bai Song is not a trouble-making person, nor does he have to show off his abilities. His body is not bulletproof and he needs to drink water and eat. If he goes out, some things will be hard to prevent. In fact, it is not just Bai Song. Many people in the security department, like Jiang Zhengwei, have never gone abroad in their lives.

"If you need anything, I can go and provide background support." Wang Liang raised his hand.

"It's rare..." Bai Song sighed: "Okay, let's not discuss this for now. Are all the IPs you analyzed from abroad?"

"Not really. Some of them are from Anhui Province. Are you planning to lead a team to catch them?" Wang Liang said, "I have already reported this to the anti-fraud center. It is not our turn to catch them."

"That's right..." Bai Song continued to chat with everyone: "Then let's take a rest for the next few days, and then we can discuss in detail if there is any situation."

…

Ever since arriving at the Anti-Fraud Center, Bai Song has been in this state: he actually wants to find a job, but there is never anything suitable to do.

Most of the clues encountered by the Anti-Fraud Center are delegated to various branches for handling. After providing the address of the scammer and other information, it is also handed over to the branch because they can only handle technical matters and it is impossible for them to handle all kinds of incidents in Shangjing City.

Therefore, if the Anti-Fraud Center doesn't arrest anyone, then Bai Song's position here naturally means he can't play any big role. How can this be acceptable to someone like Bai Song?

So he kept trying to find something to do, but couldn't find one.

There was a murder case in Shangjing every few days, and each case was solved within eight hours. There was no need for Bai Song and others to take action.

This is actually the normal working state of many department leaders. Others are very adaptable to it, such as Wang Liang and Sun Jie, who are naturally adaptable, but Bai Song is not so good. He has been idle for the past two months and has become ill.

In the evening, Bai Song called an online taxi and took it back to his residence.

He still lives in the same place as everyone else, but now everyone has their own things to do, and they don't usually go back together. On weekdays, Bai Song would definitely take the subway, but recently he always takes a taxi.

I don’t know what’s going on, but taking a taxi is really cheap this year. Didi and Uber are competing fiercely. Bai Song only needs six or seven yuan to take a taxi back home, which is something he would never dare to think about on a normal day.

"You are so young?" Bai Song usually likes to chat. When he got in the car and found that the driver was only about eighteen or nineteen years old, he asked.

"22, not small anymore." The driver checked the navigation system and said, "You live in the city center."

"We share the rent," Bai Song said.

“Oh, that’s not bad.” The driver said, “It’s not easy to settle down in Beijing.”

"I think you are from Henan Province, right?" Bai Song asked, "Why did you travel so far to do this?"

"Can you tell where I'm from?" The driver glanced at Bai Song and then looked at the road: "I've been in the south for four or five years, and my accent is basically Mandarin."

"Oh, I'm just more familiar with Henan Province," Bai Song was just chatting casually. He didn't say that he could actually recognize accents from all over the country.

"Yeah," the driver nodded. "You're awesome. I'm driving this car with my brother. We rent the license plate for 800 yuan a month. We bought the car with a loan. We've been driving in Beijing for almost a year and we've earned enough to pay for the car."

"That's quite profitable," Bai Song said, "Your Camry must be worth more than 200,000 yuan."

"He runs for 12 hours, I run for 12 hours, and we change shifts at 8 o'clock in the evening. It will be our turn soon."

"Isn't this tiring?" Bai Song was a little shocked. 12 hours a day was too scary.

"To make money! Now the two companies are fighting, even though you can get a cheap taxi, we also get a lot of rewards, otherwise we wouldn't buy such a good car to run this. I can make 700-800 yuan in net profit during the day, and a little more at night. Together we can make 30,000-40,000 yuan a month." The driver said, "If their companies fight for another year, we can save enough money to go home and get married."

"You are really hardworking," Bai Song had to admit. Most people could not stand running like this every day.

"I don't know what you do. My brother and I didn't go to school. We used to work in an electronics factory. In recent years, they have started using robots, and the cost of workers has become lower and lower, but the boss has a sullen face every day, as if we owe him money! Come here to drive a taxi, you can earn money even if you work hard! And you do it yourself! Of course, we all know that this kind of thing will definitely not last too long, but we earn every day. This car has traveled more than 100,000 kilometers, but Japanese cars still retain their value. Even if we don't do this in the future, we both still have a good car and have saved some money!" The driver saw things very clearly. The reason why they worked so hard was that they knew that this kind of high salary with benefits would not last too long.

"That's true. It's not easy to make money nowadays!" Bai Song nodded.

At this moment, there was a traffic light, and the driver sent a WeChat message to his brother, telling him the address for a while.

When the car arrived, Bai Song found out that the driver's brother had taken a taxi.

"Why don't you go pick him up?" Bai Song asked.

"It's cheaper for him to take a taxi than for me to pick him up like this." The driver said as a matter of course.

"Uh..." Bai Song felt this was ironic: "Then how are you going to get back to your place later?"

"I'll take a taxi to the subway station, and then take the subway back." The driver said, "I'm leaving!"

Bai Song waved goodbye, but felt an indescribable awkwardness.

These taxi companies are burning money to fight each other, forming this deformed supply and demand market, but this is just the beginning. Once the burning of money stops, all taxi drivers will become blood banks for capital.

But, for now, who is wrong? No one is wrong.

Thinking about these things, Bai Song slowly returned to the community. He saw a police car at the gate of the community. He went to ask about it and heard that an electric bike battery was stolen.
