Chapter 36: Gold Powder Hermès

The 8 cameras in Jiang Village residential area covered the entrances and exits and 2 electric scooter parking points inside and outside.

The electric scooter parking point inside was covered with a rain shed, and the open-air one outside was facing the street, neither of which affected the enthusiasm of the thieves.

After watching the video surveillance for a long time, Mu Zhiyang and Jiang Yuan discovered that there were only 3 people who came to steal electric scooters.

One was the man in the windbreaker who might have left fingerprints under the I-beam. He was about twenty years old and basically used a master key for violent lock-picking. After coming a few times, he didn't come again, probably because he was afraid of being recognized by security guards and the like.

The other two were a gang, even more violent. They came twice in total, both at night, driving an electric tricycle, stopping next to the electric scooter parking point outside the door. Seeing electric scooters without locked ground piles, they cut the fuse next to the battery, then pasted a magnet on the horn to solve the alarm, and moved them away directly. For electric scooters locked to piles, they used hydraulic pliers to cut the chain locks or U-locks locking the cars, and then moved them onto the tricycle, stealing multiple electric scooters at once.

Jiang Village residential area belongs to the edge of the county town. The south bank where the county government is located is relatively prosperous, while the north bank is some newly built residential areas and streets with incomplete supporting facilities. The criminal suspect stole the electric scooter and turned three times, which was equivalent to leaving the city. There was nowhere to look for it.

"All have no technical content." Jiang Yuan finished watching the surveillance video and took a picture of the scene where the transport group threw cigarette butts and garbage into the drainage ditch on the side of the road to his mobile phone. He couldn't help but evaluate.

The thing he imagined before, or thought, that driving an electric scooter at least requires lock-picking skills, was not reflected in the two groups at all.

Moreover, from the perspective of efficiency and practicality, the methods adopted by these two groups were actually better than the lock-picking mode.

Because technical lock-picking ultimately requires a little time. No matter how fast the lock-picking is, it is nothing more than the same as the violent lock-picking of the first group, twisting twice to open it; it is impossible to be faster. And if the speed of technical lock-picking is slower, it might be suspected by others.

Mu Zhiyang said happily: "They are all stealing electric scooters, what technical content can they have? There are even worse ones, who don't even know violent lock-picking, just wandering on the street, seeing whose electric scooter key is forgotten to be pulled out, and immediately sit on it and drive away..."

"Then what if you don't encounter an electric scooter with the key forgotten to be pulled out?"

"Go home, make instant noodles, and continue playing with mobile phones." Mu Zhiyang curled his lips and said: "There are also those who specifically steal battery accumulators, which are not much higher than this."

"So, these three people still have pursuits?"

"Isn't it. Just these two using hydraulic pliers, you look carefully, they are all prioritizing cutting the lock head. Why, because the lock fork can be made very hard, but the shape of the lock head is complex, so the hardness cannot be high. If it is high, it cannot be processed, or if it is processed, it is too expensive. That's what it means..." Mu Zhiyang also relayed what he heard, but he said it quite clearly.

Anti-theft things ultimately have to pay attention to cost-effectiveness.

A 20-yuan U-lock can only defend against passersby, not against violent lock-picking like the windbreaker. A 60-yuan U-lock can basically defend against the windbreaker as long as the locking position is correct, but it cannot defend against the moving-house flow like hydraulic pliers.

The alarm system that comes with the electric scooter is the same. An alarm with its own power supply is more practical than an alarm connected to the battery. An alarm with two horns is more troublesome than one with one horn. However, no matter how good the anti-theft system is, it is afraid of encountering the right person, especially the standard anti-theft system, which is like an "example question" in a book. No matter how difficult the example question is, it can only defend against those who don't read books, not against those who are smart and eager to learn.

The best anti-theft mode for electric scooters is for the car owner to make some personalized changes to their own car's anti-theft system. It doesn't need to be an improvement or betterment; just changing the position and changing the mode a little bit will greatly improve the success rate of anti-theft. This is like slightly modifying the example questions in the book, changing the numbers, etc., which is enough to block those students who haven't studied seriously or are not smart and eager to learn.

However, they have fallen to the point of stealing electric scooters. The degree of serious study and the degree of being smart and eager to learn are just like that. Look at the clues they left behind and you will know. Any child who can score 120 in mathematics, no matter how bad the questions are, cannot be so careless.

Jiang Yuan and Mu Zhiyang each rode an electric scooter and first went to the Zoumadao Police Station next to Jiang Village residential area to report.

After some social interaction by Comrade Mu Zhiyang, the two successfully led out an auxiliary police officer to accompany them.

Although the auxiliary police officer brought an auxiliary word, in the current grassroots judicial system, he does everything and can do everything. Zhou Ta, who was wearing a police uniform with a police number starting with FJ, was over 40 years old and had 15 years of police experience.

Zoumadao Police Station was also afraid that the two young people, Jiang Yuan and Mu Zhiyang, didn't understand the situation, so they sent Zhou Ta.

Compared with ordinary police officers, Zhou Ta's social ability was quite good. After walking for a while, he became familiar with Jiang Yuan and Mu Zhiyang, and then said: "I often do on-site investigation work. In fact, if it's just to scan fingerprints, you just say a word, and we can go and scan it. No need to come specially..."

"I want to scan it myself." Jiang Yuan explained politely: "The fingerprint on the I-beam has been there for a month. I don't know if it can still be scanned."

As soon as Zhou Ta heard this, he immediately stopped the topic and turned to say: "In fact, it is not necessarily necessary to scan fingerprints. Ask around on the street, maybe you can find someone. These people who steal electric scooters for a living have no background. If you are willing to work hard, someone will always provide it."

"Then try it next time." Jiang Yuan was just helping relatives find electric scooters. It was already very troublesome to ask Mu Zhiyang and Zhou Ta to run a trip, so there was no need to create a human debt of people asking people.

Moreover, Jiang Yuan didn't understand the things on the street, so he didn't know how complex it would be to owe favors for this.

Zhou Ta determined Jiang Yuan's attitude in two or three sentences and then entered the chat environment happily. He patrolled nearby every day, and he knew clearly which shop's food was clean and which supermarket had rats, which was quite interesting.

When they arrived at the scene, Zhou Ta, wearing a police uniform, did the on-site record with great work enthusiasm. Mu Zhiyang followed Jiang Yuan and squatted in front of the I-beam, bent down and looked twice, and said: "How can you see if there are fingerprints left."

"You can use a magnifying glass, or ultraviolet light, etc. to look." Jiang Yuan spread out the investigation box he brought with him and said casually: "Our situation today doesn't need to be so troublesome, just scan the powder directly."

While speaking, I saw Jiang Yuan pointing his soldiers and generals, taking out one containing gold powder from several gold, silver, black, gray, and white bottles, and taking out a fluffy wine-black brush.

Looking at the position of the photographed photo again, Jiang Yuan dipped the brush in gold powder and flicked the brush handle lightly, making the 400-mesh copper powder fall densely onto the still flat steel surface.

From Mu Zhiyang's perspective, Jiang Yuan flicked it exceptionally evenly, and with his prelude, it was quite ceremonial.

"Doing technology is different. You have quite a lot of attention to this. We generally use silver powder." Mu Zhiyang, as a criminal police officer, also often scans fingerprints when appearing at the scene. For some minor cases, it is simpler to do it yourself than to ask people from the Criminal Science Squadron to come over.

Jiang Yuan observed the surface of the I-beam and said: "Silver powder has strong adhesion and is suitable for many occasions. It is a universal powder. But the background today is too light, so the contrast of gold powder is better."

"Your brush also seems different."

"Pure gray squirrel hair. Over 200 each, I specifically asked for it."

"This broken brush is over 200?" Mu Zhiyang was surprised.

"Gray squirrel hair is known as the Hermès of brush hair." Jiang Yuan flicked the brush and smiled: "Look at the tip of the hair, it's thin and straight, and soft, not easy to damage fingerprints."

"This is Hermès?"

"Because gray squirrel hair is also the best in the makeup brushes used by girls. It is comfortable to brush fingerprints, and it is also comfortable for girls' faces to be brushed by it." Jiang Yuan added: "It matches gold powder best."

Jiang Yuan spoke, lay down, leveled his right hand, and used the tip of the gray squirrel hair brush to gently brush away the gold powder on the surface of the I-beam, as gently as applying eyeshadow for a beauty.

As the excess gold powder dissipated, several incomplete fingerprints appeared before the eyes of the two. ===== CHAPTER 37 =====
