I am a super cop

Chapter 535 Writers and Fingerprints

For the hairstyle of the police, it seems that the board size is the standard, but the hairstyle of the official police does not have too many requirements in principle.

As long as it makes people look refreshed...

Of course, it is very unlikely that someone like H country in East Asia is so handsome that his bangs can cover his eyes.

Undercover cops are less demanding.

But police school students are different. From entering the police school, the first thing they have to go through is a haircut. All police school students must "shave their heads".

Of course, the bald head mentioned here usually refers to a very short board size.

This has something in common with the military...

Soldiers marching and fighting, especially during wartime, usually have to shave their heads before they can go to the battlefield, and when their heads are injured during wartime, surgery can only be performed immediately.

Therefore, practitioners in high-risk occupations usually have flat-inch hairstyles, giving people a tough performance.

However, in recent years, due to the leading role of film and television stars, more and more young people have begun to choose to shave.

There is a saying that goes well, if you are a handsome guy, you can tell if you cut your hair.

Hairstyles can conceal blemishes, but body size can better reflect masculinity.

He Junchao likes to have long hair because of his bad face shape, but it is difficult to get up in winter and his hairstyle is difficult to manage.

Therefore, He Junchao often comes to work with his hair on his head, and Jiwotou is often the object of ridicule.

But the attendance is okay, and there is a police cap to cover up.

But in recent years, many policemen don't like wearing hats, mainly because they find it troublesome.

But I have to say that the police cap is indeed the best choice to unify the spirit.

Gu Chen and Lu Weiwei like to wear police caps to enforce the law, with the national emblem on their heads, which represents righteousness.

"He Junchao." Officer Wang walked up to him, rubbed his head with his right hand, and said, "After lunch, go get a haircut. You come to work with your hair all day, it really affects the three groups." overall appearance."

"It's not that exaggerated, old Wang?" He Junchao scratched his hair, snowflakes fluttered immediately, and dandruff flew in the air.

"Look!" Police Officer Wang picked up He Junchao like a chicken, then flew up a jio, kicked He Junchao aside, and said loudly, "That's why you still don't want a haircut?"

Police Officer Wang looked around for a week, and said again: "Listen up, all three groups. I know that everyone has worked hard these days, but a hairstyle like He Junchao's makes people look decadent."

"So after lunch today, everyone's hair is long, and they are uniformly shaved into short cuts. Do you understand?"

"understood."

"Haircut again? It's cold."

"Okay! Now that the boss has spoken, let's go get a haircut."

The three groups of old and new comrades answered sparsely.

He Junchao, who returned to his seat, immediately gasped and said, "I said Lao Wang, so there must be a standard, right?"

"Standard?" Officer Wang turned his gaze back to Gu Chen, then pointed at Gu Chen and said, "Gu Chen is the standard, everyone shaved like Gu Chen."

"Ah? Isn't that too bad?" He Junchao quit at that time, and complained a little: "Everyone knows that Gu Chen is handsome and can control all kinds of hairstyles, but people with average looks have no way out." ? If you shave his hair like this, wouldn't we be even uglier?"

"That's right, let's trim the appearance, shall we?" Another old comrade complained.

Police Officer Wang said in a bad mood: "Let's unite together and make no compromises. From now on, we will have Gu Chen's hairstyle. I want Director Zhao to take a look and see the spirit of our three groups."

"Also, what's the matter with those fat people? Can you still gain weight in the third criminal investigation team? This shows that there are still not many jobs assigned to you. Hurry up and reduce it this month."

"Senior Brother Wang." A trainee policeman complained suddenly: "Sometimes people will gain weight once they get stressed. It's not because they don't have enough work."

"That's right. In our three groups, is there any chance of being lazy? The probability is so slim that it can be ignored, right?"

"Hehe, it may be that the dark dishes in the cafeteria are so delicious that we are all fattened up. I heard that Master Kong has recently researched a few new dark dishes, and they will be on the market at noon today. Tsk tsk, some of them ate them. "

"Okay, I see." Officer Wang walked to the middle of the office, and then said again: "Today, I just have one request, a haircut. I will come to check it in the afternoon. If I see that the side is too long, I will borrow an electric push knife to come over." , I will help you deal with it personally, but don’t complain about it when the time comes.”

After hearing Officer Wang's words, everyone dared not slack off.

If you want Lao Wang to get a haircut, it's better to go to a temple to become a monk.

……

……

At noon, the cafeteria of Furong Branch.

The dark cuisine studied by Master Kong may have failed, and many people complained repeatedly after making and eating the dishes.

It feels like everyone has been fooled. Some of them have played the role of guinea pigs for Master Kong to study the dishes.

Master Kong often studies some special dark dishes, and if he tastes them, they are not bad, and he will immediately push them to the cafeteria.

From the changes in the expressions of everyone during the tasting process, it can be judged whether it is necessary to continue to launch or stop here.

So whenever new dishes come out, Master Kong will sit in the corner of the cafeteria and quietly observe every move of the "little white mice" in the cafeteria.

Gu Chen, Lu Weiwei, Yuan Shasha, and Police Officer Wang spent a long time sorting out the materials, so they were the last to get off work and arrive at the cafeteria.

Seeing everyone's distressed expressions in the cafeteria, the fine Lu Weiwei immediately understood, and quickly reminded everyone: "It seems that Master Kong's 10th attempt at a new product failed again, everyone remember not to order those weird-looking meals. "

"It's true, Lao Kang, we're not guinea pigs." Officer Wang shook his head and picked up the stacked dinner plates.

Last time, out of curiosity, I ordered a copy of Master Kong's latest dark food. As a result, Police Officer Wang was exhausted and paralyzed in the toilet all afternoon, almost collapsed.

So since then, Police Officer Wang has also become shrewd. Every time he gets Master Kong and wants to innovate, he will deliberately lead everyone in the three groups to work overtime to waste the time in queuing.

In this way, the guinea pigs went on and on, but I was just playing around with the wind.

After finishing the meal, the four of them found a vacant seat and sat casually.

At this moment, Nie Xiaoyu suddenly appeared behind Gu Chen and patted Gu Chen's shoulder lightly with his right hand: "Brother Gu Chen."

"Xiao Yu?" Gu Chen turned to look at her, and smiled: "Long time no see, are you busy with homework recently?"

"Almost, but I want to write a novel recently." Nie Xiaoyu said, then walked to Gu Chen's side familiarly, pushed Officer Wang away with his butt, and then sat next to Gu Chen.

"Writing novels? Is Xiaoyu so good?" Yuan Shasha was also surprised, feeling that Nie Xiaoyu was a little interesting.

Nie Xiaoyu laughed dryly, quickly waved his hands and became humble: "It's okay, there are a few in our class who are writing novels, but they are all writing sweet pet novels, I don't want to write this type."

"Then what do you want to write?" Lu Weiwei asked.

"Want to write a novel set in the late 19th century, and then some of the things that happened in that era."

"Yo?" Before Nie Xiaoyu finished speaking, Police Officer Wang interrupted directly: "Yes, Xiaoyu, are you going to write a historical article?"

"History doesn't matter, I just want to write some stories with that era as the background, because when I was young, I heard some stories from my grandfather's generation, and I feel that there are many interesting stories."

"So I want to sort it out, write a short story, and participate in the website's recent essay competition." Nie Xiaoyu said.

"Yes." Gu Chen put down his chopsticks, and was the first to agree: "It's a good thing to participate in the essay competition, and I support Xiaoyu."

"Then I support you too."

"Me too."

Lu Weiwei and Yuan Shasha also hurriedly said.

For a while, everyone gave a thumbs up, feeling that Nie Xiaoyu was a bit powerful.

Only Police Officer Wang nodded reluctantly.

How difficult is it to write a novel?Anyone with a discerning eye knows it.

Police Officer Wang once started writing when he was in college, and ended up writing 10 books in a row. In the end, Officer Wang was so angry that he stopped writing.

So when Nie Xiaoyu came up with the idea of ​​writing a book, Police Officer Wang expressed his support, but his heart was still sour.

"Xiao Yu." Officer Wang turned to look at her and asked, "You write such a long-term story, is that realistic?"

"It must be." Nie Xiaoyu turned around immediately, and said solemnly: "I just want to write a work about the realistic theme of that era. The content in it is mainly about a very powerful detective who has been in various majors. A story between forces."

"However, what forensic forensic techniques were there in the late 19th century? I don't know too well. For this reason, I have been trying to find relevant information on the history of forensic forensics."

"However, in the end, I still found nothing. The earliest forensic and crime-related works I could find were around the 20s."

"If it's earlier... then I won't be able to find it again." Speaking of this, Nie Xiaoyu looked up at Police Officer Wang, explaining why he came: "Officer Wang, do you usually read a lot?"

"It's okay." Officer Wang immediately put down his chopsticks, and said calmly, "Let's not talk about knowing astronomy and geography, but at least the basic knowledge is still understandable."

"Then do you know what forensic tools might be available in the late 19th century? Can you tell me?" Nie Xiaoyu blinked and asked.

"This..." Officer Wang was stunned for a moment.

Originally, he just said it casually in front of Nie Xiaoyu, but he didn't expect that Nie Xiaoyu's question was a bit out of date, and it was also very serious.

19th century?What a distant era, Police Officer Wang was instantly dumbfounded.

Are you serious about writing novels with you, Nie Xiaoyu?
"You don't know?" Nie Xiaoyu asked first, then immediately waved his hands and said, "That's right, I didn't actually intend to ask you."

"Hehe, Xiaoyu." Police officer Wang smiled, feeling embarrassed, and quickly explained: "The time you mentioned is too far away, how can anyone know this kind of knowledge, maybe there is, but you can There are very few that I remember, and our Furong sub-bureau has none at all.”

"Really?" Nie Xiaoyu didn't believe it, turned around and asked Gu Chen: "Brother Gu Chen, what do you think?"

Gu Chen glanced at Police Officer Wang, with a slightly calm expression, and said, "Xiao Yu, the reason why it is difficult for you to find forensic forensic tools before the 20th century is for sure, because they were still very rare at that time, because forensic forensics is a modern science."

"Is that so?" Nie Xiaoyu nodded frequently, and then said: "I just said, I can't find so many materials, but if I use modern forensic forensics to write about that era, will there be any contradictions? Or not rigorous?"

"That's not true." Gu Chen shook his head, then slowly put down his chopsticks, and explained seriously: "However, there are a few exceptions."

"Huh?" Nie Xiaoyu was puzzled, she looked at Gu Chen in a daze, then quickly took out her small notebook, opened it and asked Gu Chen: "Which aspect are you referring to?"

"Yes... yes." Yuan Shasha was stunned for a moment, and quickly asked Gu Chen: "Senior Brother Gu, it seems difficult to distinguish forensic identification methods in this age, right? You say forensic identification is a modern science. Is there no source?"

"There are." Gu Chen paused, and began to use his professional memory to try to recall the materials he had read before.

In the mind, various lightning strikes in various brain cells, instantly reminding Gu Chen of the previous content.

Gu Chen's eyes lit up, and he said, "You can try to write something about toxicology."

"Poison... Toxicology?" Nie Xiaoyu was stunned, and quickly recorded it in the notebook, and continued to ask Gu Chen: "Brother Gu Chen, is this something from that era? Then what specific aspect should I write about?"

"Write about arsenic, because arsenic is a common poison that has been used for centuries." Gu Chen said.

Nie Xiaoyu continued to record, and then asked, "Which arsenic?"

"Left stone and right application."

"Yeah, I see." Nie Xiaoyu recorded it in full.

At this moment, Lu Weiwei, who was sitting opposite Gu Chen, was a little puzzled and said, "Is this 'arsenic' so important?"

"That's right, why haven't I heard of it?" Officer Wang thought he was not a good student, but he didn't understand any of what Gu Chen said.

It is equivalent to being at the same level as Nie Xiaoyu.

Gu Chen smiled and said seriously: "'Arsenic' is very representative in this period, but in most of its evil history, it has never been proven that it is the culprit of suspicious murders..."

Speaking of this, many police officers who were eating around began to face Gu Chen, and some even came to Gu Chen's side with their rice bowls.

Soon, a small circle surrounded Gu Chen, and everyone surrounded Gu Chen tightly like listening to a book.

"In 1775, the Swedish chemist Carl Schiller proved that arsenic could be converted into arsenous acid by using chlorine water." Gu Chen directly took Nie Xiaoyu's small notebook, wrote the Chinese characters and symbols of this element on it, and continued:

"If you then add zinc and heat this acidic mixture, arsine gas will be released."

"When this gas comes into contact with the cryogenic container, the arsenic condenses on its surface."

"So, when Cervelas used this technique in 1821 to detect arsenic poisoning in the stomach and urine of a poisoned person, the field of forensic toxicology was born."

"Hey!" There was a burst of exclamation at the scene, and many people suddenly realized.

Lu Weiwei was also surprised, and said with some admiration: "So this is the birth of the field of forensic toxicology. I heard about it in the police academy before, but I forgot it long ago. Didn't expect Junior Brother Gu to remember it?"

"It's okay." Gu Chen smiled lightly, and then said: "But it's a pity, since then, the progress in this field has been quite slow."

Everyone seems to understand but nods to each other.

"Does everyone know about Mark Twain?" Gu Chen asked casually.

Nie Xiaoyu immediately raised his hand and said, "I know, a famous writer."

"Yes." Gu Chen nodded, and continued: "Mark Twain knew the power of fingerprint recognition, and he used this technology in his two books "Life on the Mississippi" and "The Tragedy of Fool Wilson" .”

"He used a thumbprint in the former to reveal the murderer, and in the latter a fingerprint emerged during the trial."

"Oh my god, I like to intersperse this kind of content in this kind of novel." Nie Xiaoyu was delighted, and quickly grabbed Gu Chen's arm and shook it: "Brother Gu Chen, who invented fingerprints to solve crimes first?"

"This..." Gu Chen hesitated for a moment, and then said lightly: "Actually, what is interesting is that the plots in Mark Twain's novels were published earlier than Sir Francis Galton's fingerprint research."

"Isn't it interesting that the latter Sir Galton was knighted for 'discovering' the value of fingerprints?"

"My God!" Officer Wang was also surprised, so he quickly asked Gu Chen: "Gu Chen, so the writer Mark Twain was the first to use fingerprints in case novels, and that Sir Francis Galton , Just because you discovered the value of your fingerprints, you were awarded honors and titles? Isn’t that a big deal for nothing?”

"Yes, it's unbelievable that this can be awarded honors?"

"Wouldn't Mark Twain be crying in the toilet?"

"Haha, this is the predecessor who planted a tree for two people to enjoy the shade."

Many onlookers, new and old, couldn't help avenging Mark Twain.

Gu Chen smiled: "Although the writer Mark Twain wrote the relevant fingerprint crimes in his novels earlier than Sir Francis Galton, he did not value fingerprints to solve crimes."

"Later, Sir Francis Galton was different. He further promoted fingerprints to solve crimes, and only then did fingerprints be inferred in the future."

"So in any case, the contributions of both of them to solving fingerprint crimes should not be underestimated, but the latter is representative. However, to be truly systematic, another person must be mentioned, that is, the police officer of the city of La Plata, Argentina. Ambusetich."

"Uh!"

Everyone was stunned, because what Gu Chen said was not very clear to everyone.

I usually only know that fingerprints play a very important role in the handling of cases, but no one paid attention to how they got there back then.

For example, before the invention of the stethoscope, everyone didn't know that when doctors auscultated female patients, they felt the heartbeat on the patient's chest.

And once the stethoscope came out at that time, many doctors wanted to kill the inventor of the stethoscope. Of course, not many people know this situation now, it's just a reason.
