Compared with other government departments, the public security department has more troubled personnel.

There is no guarantee of funds, so they can only generate income in accordance with the law. Gambling and prostitution are involved in traffic fines. The common people have big opinions, the leaders are not very welcome, and the particularity of the work determines that it is difficult to show your face, and it is easy to show your buttocks.

Some people may say that it is easy to achieve results, and it is not enough to solve a few major cases.

If a major case occurs in the jurisdiction in three days, it means that the society is unstable and the social order is strict. If there are always cases with bad impact, the chief of the public security bureau will basically be the end.

It is unrealistic to rely on big cases to make achievements, and there is only "innovation".

For example, Liangzhuang is very good at "safe construction", and there is a good village in the key county. The finances of other townships and towns are tighter than the other, and the township party committees and governments have no money to support the police stations and no money to build any police offices, so the experience of building a "safe and good village" can only be used for reference and cannot be promoted.

The use of cutting-edge technology to investigate and handle difficult cases is a bright spot, which has opened the eyes of the county leaders, and the leaders may be able to approve funds or solve a few establishments when they are in a good mood.

Originally, he only planned to invite Secretary Guo of the Political and Legal Committee, and by the way, he invited the procuratorate, the court, and the judicial bureau to come over to see and gain knowledge, but thinking that this was a continuation of the special operation to crack down on abduction, Zhang Ju went down yesterday to make a special trip to the county party committee and county government, and asked Secretary Xie and County Magistrate Yang and Deputy County Magistrate Guan and other county leaders to come over for inspection and guidance.

County Magistrate Yang didn't have time, Secretary Xie, Deputy County Magistrate Guan and Secretary Guo of the Political and Legal Committee came.

The conference room on the third floor was full of people, and the front of the building was full of leaders' cars, including the chief procurator, the deputy chief procurator, the president of the court, the vice president of the court, the director of the judicial bureau, and the deputy director of the judicial bureau...... It's like a county-wide political and legal work conference, thinking that he is about to become the protagonist, and he is worried about returning home.

"Han Suo, why don't you try it, this is not drinking, real knives and real guns, I'm afraid I'll drop the chain. ”

"You have more interrogation experience than me, and besides, I have my job, and I want to report to the leader in the conference room. The opportunity is rare, and others don't have a chance to show their faces yet, so take advantage of it. ”

There are more people who will be interrogated, why do you have to let yourself go, besides, this case is not complicated.

Gui Jiahao took a few deep breaths, raised his head and said, "Okay, just show your face once." You go up, don't let the leader wait, I'll hurry up and look at the case materials. ”

"Order another one, old man, you old comrade, you are fine. ”

Han Bo felt a little funny, stuffed the cigarette into his hand, and carried the leather bag with Director Ji, who had been waiting for a long time, to go up to the third floor together.

The county's anti-abduction campaign has just ended, and the Public Procuratorate and Justice Department is the main force in the operation.

The two abducted women were raped and pregnant, but the two suspects who bought them insisted that they had not touched them, and almost all the leaders of the procuratorate, the court, and the judicial bureau knew about it, and the commander-in-chief of the operation, Secretary Guo, had heard about it.

The case was transferred to the Liangzhuang Police Station (Anti-Abduction Squadron), the women were temporarily placed in the old Liangzhuang Party School, and the suspects were detained in the detention center.

"Secretary Xie is good, County Magistrate Guan is good, Secretary Guo is good, and the leaders are good ......"

After filming the activities and the conference, Director Ji became a cameraman in the bureau, holding a small camera sponsored by his subordinates, saying hello to the leaders and taking close-ups of the leaders. People who are dozens of years old play with such advanced equipment, it looks funny and funny.

Secretary Xie had a good impression of Comrade Xiao Han, and it can be said that he had something to do with him when he came to the Public Security Bureau today, so he couldn't help but joke: "Director Xiao Han, did you lend him your director's camera?"

Because of the old cadres, Deputy County Magistrate Guan and Secretary Guo have been to Liangzhuang, and they are deeply impressed by the habit of the police in Liangzhuang Police Station who like to use cameras to shoot when they have nothing to do.

"Report to Secretary Xie, the director's camera is from the government, and our camera is downstairs. ”

"Shoot today?"

"Shoot, the director ordered to film the interrogation process and hand it over to Liu Jian. ”

The subordinates were very competitive and had a long face, Zhang Ju was very satisfied, and smiled sideways: "Secretary Xie, video evidence is also evidence." From now on, when we encounter some cases in which the suspect is very likely to retract his confession or even frame the police handling the case to extract a confession by torture, we will film the interrogation process and turn the case into an ironclad case. ”

Secretary Xie asked with a smile: "Director Zhang, so you plan to equip a few more cameras?"

"There is a plan for this. ”

"It's a pity that County Magistrate Yang didn't come, so you can only go back and report to him alone. ”

It's almost the New Year, the streets and alleys are in a festive atmosphere, the party and government organs are going to celebrate the New Year, and the relationship between superiors and subordinates is not as strict as before.

"No kidding, let's get down to business. ”

Secretary Xie waved his hand and said with great interest: "DNA identification, I have seen it on TV, I have seen it in newspapers, I used to feel very sci-fi, but later I found out that it was true, and I felt very far away from us." I didn't expect DNA to be so close to us, and it was really applied to case solving. Today is here to open our eyes, let's get started, and give us an introduction. ”

"Xiao Han, you have been 'studying' in 703 for several days, and you have reported to Secretary Xie, Secretary Guo, County Magistrate Guan, and the leaders. ”

"Yes!"

There was a color TV and a blackboard in the conference room, and Han Bo took out a schematic diagram of the double helix structure that he had prepared overnight from his bag, and talked about it without slowness.

"The full name of DNA is double helix structure deoxyribonucleic acid, also known as deoxyribonucleic acid, the English expression, that is, deoxy daily wave nucleicacid, abbreviated as DNA, is a molecule, isolated by the Swiss doctor Friedrich Michel in 1869, it is the basic carrier of human heredity......"

"Since 1892, when the Argentine police used fingerprints as evidence to solve crimes, they have been quickly adopted by police around the world because of their uniqueness and reliability. Over the years, fingerprint comparison has played an irreplaceable role in solving cases, becoming ironclad evidence for verdicts, and is known as the king of evidence.

With the widespread dissemination of fingerprint evidence in films, television and books, fingerprint solving cases is now known to the world, so many criminal suspects come prepared, wearing gloves to commit crimes at the scene without leaving traces, making it difficult for investigators to find traces. ”

"In 1953, American scientists James Watson and Francis Crick used X-rays to diffract images of molecules with a double helix structure. For this, they were jointly awarded the Nobel Prize in 1962. The use of DNA to identify human beings was discovered in 1984 by British geneticist Alec Jeffries. ”

One autumn morning, inspiration flashed through his mind as he walked, and in the afternoon he began to devise ways to use DNA in criminal investigations. The following year, for the first time in the United Kingdom, DNA was used to acquit a suspect. The United Kingdom was the first country in the world to establish a DNA database, and the police compared the blood samples collected at the scene with the samples from the database, and many cases were solved after being matched......"

The preparation was thorough and simple, and the leaders listened with relish.

Zhou Shengnan, deputy procurator general of the county procuratorate, is a female leader, with a master's degree in law, shrewd and capable, and suddenly said: "Director Xiao Han, I personally appreciate your very forward-looking application of DNA identification technology to criminal investigations, as a prosecutor, I also know very well that DNA identification technology is widely valued by countries around the world because of its great power, but in my opinion, it is not absolutely reliable and foolproof, can you talk about its shortcomings." ”

This woman always picks on the thorns of the Public Security Bureau, but this time you are facing the most cunning little fox in our bureau. Zhang Ju was not worried that his subordinates would not be able to deal with it, so he got up and scattered a circle of cigarettes for the leaders.

A few days in "703" are not for vain "further study".

Han Bo said without humility or arrogance: "Report weekly inspection, I have consulted experts on this issue, and they said that DNA identification does have the possibility of errors, but the main factor affecting the correctness of DNA identification technology is not its own scientificity, but the problems and misunderstandings of relevant personnel in a series of operations. ”

"What do you think needs attention?"

If the public security bureau can conduct a DNA test, it will do it a second and third time, which is a new thing for the procuratorate, and the superiors do not have a clear text on the DNA evidence, which involves a question of whether to accept or not, Zhou Shengnan thinks it is very important to break the casserole and ask to the end.

The prosecutor with the highest education in the procuratorate felt very interesting to the police officer with the highest education in the Public Security Bureau, Secretary Xie and other leaders, and they smiled without saying a word.

"Report weekly inspection, as long as it is a human being, it will be wrong, from the moment I walked into the 703 biological confirmation room, I have been thinking about this problem, I personally think that we should pay attention to three points: first, the collection, preservation and inspection of biological samples must be there and strictly follow the norms. ”

Han Bo took out a copy of the 703 specification from his bag, and said with a stern face: "In the Simpson murder case that occurred in the United States, Simpson's lawyer team questioned the police's sampling on the grounds that the police officer who collected evidence at the scene did not wear rubber gloves in accordance with the operating regulations when collecting evidence, let an assistant with insufficient technical level operate the evidence collection, the blood sample was not sent for testing in time, and left unattended in the hot car for too long. It is believed that the sampler may have replaced the blood sample collected from Simpson's home with the blood sample taken from the victim's body, thus playing a decisive role in Simpson's eventual acquittal. ”

This case is so famous that it was reported on the news network, and the leaders nodded their heads.

"Second, it's not my point of view, it's the opinion of experts, who believe that it is necessary to unify the quality control standards for DNA identification technology. We have comprehensive normative measures in planning, organization and management, personnel, facilities, evidence control, validity confirmation, analysis steps, instrument calibration and maintenance, appraisal reports, reviews, accuracy tests, corrective measures, checks, and safety of the laboratory. ”

"The third point is exactly what we are about to do, we can't blindly trust DNA identification technology. ”

A leader was confused, raised his hand and asked: "Director Xiao Han, you just said that this technology can't be wrong, and now you say that you can't be blindly credulous, so is this technology believed or not?"

Just now we are talking about a technical issue, now we are talking about a legal issue, and the leadership is obviously confused.

Han Bo smiled and patiently explained: "Report Deputy Director Chen, I have studied a little law, and I personally believe that the conclusion of DNA identification should be the same as any other form of evidence, and it should also be verified in accordance with the law, and only if it is verified can it be used as the basis for determining the facts of the case."

In other words, DNA evidence, like all other evidence, is only one type of evidence that tells the truth, and is only meaningful if it establishes the necessary connection with other relevant evidence.

It is undoubtedly an overstatement to ignore the evidentiary relevance of other evidence, to believe that DNA evidence has the decisive function of incrimination, and to expect DNA evidence to tell the truth of all criminal facts. ”

Zhou Zhengnan nodded slightly, obviously convinced.

Zhang Ju was overjoyed, and couldn't help laughing: "Liu Jian, Zhou Jian, and Dean Chen, our Public Security Bureau is not all big and coarse, not only talented, but also high-quality talents like Comrade Han Bo. ”
