"Joseph Simmons, you're under arrest..."

"Hank stone, you're under arrest..."

"Benny Abraham, you're under arrest..."

On TV, scenes of live arrest videos, accompanied by passionate music, give people a special feeling.

The host's voice was even more uplifting: "ladies and gentlemen, what you are seeing now is the golden hour operation carried out by the Swedish police. As of today, the police departments in Sweden have arrested 1262 people based on the latest PCR technology, involving 843 cases, of which more than 90% are old cases. The most important thing is, ladies and gentlemen, Now what you've heard is the most incredible thing. There are 665 people, that is, more than half of the suspects have confessed. "

"Another 200 people, though they didn't plead guilty, were considered to have solid evidence and entered the trial procedure."

Another host's voice was not so excited, but also positive.

The first host gave a full laugh: "yes, Sweden's judicial system is going to be busy. Nearly 900 suspects have been confirmed. In just half a month, can you believe it? It's not just Sweden's progress, it's human progress. "

"The deterioration of public security in Sweden since February has come to an end."

"Yes, the disorder in Sweden can be declared to be over. Ladies and gentlemen, this is a time when there are no criminals left out. Why? Please look at our selected videos to explain what PCR is... "

In the twinkling of an eye, huge subtitles appeared on the TV screen

The killer of crime -- PCR!

Sweden, with only 9 million people, does not have many TV stations. Residents often watch TV programs from nearby countries, such as Germany or France.

However, today's Swedish TV station has received extraordinary ratings and attention.

In the next few days, there was a discussion atmosphere in Sweden.

And the number of new cases has indeed been greatly reduced.

If they commit a crime, they will be caught - criminals don't understand the principle of PCR, but according to their mode of thinking, if they make a mistake, they may be caught, it's worth making a mistake, but if they commit a crime, they will be caught, and the significance of committing a crime will be lost.

As a result, the police can devote more energy to old cases.

A large number of accumulated cases have been cracked. Moreover, with the rapid operation of PCR, more and more suspects have been identified. Only criminals in prison have been punished.

Sweden is originally a rich country with good public security. Compared with a chaotic country like the United States, Sweden's failure to crack cases is mainly due to two reasons: lack of clues or insufficient evidence.

PCR solves these two problems.

Sweden has relatively sufficient police resources and relatively few malignant cases. When the role of PCR is brought into play, its marginal benefits will be intoxicating in a short time.

As time goes on, the work pressure of PCR laboratory has rapidly shifted from experiment to dealing with a large number of visitors.

Yang Rui thus separated from the laboratory, but Houston and others are still struggling beside the PCR machine. The results of DNA identification should be used in the judicial process, especially in the initial stage. Human errors should be avoided as far as possible. The newly trained experimenters are far from being able to work freely.

In contrast, Yang Rui spends more time dealing with visitors, which is much easier, but Houston and others are still embarrassed.

"You originally came to Sweden for investigation, but it turned out to be a busy job. I'm sorry." Houston mentioned it more than once. It's a big deal in Swedish culture to make trouble for others.

"I'm willing to let PCR work, but I can't do anything to spend some time." Yang Rui couldn't be more than happy. If other Nobel Prize scholars want to invite Swedish scientists to visit their laboratories, they will have to spend a lot of effort, and the hospitality is even more wasteful - not only in terms of cost, but also in terms of time.

Yang Rui is simply not good at this time. The PCR laboratory is placed in the Stockholm police station. Visitors are first screened by the police station. Because the PCR laboratory is jointly run by Stockholm University, they are also screened by Stockholm University. In the end, there are very few minions left.

In the process of Nobel prize selection, there are three steps. The first step is nomination. In addition to professors from six universities in Sweden, there are also many foreign universities and Nobel Prize winners. In this step, it is international.But from the second step, it's purely Swedish.

The second step is for the Nobel Committee to screen the nominated scientists. This five member committee is basically able to decide the majority of the Nobel Prize. However, the real decision-making power lies in the hands of hundreds of judges, who are also Swedish scientists and represent the final decision. In history, many of the decisions made by the five member committee have been beaten back by the review committee. In fact, almost every year, one or more decisions have to be torn.

The five member committee competes for a name, and the appraisal committee calls back. The five member committee competes for another name, and the appraisal committee calls back.

No matter how many times these two steps cycle, it is the Swedish scientists who make the decision.

This is the biggest legacy that Nobel left to the Swedes. The operation mode of Nobel prize also makes Swedish scientists always enjoy a privileged position in the top scientific circles in the world.

Just like now, Yang Rui has to patiently introduce his PCR laboratory to the visiting Swedish scientists. Instead, he is an American. Let's pee by ourselves. I don't care about you.

Scientists who have been famous for a long time, or who have been candidates for Nobel prizes for many times, often need to think more about how to face Swedish scientists.

Because he is young and a news figure, Yang Rui has less scruples.

As a matter of fact, he didn't need too much operation, so he was in the PCR laboratory. Naturally, there were countless visitors.

When Houston saw this scene, he was grateful. He knew too much about the precious time of top scientists, and watched Yang Rui fall into the craze of receiving visitors. He said anxiously: "Mr. Yang Rui, why don't we find more researchers, so as not to delay your work."

Yang Rui thought that this is my business, and said: "there are too many jobs now. You can find more researchers, if you can be busy."

He would like to reduce a certain number of reception times. Anyway, he has seen enough people.

Houston was grateful and went to school to recruit.

However, without waiting for new researchers to be fully familiar with the work, DNA identification work suddenly increased.

"What's going on these days?" Yang Rui, Houston and others are puzzled.

Sherwood is just a simple explanation: "we started to fight against the gang."

Yang Rui and Houston were stunned.

Naturally, there are many homicide cases in the hands of gangsters, but there was always less evidence before. The sudden appearance of DNA solved a lot of problems.

Sweden's action has inevitably attracted the attention of more countries.

Italy, the United States and other countries that are deeply plagued by gangs have to turn their attention to Sweden.

The concept of golden hour has become popular.

Yang Rui's reputation, however, spread to some strange places.
