The sun was scorching in the sky, the traffic was rolling, the smooth black silk stockings were wandering all over the street, and the long white legs were swinging back and forth.
Jiang Yuan opened his eyes and got up from the hard bed. After waiting for a few seconds, he realized that he was staying in the guest house of the provincial government.
Open the curtains, and there is a lush green plant outside, showing a beautiful picture of being willing to water.
Jiang Yuan stretched out, slowly folded the quilt, and then washed and dressed at an even slower speed.
Two days after arriving in Changyang City to participate in the "Provincial Fingerprint Information Crime Solving Competition", Jiang Yuan already knew that laziness in the morning was the most relaxing moment of the day, and almost the only relaxing moment.
When he comes out of this door, he will hold his chest and head high and maintain a policeman's appearance. As for the office, it is another kind of terrifying casualness.
You can eat as much as you want, drink as much as you like, dress as you like and shout as you like, as long as you can match the casualness of fingerprints.
More than 30 fingerprint inspectors from all over the province gathered together to test the fingerprints. Each person looked at 3,000 fingerprints a day to reach the average level.
Zhu Huanguang, a policeman from Changyang City, is the province's fingerprint king. He sees more than 6,000 fingerprints every day, which is incredible to laymen.
In fact, Zhu Huanguang can read fingerprints for 14 hours a day, averaging 500 fingerprints per hour, which is equivalent to reading 8 fingerprints per minute. Each fingerprint is only observed for about 8 seconds.
With this intensity, he has solved 4 cases from other cities and counties.
According to tradition, or in other words, according to the development law of normal fingerprint solving battles, as time goes by, the number of solved cases must be more and more solved. Because fingerprint experts will gradually increase their familiarity with fingerprints. Later,
More and more cases will be solved.
This is also the reason why fingerprint crime solving battles are constantly promoted.
In the past, fingerprint experts worked independently in various units. From time to time, they also had to do some chores that ordinary colleagues in the unit could do - such as meetings. They could not concentrate on fingerprint comparisons.
The fingerprint battle is different.
During the fingerprint competition, the provincial departments or ministries will provide food, accommodation, round-trip travel expenses, and business trip subsidies. Fingerprint experts from all over the country will be invited to come over. If nothing happens, they will continue to compare fingerprints every day, thus concentrating on accumulating familiarity with fingerprints.
, constantly increasing the probability of solving the case...
The fingerprint experts are also very happy. They are all in their thirties or forties. They sleep in dormitories and eat in canteens. They don’t have to worry about whether their wives are happy or not, whether their children’s homework is done, or whether their parents are arguing.
When quarreling, let alone looking at the boss’s face and colleagues’ thoughts, what you have to face every day are dozens of familiar and unfamiliar faces, hundreds of familiar and unfamiliar fingerprints, and the “ranking list of solved cases” on the wall.
I don't know how comfortable life is.
The reason why there is a time limit for such a mutually beneficial thing is that the provincial department is worried that it will really exhaust the experts.
Of course, the experts' status and case-solving efficiency are also different. For example, Jiang Yuan, on the "ranking list of solved cases" hanging in the office, behind Jiang Yuan's name, the number of solved cases is clearly 0, which is different from that of more than ten others.
Trace inspection together, tied for last place.
However, Jiang Yuan didn't seem to be in a hurry. When he got to the office, he made himself a cup of tea first and then looked around.
Comrade Zhu Huanguang was curling up, and the fingerprints on the computer screen were being brushed off. The female comrade next to him was dotting eye drops for herself. The fat colleague next to him was eating pie, and the screen in front of him was also brushing off fingerprints.
To be honest, the state of this office looks like a college entrance examination study room, the kind for those who are very old.
"Xiao Jiang, you haven't broken zero yet, don't worry?" The uncle at the next station looked over with a smile.
Yesterday, he drank half a box of Jiang Yuan's Chinese food and became irresistible.
Jiang Yuan smiled, turned around and said, "Don't you also have broken zero?"
"I'm used to it." The uncle smiled and said, "Wait for you guys for a while."
"Then I'll hurry up and take two steps." Jiang Yuan finished his daily polite work, turned around and started staring at the screen.
Soon, in the study room... no, in the "Provincial Fingerprint Information Crime Solving Campaign" office, there were only the sounds of typing on the keyboard and mouse.
Jiang Yuan leaned back on the chair and stared at the computer screen, drawing feature points once and looking at many sets of fingerprints.
The fingerprint comparison during the fingerprint competition is completely different from the daily fingerprint comparison. First of all, the fingerprints that can be selected for the fingerprint competition are all selected from various places. There are quantity restrictions, quota restrictions, and entry and exit mechanisms.
To put it simply, we don’t want small cases, things that haven’t settled over time, and things that have been matched multiple times through their own trace inspections.
Therefore, the fingerprints that enter the fingerprint battle are either fingerprints from major cases or difficult fingerprints that are more difficult. Some fingerprints may be one-fifth or even one-sixth of normal fingerprints.
To try to match.
For these difficult fingerprints, it makes no sense to trust the fingerprint matching system.
This kind of thing that ordinary trace inspections can do, there is no need to fill out various report forms and then submit them to experts for processing.
Because of this, when fingerprint experts in the office face difficult fingerprints, the number of candidate fingerprints is directly above 200 or even 300.
It is equivalent to maximizing the role of people, or in other words, the workload of people.
Experts snap photos of fingerprints. In the past, software might have screened them away, but now they have to go through them all again manually, and they have to be the most advanced manpower in the field of trace identification.
But it is not as good as using the software system normally. Most of the backlog cases are impossible to win.
This is also one of the great differences between criminal investigation technology and ordinary technology. Ordinary technology may be more cost-effective and willing to give up some functionality to ensure costs and benefits.
Criminal investigation technology also requires cost and input and output, but at some point, criminal investigation would rather spend tens of thousands of dollars to solve the case regardless of the cost.
This logical conflict has troubled experts from the beginning.
However, this trouble did not affect Jiang Yuan.
He just wanted to simply match the fingerprints, and that's exactly what he did.
At this time, a fingerprint that looked like a parallelogram crossed Jiang Yuan's eyes.
A fingerprint he saw yesterday immediately appeared in Jiang Yuan's mind.
The fingerprints I saw yesterday had a similar parallelogram shape, which is also a very rare fingerprint shape. It was owned by a very rare perverted rapist.
Although, the fingerprint just swiped has no connection with the fingerprint seen yesterday in the software system - it appeared because Jiang Yuan compared a robbery case.
However, Jiang Yuan's first thought was to combine the two together and compare them manually.
The two fingerprints were both very blurry.
Although to the human eye, both have a very obvious parallelogram shape structure, the software system obviously does not think so. Just looking at the grooves, points, and warps inside, the overlap between the two is less than 30%.
But the trend of the lines is the same.
It means that one of the fingerprints is blurred to a critical point and may be severely deformed. At the same time, the same may be true for the other fingerprint.
Jiang Yuan thought and compared. After confirming again and again, he right-clicked the mouse on the right side and made a mark: identified as the same.
From every corner of the office, a loud "ding-dong" sound suddenly sounded.
The experts present who had not turned off the reminder all learned the new news that someone had identified a certain fingerprint as the same.
