Conan: Chief of Rice Flower's Science Points

Chapter 169 Geek Theft
On Friday night, Shiraishi and Ayako had dinner together and then watched a movie.

On Saturday and Sunday, Shiraishi worked overtime again and sat in on the "Arrest Technique" course. Just after the training on Saturday, Shiraishi took the opportunity to chat with Murasakibara about the security of the guild hall.

As a result, on Sunday, Shiraishi discovered...

There are quite a few people in the criminal justice class. They didn’t come to class yesterday and they didn’t come today either?
"Huh? Why haven't I seen Minamoto and the others for two days? I haven't seen them for two weeks, and they're skipping training, right?" Shiraishi frowned and confirmed with Murasakibara.

"No, they should have come today, but... it seems like a big case happened in the Criminal Division." Murasakibara explained for them.

Although arrest training is important, it is not possible if there is an important case to handle.

"Important case?" Bai Shi frowned when he heard that - it was definitely not a "murder case". According to the case handling procedures of the Mika Police Station that he had established, homicide cases must be notified to him, the director, as soon as possible.

"It seems like a large-scale theft." Murasakibara didn't know how much the amount was, after all, he was not in charge of the Criminal Division.

Bai Shi nodded when he heard this and became a little more concerned.

After the arrest training, Shiraishi took a shower and went to the Criminal Division...

It's true, the atmosphere in the Criminal Division has changed since Kunikida came.

In fact, criminal police rarely have the opportunity to sit at their workstations, which only accounts for about one-fifth of their working time. Therefore, their desks are usually very messy. Smoking is even more common in the office, which is often filled with smoke.

Now not only is everyone's desk tidy, but the smell of sweat and cigarettes is gone!

There are more and more people smoking in the stairwell, so Yuanwei is investigating recently and even applied to install surveillance cameras...

As soon as Bai Shi came in, he found that there were only a few people there, either writing reports or looking through case files.

"Hello Director!"

After noticing Shiraishi coming, several detectives quickly stood up.

Bai Shi waved his hand and told them to do their own thing. Then he looked at the attendance card and wondered, "Where are they?"

The attendance card will show whether the person is "on duty", "resting" or "out on duty". Now several people with the "on duty" sign are not there.

"Director, they are watching the surveillance in Conference Room No. 2." The head of the Fire Investigation Department, Vulcan, as the highest-ranking person present, answered the director's question.

Shiraishi was also wondering how big the theft case was and why the Akasaka class was also there - there was a theft investigation department in the criminal division of the police station, and normally this kind of thing should not be handled by the violent crime department!

And...does it take so many people to watch a surveillance video?
Since there are surveillance cameras, can't we just issue a wanted warrant?
However, Bai Shi did not question it immediately, but went to Conference Room No. 2 and decided to see the situation first.

When we arrived at the conference room, the head of the theft investigation department, Thief Shan, and several people from the Akasaka class were there...

At this time, several people were staring at the surveillance footage on the projector and didn't even notice Bai Shi coming in.

Shiraishi also saw this...

I don't know how many times this has been replayed, but I saw that the camera was pointed at the interior of the room, and judging from the layout, it should be a second-hand store - a second-hand store, that is, a second-hand store that sells everything and also buys valuable items.

Originally, Bai Shi was wondering, since it was an indoor surveillance camera, it should be able to see the criminal, right?

As a result, only then...

The door of the shop suddenly opened, and then the ashtray on the counter floated up, smashing the display case containing a gold bar, the most valuable treasure of the shop. Then the gold bar and other things inside flew out and fell to a place that could not be seen by the surveillance camera...

"Sure enough, I didn't see anything..." Yuan said helplessly, and then he seemed to notice something and turned around and said, "Ah! Director... Sorry, when we were preparing to go for arrest training today, we happened to find that there was a difficult case in the theft department, so we came over to help!"

The leader of the Bandit Mountain Department rolled his eyes and said, "It's not that necessary..."

Sure enough, although Yuan and the others were tense and determined to come to help, in fact... they also wanted to escape training!
Bai Shi didn't reveal it, and asked directly: "What's going on? Invisible man?"

"No, this is the surveillance feature of this second-hand store being used... The surveillance of this security company focuses on customer screening. In addition to being used for theft prevention at night, it can also screen customers and conduct real-time traffic statistics during the day, just like this..."

Bandit Mountain said as he demonstrated it to Bai Shi.

At this time, the projection cut to the daytime surveillance footage. There were many people shopping in the second-hand store, and it looked very lively. Then, after Bandit Mountain pressed a button, an intelligent analysis of each person was displayed - including gender, age, repurchase rate, and other data!
After pressing it again, a large number of customers, mainly middle-aged women, disappeared...

"That's right. In the screening results, these customers are the type who only look but don't buy. At this time, they can be hidden to help the business operator correctly judge the effective flow of people." This is what Bandit Mountain heard from his boss and the security company, and he is learning and applying it now.

Shiraishi: ... "So... this function is also turned on at night?" Shiraishi suddenly felt that this boss must be mentally retarded.

"No, that's not the case. At night, the anti-theft alarm system is normally used for surveillance. Even if the screening function is turned on, the original surveillance footage should be saved. In principle, when it is displayed, the people who are screened out are replaced with the scenery in the store.

"However, when the theft occurred, the store's surveillance system was hacked. Not only did it start to screen everyone, but there was no record and the alarm function was also turned off," Bandit Shan quickly explained.

"Eh? So..." Shiraishi suddenly felt a headache - how could this be a theft? According to the classification of the Metropolitan Police Department, this should be a smart crime, and it tends to be a cybersecurity crime!
The problem is that the Metropolitan Police Department's "Cyber ​​Crime Countermeasures Department" is still in the process of being established, and the Little Xiaomihua Department simply doesn't have the talent in this area...

Even in the Metropolitan Police Department, this thing is more in short supply than forensic doctors!
And it is not the same type as the "lack" of forensic medicine.

The entire island nation is short of forensic doctors. The Metropolitan Police Department alone cannot change anything. The lack of such special talents is because there are no positions...

Just like Odagiri approved Shiraishi's special talent recruitment quota, but Shiraishi still couldn't use it...

It stands to reason that given Shiraishi's status as a "Todai alumnus", it shouldn't be difficult for him to find talent in network security, but the problem is... with such a small salary, it's hard for people to work for you!
Shiraishi was too embarrassed to ask his juniors at the University of Tokyo about this...

"It doesn't matter! Let's just treat it as a theft in a business without surveillance!" Yuan was quite open-minded and encouraged everyone.

"It's a rare business that has five kilograms of gold bars but doesn't install any surveillance." Daozeishan complained.

"The gold bars in the store are indeed lost, right?" Bai Shi suddenly said at this time.

"Huh? That's right...what's wrong?" asked Thief Shan in confusion.

"Play the surveillance video again, the part where the footage was stolen." Bai Shi said directly.

Just when the display case was broken and the gold bars were scratched out of the picture...

"Stop, it looks like the gold bar here has been moved apart, right?" Bai Shi pointed out.

"Indeed, but no gold bars were found on the ground. They must have been picked up." Daozeishan speculated.

But Bai Shi shook his head and said, "No, look at the second layer of the display case... here."

Bai Shi picked up the infrared pen on the table, pointed at a spot in the display case, and asked Bandit Mountain to reinstall the surveillance camera. This time, with Bai Shi's testimony, everyone could see clearly...

"Huh? The card is gone! That is..." Yuan said immediately.

"It should be the flash card of [Blue-Eyes White Dragon]." Bai Shi's eyesight allowed him to see it clearly.

Because the screening principle of surveillance is to directly cover the image of the person with the background of the store, it does not really make the person transparent, so once something is hidden, it will disappear.

"Huh?" Daozeishan, a middle-aged man, showed a puzzled look at this time.

"A card with collectible value... This is not the point. You will see... the door will soon open again. Well, if we calculate the time, the criminal's more reasonable movement is to smash the display cabinet, then move the things that are in the way, then take the [Blue-Eyes White Dragon] flash card, and then turn around and leave.

"This speculation is more reasonable. Although we cannot rule out the possibility that the other party picked up the gold bars on the ground at a very fast speed, at least if we judge his movements from external objects, he would not have had time to pick up the gold bars." Bai Shi said as a matter of course.

"Indeed, we were also wondering why the gold bars were thrown away... If the target was originally that card..." Yuan also muttered at this time.

"He didn't take the 5-kilogram gold bar, but only took the [Blue-Eyes White Dragon]... Was it Seto Kaiba who stole the things?" Yamada complained in a low voice using the animated character.

"Yamada! Be serious." Akasaka scolded him with a stern face - although the director doesn't care much about these things, please don't complain in front of your leader, okay?

"Also... he only took the [Blue-Eyes White Dragon] and did not touch the other cards next to it, which means this card has special meaning to him!" Yuan also said at this time.

Yamada twitched the corners of his mouth and wanted to complain - the more he talked, the more it sounded like Kaiba Seto!
"Besides...you young people know computers, right? Normally, since you can change the monitoring settings at will, shouldn't you be able to directly shut this thing down or stop it from running?" Akasaka looked at Gen and Yamada at this time.

"I think...right." Yuan and Yamada were obviously not very knowledgeable about computers and could only play games occasionally.

"Geekism." Bai Shi suddenly said at this time.

"Director, what did you say? What..." Bandits Shan and Akasaka didn't quite understand.

"Geekism is a mentality that technical personnel generally have. It manifests itself in their courage to test the rules, and...if they can use 'technology' to achieve something, they will be willing to try it even if it becomes inconvenient. It is more common in the IT industry and...more common among young people." Shiraishi explained.
