Bai Song never thought that there would be such an unexpected gain.

At that time, almost everyone's energy was focused on the crime scene, and few people would pay attention to the surrounding crowd of onlookers, but now that I think about it, there may still be some problems in so many onlookers.

Even, Bai Song just glanced at it, and saw the figure of the farmer captured today from a few key pictures compiled by Zhao Xinqiao!

This person was indeed at the scene at that time, and the person who followed Bai Song later should have been him.

Calming down, Bai Song analyzed it carefully and pointed to the computer screen: "The person you marked, we caught it today." ”

"Who is he?" Zhao Xinqiao was a little puzzled: "You didn't tell me that you arrested any important people today." ”

"I don't know if he's an important person, but with this video, he's 100 percent problematic. Bai Song continued to look at a few pictures: "How did you find out that there is something wrong with this person?" ”

"The gait and demeanor are not normal. Xinqiao pointed to a few other photos, "You look at the corresponding video, this person is nervous." ”

"Nervous?" Bai Song looked at the video and nodded: "It's true, but if you're nervous, it means that he's really not a key person." That is, the little minion, with him as the breakthrough point, I guess I don't know anything. ”

"Well, look at this guy again. Zhao Xinqiao pointed to the second person, "This person has looked at the person you just mentioned several times, and he is still wearing headphones." ”

Bai Song opened the second set of photos and looked at the video carefully.

After all, mobile phone videos have definition limitations,If you just watch it once,It's impossible to see everyone's state,All these photos,It's cut out of the video,And it's marked with emphasis。

The horizontal angle of view of the human eyes can be seen at 188 degrees, but the angle of concentration is only 25 degrees, and if you stare intently at one point, you can only observe one person in the whole video.

In other words, don't watch this video for more than 20 minutes, but if you want to analyze it carefully, you can watch it for a long time, and Zhao Xinqiao took the trouble to watch it many times before he counted these.

After looking at it carefully for a few minutes, Bai Song found that there was indeed something wrong with this person, he had "inadvertently" looked at the farmer twice, and he was also wearing headphones, and his mouth was also talking, although he couldn't hear what he said, but it was certain that he was not talking to the people around him.

The video is still not clear enough, and if you don't stare at this person carefully, there won't be any receipt.

Bai Song changed his perspective to the farmer again, and he couldn't see whether he was wearing headphones or not.

"Does it help you?" asked Zhao Xinqiao.

"Yes, and it's very big. Bai Song was very grateful, after watching these videos, he was very moved, and stood up and prepared to hug Zhao Xinqiao.

"Get up, go and get busy with your case. Zhao Xinqiao pushed Bai Song away, then turned around and entered the second bedroom, "Don't be too anxious about this matter, I won't think about it." ”

...

Bai Song watched Zhao Xinqiao go next door, and looked at the computer for half a minute.

Do you want to call Wang Liang again to show affection?

I heard that Ma Zhiyuan's sister and Ma Zhiyuan are not the same character, it may be that Ma Zhiyuan dotes on his sister very much, and his sister studies well, but her personality is still a little girl's character, and falling in love almost tires Wang Liang half to death.

Forget it, let's be a human being.

Bai Song thought about it, directly sent the photo of the second person to the mobile phone of the Qin detachment, and then called the Qin detachment to tell about the situation.

"Is this person the superior of the peasants?" asked the Qin detachment.

"The peasant didn't speak from beginning to end, and he said it a few times, as if he was directing the peasant, and every time he finished speaking, the peasant would look at it a few more times and so on. Bai Song explained: "The video is too big, I can't send it from the mailbox, I'll put it in the network disk for a while." ”

"Okay, send it over and we'll study it. The Qin detachment said: "This discovery is very important, maybe this is the key to the case, who found this?"

"Uh, my girlfriend. Bai Song paused for a few seconds, but decided to tell the truth.

"Your girlfriend?" The Qin detachment really didn't expect this time: "Okay, you're a little powerful... I see, uh, keep it secret. ”

The style of painting changed a little, and Bai Song coughed lightly twice, "Don't worry... Eh, Qin detachment, I have one more thing to say. ”

The Qin detachment may have been choked by Bai Song's words just now, and hummed softly, wanting to hear what Bai Song was going to say.

"That's right, the farmer we caught today, his mobile phone is very clean, and he doesn't have headphones, I suspect one thing, they don't use our 2G to 4G network communication, but use their own radio waves to communicate. Bai Song said: "I just suddenly thought that when I was in Tianbei District, I met bald heads and others, and I happened to meet them at night to go to that factory, which is not accidental."

It is likely that these people installed these devices, and while they themselves can control devices such as black radio stations, they can also be used for their own communications, which are almost impossible to detect as long as we do not know in advance.

So, there are some similar equipment in Tianbei District itself, but after I went to the Economic Investigation Corps, they learned my whereabouts and went there to install one temporarily.

This kind of equipment must still be available in Jiuhe District, and I think we can take technical measures to counter it, maybe we can find some illegal channels, and we can find some necessary things in reverse.

What I think is that if we find out, we can monitor it first, and we don't rush to startle the snake. ”

"Okay, you hurry up and send the video. When the Qin detachment heard Bai Song's words, they became serious: "You have a good rest at home, I know about this." ”

After hanging up the phone, Bai Song operated, sent the video and some photos compiled by Zhao Xinqiao to a network disk, and then gave the account password to the Qin detachment, and leaned on the side of the bed.

After thinking about it for a long time, Bai Song couldn't sleep a little, so he moved the binoculars out of the balcony and looked around when he was idle.

Is there someone in the community watching him here as if they were nothing?

Bai Song suddenly became nervous, and now there are still people watching him? And do you know which household his family lives in?

Secretly pointed the telescope at the person, slowly focusing...

Isn't this the old grandson of the second team?

Bai Song looked at it carefully, it was really!

Oh, my God...

Bai Song then looked around with a telescope and found a familiar figure again.

Alas...

This is the collective I love so much...
