    Although it is just a feeling, for criminals, criminal intuition is actually very important.

    Although this is a mysterious and mysterious feeling, it is the feedback brought to them by the accumulation of experience.

    ¡°And after watching the video, Karasawa, Officer Megure and others made the same judgment.

    There must be something wrong with this guy Daida Uno.

    Generally speaking, even people with no problems will feel panic and anxiety when they enter the interrogation room and face suspicion.

    But the other party didn¡¯t feel this way at all, only a feeling of superiority.

    It¡¯s a bit like a player playing a game. No matter how powerful the monster in the game is, you know that it can¡¯t jump out of the screen and hurt you.

    So you can play crazy and play with the characters in the game and become the "fourth natural disaster" without any scruples.

    This is expressed in the other party¡¯s demeanor, tone, and even every move.

    One detail in particular made Tang Ze even more certain that there was something wrong with the other party.

    When Miwako Sato opened the door to the interrogation room, Uno Daidai stretched out his hand to look at the time, and then showed a calm smile.

    ?Then, after Officer Memu got the news about the delivery man, he told him that he could leave.

    That gesture made it seem like he already knew the answer in advance.

    ¡°If he was not a prisoner, then he should not know the time of Xiaoji Xiangyu¡¯s death.

    Even if he did meet the deliveryman at 9:10, this should not give him confidence.

    But where does this confidence come from?

    This may be the key to the case.

    But unfortunately, all Tang Ze watched was the video recording, and he did not have the opportunity to communicate with the other party to test it out.

    In the video, after Officer Megure signaled that the other party could leave, Daida Uno stood up and straightened his suit.

    "I learned the estimated time of death through autopsy. Sure enough, the power of science is great."

    Before leaving, Daida Uno looked at everyone and said with a smile: "You people, don't always doubt others without basis.

    We should make more use of the power of science so that we can find out things clearly.  "

    Before leaving, Daida Uno looked at the three silent people in the interrogation room and smiled smugly, then opened the door and prepared to leave.

    "Wait a moment!"

    After hearing what Daida Uno said, he seemed to be reminded, but Takagi on the side suddenly stopped him, "If you say so, can I delay you for a while longer?"

    "What? Is there anything else?" Daida Uno stopped and turned around and asked.

    "We would like to ask you to cooperate with the lie detector test." Takagi looked at Daida Uno and said solemnly: "Since you said you are not the murderer, you naturally don't feel guilty, right?"

    "The method of provoking generals? There is no need to use this method. If you feel at ease this way, I will cooperate with you."

    Daida Uno spread his hands and said with a smile: "Anyway, I don't have any regrets. After taking the test, you shouldn't harass me anymore, right?"

    "Of course." Officer Mumu said solemnly.

    The video ended here, and soon Takagi came over and called up another video for him.

    This video is from another room, which is specially equipped with polygraphs. It is a newly opened department of the Metropolitan Police Department.

    Soon, a member of the forensics department came to the room. After some exchanges with the other party, Daidai Uno was asked to put on the lie detector.

    The lie detectors these days are still very simple. The instrument is placed on a table, and then one side of the sensor is tied to the other person's chest and fingers.

    As mentioned before, the lie detector detects based on breathing, blood pressure and pulse, as well as hot and cold changes in the skin.

    Especially the skin resistance indicated by the red line will change significantly.

    This red line is really a red line. The current polygraph test shows fluctuations not from the electronic screen, but from the scrolling paper with drawn lines on it.

    Of course, as simple as it is simple, the function is still the same, and the pointer can also change according to the skin resistance.

    After the instrument was put on, the pre-inspection started in the video, which was the test with playing cards mentioned earlier.

    In the video, Daida Uno still cooperated with the supervisors¡¯ questions and began to deny it one by one.

    And when it comes to whether the poker card "6" is the card he saw, and the other party answers "no", there will be no fluctuation before.?? actually passed the polygraph test.

    This made the people above worry.

    ¡°It¡¯s okay if the other party is indeed not the murderer. If he is the murderer, then maybe the other party has mastered some means to avoid the polygraph test.

    If there is really a way to block polygraph testing, then the problem will be huge.

    If this problem is discovered after large-scale use, countless previous cases may be wrongly determined.

    So this impact is absolutely huge and cannot be ignored.

    If there is even the slightest possibility, then Tang Ze¡¯s decision will be cut off without mercy.

    Even if convenience is lost, at least there will be no problems with the operation of the Metropolitan Police Department.

    And once it is discovered that the other party has indeed blocked the lie detector, it will prove that the "lie detector" has become a thing of the past.

    The so-called science is like this. The continuous upgrading of technology will make some existing technologies obsolete.

    ¡°Checks and balances and being checked and balanced, this has always been the case in the development of science and technology.

    ¡°But Tang Ze feels that even if this situation occurs in the future, at least it is not the current case.

    There is definitely something wrong with that guy!

    He thought that if there was no problem with the instrument, it would prove his innocence?

    It can only be said that the professional habits of scientific researchers make him a bit "arrogant".

    ?Perhaps this will be the case in other professions, but it definitely does not include the criminal profession.

    Their work is full of lies and deception, and the enemies they face are trying every means and trick to get away with it.

    It is impossible to dispel their suspicions with just an instrument test.

    Even when Tang Ze implemented this policy, he said that polygraphs can only be used as auxiliary devices and cannot be brand new at all.

    The purpose is to prevent inaccurate things from happening. The upper-level bosses also know this, and the initial positioning was indeed to use it as an auxiliary tool.

    This time, we paid more attention to it because we were afraid that the other party would have a way to evade the polygraph.

    If countermeasures have emerged, there will be no need for large-scale use of polygraphs.

    To put it simply, the above can tolerate the error rate, which is inevitable, but it cannot tolerate the method of cracking the instrument.

    This is conceptually different.

    When an auxiliary tool can significantly distort the reference, there is no need to exist.

    It is precisely because of the different nature that Hiroshi Saito quickly called Karasawa to inform him of the seriousness of the matter.

    "This is the situation." After Tangze read the information and video, Officer Megure said: "We can't confirm whether there is any problem with the other party now.

    ¡°But the polygraph did show that he didn¡¯t know the details of the murder¡±

    "The case is now at a deadlock." Takagi on the side also sighed: "Our investigation can't find anything good about the other party, and his alibi is also perfect."

    "Just because you don't know how the murder happened, doesn't mean there's no problem."

    Tang Ze said in a deep voice: "Generally speaking, even people who have nothing to do with the case will be a little nervous or even suspicious when they undergo this kind of examination for the first time.

    But his performance was too calm. In the video, I found that he had words that hinted at inducing you to use a lie detector on him.  "

    "What!?" Takagi was shocked when he heard this: "Are you saying that we have all fallen into the trap?"

    "Generally speaking, human nature is to seek advantages and avoid disadvantages. Now that you have proven your innocence, there is no need to provoke criminal prosecution, right?"

    Tang Ze said: "Everyone avoids crimes in the office for fear of getting into trouble, but the other party mocked you before leaving. This is obviously not in line with the mentality of a common suspect.

    There are not many fools who can become associate professors. Weighing the pros and cons is something every adult will do.

    In other words, he should have done it for a purpose.  "

    "We should make more use of the power of science, so that we can find out the matter clearly."

    It was these words with provocative and hidden hints that made Takagi think of using a lie detector.

    Tangze even suspected that the other party knew about the Metropolitan Police Department's recent decision to introduce "lie detectors" and then formulated a "trick" based on this decision.

    After all, if the other party does not induce him to take a "lie detector" test, then the police will definitely continue to investigate the other party.

    But now, the lie detector test has also been done.

    If you can¡¯t produce tangible evidence or make breakthrough progress, you won¡¯t even have an excuse to ask the other party to cooperate with you in an ¡°informal search.¡±

    I have tested it in one sentence, and I blocked you to death. There is no room for rotation.  (Remember the website address: www.hlnovel.com)If you can¡¯t produce tangible evidence or make breakthrough progress, you won¡¯t even have an excuse to ask the other party to cooperate with you in an ¡°informal search.¡±
