Chapter 299: A Blockbuster! !

This is actually a very simple truth.

After Gao Yang finished speaking, Liu Jie understood!
Those who work in their line of work have a deeper understanding of these, but the difference is whether they are willing to do so.

Whether you are willing to work for your own conscience or for some kind of benefit, what you get is absolutely completely different.

To give a simple example, the murder of Simpson’s wife, which caused a sensation abroad and even caused a sensation in the world, was acquitted in the end. Americans would feel very sorry, but most of them supported this result, but the Chinese couldn’t understand it at all. result.

Because of this case, the evidence is solid!
It can be said that if it happened in China, Simpson would definitely be sentenced to death, or even executed immediately.

This is a matter of different systems.

In China, once the police think that someone is a suspect, they can directly detain them and then slowly find evidence, but this situation is not feasible in foreign countries.

What's more, in foreign countries, the police must have a search warrant if they want to search residential buildings. Otherwise, even if any evidence is found in the search, the evidence is illegal and cannot be presented in court.Just like in the Simpson murder case, the police broke into Simpson's home without a search warrant. Although the police found the murder weapon with Simpson's fingerprints, even bloody clothes and other evidence, it was because there was no search warrant. Details, in court, these evidences will be completely judged illegal and useless.The prosecution's illegal collection of evidence was the most important reason for the final failure of the prosecution in this case.

But if it is in China, if the police directly break into the suspect's home in an emergency and find evidence that the suspect has not had time to destroy, then it is definitely a great achievement and the key to solving the case.

This is the difference.This is actually the same concept as the previous argument of proving innocence and proving guilty.

If it is allowed for the police to obtain evidence illegally, then who can guarantee that the police will not deliberately produce false evidence to prove the suspect's guilt in order to solve the case?
Liu Jie took a deep breath and nodded at Gao Yang, "Then do you want to detain Miss Gu?"

Gao Yang looked at Liu Jie, "According to the evidence we have so far, can it prove that she is suspected of committing a major crime?"

After Liu Jie was silent for a while, he still shook his head, "No. Although the recording evidence is very strong, it is true that she did not commit the crime. In other words, we cannot find out when she committed the crime!"

"Then between the fact that there was no time to commit the crime and the strong recording evidence, which side should we rely more on?" Gao Yang asked.

Liu Jie gritted his teeth and was silent for a moment before saying, "The former."

Gao Yang nodded, said nothing more, turned and left.

Liu Jie sighed helplessly, although he was very unwilling, but Gu Yi'an must be released, there is no reason to detain her!
After learning that Gu Yi'an was about to be released, Jin Yan looked at Liu Jie in amazement.

"How can it be released? Didn't it mean that the voiceprint identification results have come out? It is confirmed that the voice in the recording is Gu Yi'an, isn't that considered evidence?" Jin Yan couldn't understand.

Liu Jie was a little helpless, watching Jin Yan repeat what Gao Yang said just now.

Jin Yan still frowned, "However, the recording evidence is so convincing, this is the most solid evidence! As for the time of committing the crime...she must have another way to hide it from the camera surveillance, and Tan Jincheng is her husband , his alibi doesn't count!"

Several other policemen also did not understand.

"Yes, the voiceprint identification is not very accurate. As long as the identification results are consistent, it shows that the recording must belong to the suspect himself! We should use this evidence as the standard, and then find out where the suspect is. Time, how did you commit the crime, isn’t that right?” said another policeman.

"Yes, as long as the result of the voiceprint identification is correct, then there is nothing to doubt, it must be her!"

"That is, even if others can imitate her voice, the voiceprint is unique, and no one can imitate her voiceprint!"

"That's right, that's it..."

A few policemen were discussing. They didn't shy away from it at all and sat on the stool beside them. The well-behaved and quiet little Grace.

At this moment, Grace suddenly spoke, her voice was sweet and crunchy.

"The result of the voiceprint identification may be correct, but it doesn't mean that the recording must belong to Aunt Gu." Grace's voice was not loud, but it was very unique.

So, when she spoke, everyone looked at her.

Grace didn't show any signs of stage fright, and looked at the policemen calmly and seriously: "Voiceprint identification is made by drawing a voiceprint map, and then comparing the features with strong stability in the same sentence, such as resonance frequency and direction and waveform to determine whether the two are consistent and whether they come from the same person."

Such words that even half of normal adults might not be able to understand, coming from such a little girl's mouth, are really as weird as possible.

Grace didn't care about the surprised eyes of those people, she continued: "But for example, as long as you have a large number of voice samples from Aunt Gu, you can draw a very detailed voiceprint map of Aunt Gu. Then use this voice After adjustment, the fingerprint map can imitate the same voice as Aunt Gu, and this imitation not only imitates the tone volume, but also imitates the voiceprint information. So even if you compare, you will only think that the two The voiceprints of the two voice samples are the same! But in fact, one of them was made by someone else, not what Aunt Gu said!"

After this passage, Grace seemed a little tired, took a breath, and then said: "Not only that, your voiceprint identification and comparison must only draw conclusions based on the comparison results of those features with strong stability. , but in fact those features with weak stability are also very important. Features with strong stability are very stable and easy to compare, but this also means that they are easy to be detected and drawn and imitated, while features with weak stability, It means that large changes are difficult to capture, and of course it means that it is difficult to be imitated! Therefore, if the feature comparison with weak stability is also very important."

After saying so many words in one breath, Grace immediately began to gasp for breath.

But Liu Jie, Jin Yan, and the other policemen present were all dumbfounded, looking at this in disbelief... this doll that was less than half their height!

···
Some people may think that the beginning of this chapter is a bit watery, but Qinghu really didn’t deliberately make up the number of words. Qinghu’s book is not a romance novel in the general sense. I want to write something that can make everyone think. ****Of course it’s important. But not all.

We hate criminals in our lives, and we would rather kill a criminal than let a criminal go. But we are indignant because of criminals, and want to let criminals die, but how innocent is that innocent person?Who can be responsible for his innocence?
Recently, a lot of unjust, false and wrongly decided cases have been uncovered, so Qinghu felt a little more emotional and talked nonsense, so don't blame it.
