The Zhu Ling poisoning case is one of China's unsolved mysteries, and the suspect involved in it, Sun Wei, has been the focus of public attention. During the interrogation of the case, the police officers who participated in the interrogation claimed that Sun Wei had passed the polygraph test level, and said that only professionally trained people could pass. If this statement is true, it has important implications for our understanding of this case.
If Sun Wei did pass the polygraph test, it shows that her psychological state at the time of the crime was relatively stable, and there was no obvious psychological pressure or nervousness. This somewhat increases the likelihood that she is not a **. A polygraph test does not fully prove her innocence, as some people may still be able to remain calm in the face of a polygraph test, which does not completely rule out the possibility that they are **.
The police claim that only professionally trained people can pass a polygraph test. This means that Sun Wei may have some level of mental quality or skill that allows her to remain calm during the test. This mental quality or skill may include the ability to control emotions, self-regulate, etc. We can't conclude that Sun Wei is or isn't based on this alone.
Other factors also need to be considered, such as other suspects in the Zhu Ling case, evidence, and the specific circumstances at the time of the crime. These factors may also have an impact on judging whether Sun Wei is **.
If what the police officers who participated in the interrogation said was true, that is, Sun Wei passed the polygraph test and said that only professionally trained people could pass, this shows that Sun Wei's psychological state at the time of the crime was relatively stable, and he may have some degree of mental quality or skills. That doesn't quite prove that she's not. A combination of factors needs to be considered to make a judgment.
