Whether the criminal law can punish Liu Xin depends on the laws of China, because the Japanese prosecutor thinks that Liu Xin is also a victim, and she is innocent, even if she really locked the door and didn't help Jiangge. Because Japanese prosecutors think that Chen Shifeng is actually planning to kill Liu Xin, and if Liu Xin opens the door to welcome him out, he will probably be killed, so they think her behavior is not wrong.
Japanese law will not punish Liu Xin, but what about China? I believe Jiangge's mother will sue Liu Xin in the future! According to the laws of our country, let's infer how likely Jiangge is to be punished.
Evidence 1: knowingly not reporting, delaying the progress of the case.
Allegedly, when Liu Xin made a statement to the Japanese police for the first time, he said that he didn't know who the murderer was and misled the police that it might be some pervert in Japan. This is a lie. First of all, she may have seen Chen Shifeng at the time of the crime. Even if not, she clearly recorded what she said, "The door is locked, don't scold." She and Chen Shifeng are boyfriend and girlfriend. Since she listened to Chen Shifeng's speech, she couldn't distinguish his voice. But she didn't report it when she took a statement. Should she be responsible?
Evidence 2: from destruction? Destroy evidence?
Whether these two points can be qualitative depends on the evidence collected by the Japanese police. Did Liu Xin open the door after fleeing the scene after the murder in Chen Shifeng? Is it true that for Jiangge struggling from the ruins, as long as he holds down the main bleeding point, he can still help the patient buy time to save his life? Obviously, Liu Xin didn't save the girl who stood up for her!
It is said that the door handle of the room is clean, without fingerprints, which is suspicious. Did Liu Xin wipe the fingerprints off the doorknob before the police came? If Jiangge's mother has evidence that Liu Xin did it, then she must bear the criminal responsibility of destroying the evidence!
I hope Jiangge's mother will live strong for her daughter, so that Liu Xin will not only be spurned by public opinion, but also get the punishment she deserves!
