Assaulting a police officer is a serious illegal act. If the act of assaulting a police officer is found and investigated for criminal responsibility, even if the victim's understanding is obtained, the punishment shall not be mitigated. Because knowledge can only be used as a reference for sentencing, it cannot directly decide whether to reduce punishment.
According to the Criminal Law of People's Republic of China (PRC), anyone who violently attacks the people's police who perform their duties according to law shall be sentenced to fixed-term imprisonment of not more than three years, criminal detention or public surveillance. If the perpetrator commits a serious crime or causes serious consequences, he may be sentenced to fixed-term imprisonment of not less than three years but not more than seven years.
Therefore, even if the victim's understanding is obtained, assaulting a police officer may still be punished accordingly.
To sum up, assaulting a police officer is a serious illegal act, and even if the victim's understanding is obtained, the punishment may not be mitigated. According to the provisions of the Criminal Law of People's Republic of China (PRC), those who violently attack the people's police who perform their duties according to law will be punished accordingly.
