According to the latest property law, personal property is protected by law. First of all, you should support your behavior of dissuading your family from taking revenge by force, and you should take legal channels. Since judicial reconciliation, we should pay attention to collecting evidence, such as taking photos and recording, and don't evade judicial punishment just because someone in the family is mentally ill. Whether his family's mental illness is proved by medical records, if it is not because his family has violated the relevant provisions in the Regulations on Public Security Punishment, and if there is evidence to prove that he has mental problems, his family has the legal responsibility to take care of it, and the guardian should be responsible for the compensation for the material and mental damage caused by the mental patient. I suggest that you pay compensation for the incidental mental loss when you go through judicial channels. For example, when your parents are older, they go to the hospital to issue a certificate saying that they have some heart or body problems after being scared, and the amount of compensation can be appropriately larger.
Of course, we are all neighbors, but in the end, we still look up and see each other. Personally, I think judicial methods can only solve short-term problems, but can't solve the final problems. In this case, you'd better find a local arbitration commission to let their families feel the serious consequences of breaking the law, such as huge compensation and even criminal responsibility. However, if your family is generous and shows appropriate tolerance when implementing it, it is suggested that they only need to make some promises and apologize. Compensation can be reduced or even avoided. As for the specific problems of their family, you can also consider them. Put yourself in the other's shoes and think about how to solve it. It's best to find a way acceptable to both sides. I hope that the contradictions in the neighborhood will not expand. Now everyone advocates a harmonious society, and everyone is tolerant of each other. I don't think it's been a year or two for my neighbors. Maybe the two families have some memories of getting along well with each other earlier.
