1, simple things, don't ask a lawyer.
2. Your father's "clamoring for attention to exposure today" is not irrational. In fact, sometimes the involvement of the media will make the legal process faster and fairer: the media has the right to supervise the judiciary, and it is a legitimate right to find media exposure, not an illegal act.
3. "Does this prosecution work? How much does it cost? " ：
(1) Whether the prosecution is effective depends on whether your evidence is sufficient and whether the other party has the money to compensate. If the evidence is insufficient, you are not sure to win the case; If you win the case, he has no money for the time being: you can't get the compensation for the time being.
4. Deliberately chop down 9 pigs in your house: if the circumstances are serious, it is a criminal act and is suspected of deliberately destroying other people's property; If the amount of damaged property is not huge and the circumstances are not serious, it is not a crime, but a violation of public security management. He should be detained by the public security or fined, and compensate your family for their losses.
5. Compensation for family members: If the public security mediation fails, you can bring a lawsuit to the court. But if it has constituted a criminal case: it can only be prosecuted by the procuratorate, and your family has no right to prosecute. After the public prosecution, your family can file an incidental civil action to make him pay for the loss.
6. So: Whether your family can sue now depends on whether he has constituted a crime and is treated as a criminal case. Just ask the police.
