How to protect rights when it is wrongly zoned and property monitoring is unclear?

Whoever advocates the proof, if the other party's evidence is not enough to prove that you scratched his car, you are not responsible in the public security organ or the court. And you don't need to provide evidence to prove your innocence. The first point is an unwarranted problem, which should be the concern of the other party. If you don't take a picture, you are innocent if you don't take a clear picture. The second question, when the other party has no evidence to prove that you are rowing, you can ask him to stop slandering and eliminate the influence. You can also directly sue for infringement of the right of reputation to achieve the purpose of appeal.
