The plaintiff has the right to get back his own justice, so he can submit a complaint to the court, which can make the defendant pay the due price, so he has the right to make this suspect a defendant.
The reason why he became a plaintiff is because he can't bear the harm from the defendant, that is, the defendant has already committed a criminal offence against himself, so he should be made to bear the legal responsibility he should bear and pay a share of the guilt for his criminal behavior.
The plaintiff should collect evidence, confirm some testimonies, and let himself know the information of the defendant's crime. He can ask a lawyer to defend himself, and then turn these public criminal evidences into qualification certificates for rights protection.
Defendants are always cunning. He won't bear some of the crimes that the plaintiff gave him, so he will fight for his innocence, so this is a kind of fight in the lawsuit.
If the plaintiff's testimony cannot bring the defendant to justice and the plaintiff's evidence cannot make the defendant bear criminal responsibility, then the case will not be established and will be handed over to the court for a second appeal.
Therefore, the plaintiff must make sure that this character is his defendant, that is, the person who committed the crime against him, so as long as it is determined that he is not a suspect, but has become a real criminal, then it is ok to find evidence directly.
Moreover, the plaintiff's lawyer will not let go of the defendant's various criminal intentions, so he will judge whether he has committed a crime or not according to some testimony of the defendant, and judge what kind of cognition he has hidden the crime.
The law is fair and strict, and he won't let any criminal go, so the plaintiff doesn't need to worry, just let his own evidence make the defendant admit the crime.
