1. Collecting evidence: First of all, you need to collect evidence that can prove that the public security organs violated the criminal procedure law, such as relevant documents, videos, photos, and on-site investigation records.
2. Consult a lawyer: If you are not familiar with the relevant legal procedures and prosecution procedures, I suggest you consult a professional lawyer. Lawyers can help you evaluate the evidence and feasibility of the case and guide your subsequent legal actions.
3. Submit prosecution materials: After the feasibility of prosecution is determined, you can submit a written application for prosecution to the local people's court. Prosecution materials generally include indictment, evidence materials and other relevant legal documents.
4. Acceptance and review: Once you submit the prosecution materials, the court will review the materials and decide whether to accept them. If your application for prosecution is accepted, the court will arrange a trial.
5. Trial in court: Trial in court is a legal procedure after you file a lawsuit. During the trial, the court will listen to the statements and debates of both parties and make a judgment according to the evidence and legal provisions.
Please note that suing public security organs or other government organs is a complex legal act and must comply with relevant legal procedures and requirements. It is recommended that you consult a professional lawyer before the above steps to ensure that your rights and interests are properly safeguarded.
