First of all, we must know that no one can be found guilty without the judgment of the people's court according to law. The duty of the police is to arrest and interrogate criminal suspects. They can't convict anyone. The premise of conviction is that the perpetrator has committed a criminal act, but "whoring" itself does not constitute a crime, but an illegal act, and the police cannot convict it. Even if the police catch a person on the spot and bring him back, they will record a confession and then detain him and impose a fine in accordance with the regulations on administrative penalties for public security. It is impossible to convict him. Conviction requires a court hearing before a verdict can be made according to law, so the police can't convict the man.
Secondly, although the man was reported, if he did not admit the illegal facts of "whoring" and there was no witness or material evidence to prove it, the police could not punish him according to the Law on Public Security Administration Punishment. This requires the police to investigate and collect evidence, and even punish the man according to law if the proof materials are complete.
Finally, even if the customer is not caught by the police on the spot, it is illegal and will not be able to hide for a while. The man had an illegal "whoring" behavior, and it was a fluke that he was not caught, but he did it. His illegal behavior cannot be written off because he was not caught red-handed, and he will be punished. The whistleblower just made him exposed faster. Not being caught this time doesn't mean that you will be so lucky every time in the future, and you can't escape legal sanctions. Summary: "whoring" cannot be convicted, but it is illegal. The public should report this kind of behavior, assist the police to collect evidence, have zero tolerance for this kind of illegal behavior, and let the offenders be punished as they should.
