The "fishing law enforcement" in administrative law enforcement should be derived from the "trapping and arresting" in criminal investigation, that is, in order to arrest known criminal suspects while grasping certain evidence, the method of "seduction" is adopted to attract them and make them arrested. Specifically, there are the following situations: First, the trapping object is a criminal suspect; Second, we have mastered some evidence; Third, the facts at the time of entrapment cannot be used as evidence of a crime. However, the purpose of setting traps in criminal investigation is to catch suspects, and traps themselves cannot be evidence. The "fishing" in administrative law enforcement is to induce law-abiding citizens to "break the law" and take the trap as qualitative evidence. This method of obtaining evidence itself is obviously illegal, not to mention the dirty purpose behind it.
Recently, in Minhang District, Shanghai, a "passerby" claimed that he had a stomachache and could not get a taxi, and asked the private car owner to take him to the hospital. Who expected that "passers-by" didn't really have a stomachache, but the owner was recognized as "unlicensed operation" by Minhang District Urban Traffic Administrative Law Enforcement Brigade, and was fined 1 10,000 yuan. Once this matter was reported, it caused widespread concern and doubt.
