Fishing law enforcement, in jurisprudence, the parties have no illegal intention and engage in illegal activities under the temptation of law enforcement officers; In administrative law enforcement, it is similar to "temptation investigation" or "temptation to collect evidence" in criminal investigation. Fishing law enforcement and Britain call it law enforcement entrapment, which is a special concept in the Anglo-American legal system. Like self-defense, it is the reason for the parties to be innocent and exempt.
Of course, the state should punish this kind of behavior. If this kind of behavior is not properly used, it will lead to crime and cause serious social problems. Fishing law enforcement is an inevitable manifestation of political morality corrupting morality. In history, some cases with complicated cases and difficulties in obtaining evidence often adopted the way of fishing law enforcement (called law enforcement trap by Britain and America).
Law enforcement agencies around the world also use similar methods, such as the police playing addicts to buy drugs from drug dealers. However, "entrapment" has strict control requirements and certain preconditions. In other words, this set itself cannot be used as evidence against criminals. Civil law countries also have strict restrictions on this. Japanese law prohibits law enforcers from luring the parties with illegal intentions in order to obtain evidence, because this is an infringement of the personal self-discipline of the parties by state public rights.
Lured by the economic interests of law enforcement (such as rewarding drugs according to quantity, investigating illegal cars, prostitution, gambling, etc. ), our "fishing law enforcement" is likely to flood in administrative law enforcement, criminal investigation and other fields. The problem that happened before us is not the most serious. As far as investigating black cars is concerned.
In March 2008, a driver of a "black car" in Fengxian District of Shanghai was taken into the "law enforcement ambush zone" by the so-called "female investigator" and stabbed the "female investigator" in the car with a knife in front of law enforcement officers (Oriental Morning Post, March 9, 2008). In the past, there were incidents in Shanghai where black car drivers kidnapped so-called "barbs" to vent their anger.
