Why do the police like to get on the police car with the sound of "finished" when they catch bad guys?

Dead cat, how do you know that ta people are going to catch bad guys? There are three main functions of whistling: first, it is reasonable and legal, second, it is legal and unreasonable, and third, it has nothing to do with emergencies: it reminds vehicles and pedestrians on the road to avoid in time and arrive at the scene as soon as possible; It will play a deterrent role in time for criminal suspects to stop their criminal behavior as soon as possible. Don't you understand this deterrent effect? For example, 1 10 command center received an alarm saying that a suspect was robbing and might kill someone, so 1 10 assigned a patrol car to the police. In this case, it is natural for a police car to whistle, in order to let the suspect hear the siren, because as long as the suspect hears the siren, he is likely to be scared or scared away, thus saving a life. If the suspect escapes, he can be arrested afterwards. Although it will be laborious, the cost of arrest is not as important as human life. Of course, the police can sneak up to the suspect to subdue him, but it will waste a lot of time, and the victim may be dead when the suspect is caught. Clear the way: honking the horn to clear the way for the leading motorcade is not much different from the gong clearing way in feudal times, and it is a legal nuisance. Be overbearing: "Uncle NND's car is here, get out of here", nonsense! In addition, during the actual arrest, the horn will definitely not ring, and it is likely that even the police car will not be used. Arrest is not the same as surprise attack. To put it bluntly, a sudden attack means rushing to the emergency room to recover the losses as much as possible. The arrest is carefully planned, the purpose is to hit the target with one blow and never startle the snake.
