There is a great controversy about the power of the American police. Some people think that the power of American police is very limited, such as the famous "Miranda rule" (that is, the police must inform the suspect of his right to remain silent before arresting him). However, some people cite various cases to point out that in fact, the American police have great power, and they often stop others from making unannounced visits on the street. Because the American police are allergic, you must never "talk nonsense" when dealing with them, otherwise you will be forcibly subdued or shot.

The American police seem to be quite ruthless in law enforcement. They are always searched, handcuffed and even shot. This is because the law enforcement concept of American police is very different from that of the East. In China, the police have to risk their lives to save others. Without this spirit, they can't be competent policemen. However, in the United States, the police ask the police to protect their own safety first. Once the American police feel that they are in danger in the process of law enforcement, they can take preemptive self-defense measures, which is completely in line with the law.
