The American police are divided into three levels: federal, state and town. They are not subordinate to each other and perform their duties. The US Federal Bureau of Investigation is the Federal Bureau of Investigation, which is directly under the jurisdiction of the US Department of Justice, and exercises jurisdiction over related cases in accordance with relevant federal laws and jurisdictional agreements reached between the Federation and the states. The police headquarters works for the state government and is a government employee. Their responsibilities are clearly defined in the agreement between the state and the Federation. Theoretically, they only accept the dispatch of the state government. The name of the FBI is a special agent, and the name of the local police is a policeman.

Second, the clothes are different:

The FBI has no uniform and usually wears a suit; Ordinary policemen have uniforms.

Third, the execution is different:

According to its functions and authorization, the FBI has extensively participated in the investigation of major agents at home and abroad, and its existing investigation authority has exceeded 200 federal crimes.

Police station: a government department that maintains public order and protects people's lives and property. It has administrative power and judicial power.

Extended data:

The FBI is a law enforcement agency under the Federal Bureau of Justice of the Ministry of Justice, and its jurisdiction is:

1 Cross-state crime (such as serial murder) or the crime area is not so clear (such as hijacking).

2 occurred in the United States, involving national security (such as counter-terrorism and counter-intelligence);

Criminal cases involving the federal government, such as anti-corruption

At other times, the police are basically in charge, but many police officers will turn to the FBI for help when they encounter major cases because the latter has more resources and experience. The police are subordinate to the state government, and the United States implements state autonomy. If a criminal case does not involve national or federal security, or is a cross-state crime, the state government has its own judicial and law enforcement sovereignty, and the federal government shall not interfere. (Legislation is another level).
