Step-by-step explanation:
The largest law enforcement agency within the governing territory of the United States is the Federal Bureau of Investigation (FBI). It is considered the chief federal law enforcement agency within U.S. national borders and is responsible for investigating and enforcing federal laws. The FBI operates under the Department of Justice and is responsible for a wide range of tasks, including combating terrorism, cybercrime, organized crime, and public corruption.
Another significant law enforcement agency is the Department of Homeland Security (DHS). Although it is not a single agency, it oversees several agencies responsible for protecting the territory of the United States from natural and human threats. This includes agencies such as the U.S. Customs and Border Protection, the Transportation Security Administration, and the Coast Guard.
Lastly, each state in the United States has its own State Police force, which has the authority to enforce statewide laws. They are responsible for maintaining public safety, investigating crimes, and regulating traffic on highways within their respective states.
