Which jurisdiction's law enforcement authority is controlled by the federal government?

Federal agencies are law enforcement organizations that operate under the authority of the federal government. Their jurisdiction encompasses the enforcement of federal laws and regulations across the entire country. These agencies have specific functions, such as investigating federal crimes, enforcing customs and immigration laws, and ensuring national security. Agencies like the Federal Bureau of Investigation (FBI), the Drug Enforcement Administration (DEA), and the Department of Homeland Security (DHS) exemplify the types of federal organizations focused on law enforcement under federal jurisdiction.

In contrast, state agencies operate within individual states and enforce state laws, while local agencies focus on municipal or county-level law enforcement. International agencies, although they may work in coordination with federal law enforcement, do not operate under the jurisdiction of U.S. law, as they function globally and across different sovereign nations. This distinction helps clarify the unique role that federal agencies play in maintaining national law enforcement standards and responding to federal legal matters.
