Federal law enforcement is limited to enforcement of the laws of the United States. State and local officers may enforce state or local laws equally. The Federal law enforcement arm is the Federal Bureau of Investigation. On the state and local level, it may be a state police department, a state law enforcement division, a county sheriff, etc. Persons charged with federal crimes are brought to trial in the Federal District Court of that jurisdiction. It is important to note that Federal Courts only have jurisdiction if a federal violation has been alleged. Similarly, state or local violations are tried in the local courts, which vary from state to state. Federal District Courts are uniform throughout the United States; but state and local courts as well as law enforcement arms, vary in title and laws which they enforce.
