A more thorough explanation:

Definition: The Federal Rules of Criminal Procedure are the set of rules that govern criminal proceedings in the United States district courts. These rules provide guidance on how criminal cases should be conducted, from the initial arrest to the final appeal. They are abbreviated as Fed. R. Crim. P.

Example: If a person is arrested for a federal crime, the Federal Rules of Criminal Procedure dictate how the case will proceed. The rules cover everything from the defendant's right to an attorney to the procedures for presenting evidence in court.

Explanation: The example illustrates how the Federal Rules of Criminal Procedure are used in a real-life scenario. When someone is arrested for a federal crime, the rules provide a framework for how the case will be handled. This ensures that all parties involved in the case are treated fairly and that the proceedings are conducted in a consistent and transparent manner.
