The Annual Review of Criminal Procedure (ARCP) is a comprehensive, topic-by-topic summary of federal criminal procedure. The goal of the ARCP—which is written, updated, and edited by members of The Georgetown Law Journal—is to provide readers with an objective, concise, and accurate overview of criminal procedure in the federal courts. The current edition of the ARCP, published in August 2020, represents the forty-ninth year in which the editors and staff of The Georgetown Law Journal have provided this valuable service to the legal community. The ARCP serves as a practical aid to a diverse readership that includes prosecutors and defense attorneys, judges and their law clerks, and prisoners assisting in their own defense or appeal. In conjunction with Georgetown Law, the staff and editors of The Georgetown Law Journal distribute over eleven thousand copies of the ARCP annually.
