The prisoners are in jail on a charge of piracy, alleged to have been committed on one of the ferryboats plying between Washington and Alexandria, on the Potomac river, on tide water. The offense charged is the taking with violence certain property from a passenger on the steamer. The arrest is based upon section 5370 of the Revised Statutes of the United States, which makes robbery or murder in or upon a vessel on tide waters piracy, and fixes upon such a crime the penalty of death. The prisoners are committed to jail here to await indictment in the District of Columbia.
Piracy was originally an offense known only to the admiralty and international law. Murder, robbery, or depredation, committed in a general spirit of hostility to mankind, on the high seas, was called “piracy.” It was cognizable only by the admiralty court. But as pirates often invested havens, bays, rivers, and inlets, and committed like offenses there, it became necessary for the nation whose jurisdiction was thus infested and violated to declare similar acts, though committed on. waters other than the high seas, to be piracy, and to make it cognizable by the local criminal courts. In this way rose the statutory crime of piracy. The constitution of the United States gives to congress power to establish admiralty courts, and to prescribe their jurisdiction. Congress has exercised this power only to the extent of conferring upon the admiralty courts jurisdiction in civil causes arising upon contract and tort. But it has given the admiralty courts no criminal jurisdiction, for the reason that the constitution guaranties a jury trial in criminal prosecutions, and juries are unknown to the admiralty law. Congress has vested criminal jurisdiction in the circuit and district courts of the United States, sitting as courts of common law. It has conferred upon those courts the cognizance of crimes committed on American vessels on the high seas, and of crimes committed on vessels within the havens, bays, and rivers affected by the tides; statutory piracy being among the crimes of which cognizance is thus given to the federal courts. But by the crimes act of 1790 this jurisdiction over certain crimes committed within the tide-water inlets, bays, rivers, etc., was conferred by a section which limited it to such crimes as are committed “out of the jurisdiction of any particular state.” The criminal jurisdiction of the states is exercised by local courts, whose powers do not extend beyond the body of the counties, respectively. But the body of the county has always been held to embrace ail waters that lie within the fauces terras; that is to say, within lines supposed to be drawn from one utmost point of land to am-
