美国是联邦制国家,实行立法权、行政权和司法权三权分立的政治制度,检察权隶属于行政权,检察机关是司法部门的内设机构,总检察长由司法部长兼任。美国的检察机关并不具有法律监督职能,仅仅作为公诉权与侦查权的结合体而存在,主要对警察的刑事侦查过程进行指挥、以公益代表人的身份对刑事犯罪提起公诉。 The United States is a federal state with a political system that separates the three powers of legislative power, executive power and judicial power. Prosecutorial power is vested in the executive power. The procuratorial power is the internal body of the judicial power. The Attorney General is also the minister of justice. The prosecutorial agencies in the United States do not have the function of legal supervision and exist only as a combination of public prosecutorial power and investigative power. They mainly command the criminal investigation process of the police and prosecute criminals as public interest representatives.
