自经历70年代犯罪高峰以来,美国的刑事司法体系发生了非常深刻的变化。警务模式、刑事审判、刑罚执行等各个领域在指导思想,基本理论以及具体的工作方式方面都在发生变化,各项改革措施纷纷出台。替代监禁是上世纪90年代以来美国各州地方法院刑事审判改革的一项比较成功的举措。 Since the peak of the crimes of the 1970s, the criminal justice system of the United States has undergone a very profound change. The various areas such as the mode of police service, criminal trials and the execution of penalties are undergoing changes in their guiding ideology, basic theories and specific working methods, and all the reform measures have been promulgated. Alternative incarceration is a relatively successful move in the criminal trial reform of district courts in the U.S. States since the 1990s.
