The process of globalization has affected the functioning of the U.S. criminal justice system. It should be mentioned that many people, who are suspected of committing crimes against American society, can live in other countries. Therefore, they can be outside the jurisdiction of the United States government. In turn, American law enforcement agencies have to establish close partnerships with the governmental organizations of other states. This cooperation is essential for the detention of suspects and the investigation of criminal cases. Moreover, such international agencies as Interpol play an important role in the identification and detention of people who can be suspected of serious felonies. Thus, one can say that the U.S. criminal justice now has to function at an international level.
Yet, there is another change that should not be overlooked. The U.S. criminal justice has always been based on the idea that a defendant can receive due process, which means that this person can defend his/her rights in court. This is the underlying principle that American law enforcement officers have to follow. However, this situation has changed dramatically within the last decade that was marked by such events as the 9/11 attacks.
At present, the U.S. government is responsible for maintaining prisons like Guantanamo, in which people can be detained for an unlimited period of time without any justification. Overall, the U.S. criminal justice operates in an environment in which there are civic rights of the American people and the human rights of those people who do not have U.S citizenship. So, it is possible to argue that the treatment of people who are suspected of crimes has changed significantly. This is one of the main impacts that should be considered.
