Barring exceptional circumstances, a 2001 Supreme Court ruling (decided 5-4) requires the federal government to release these convicts into the U.S. if deportation is not "reasonably foreseeable." The U.S. government has done little to "force other countries to take back their criminals, such as denying visas to their citizens if they wish to travel to the United States." Some of these released individuals have since committed further violent crimes, such as murder, rape, and torturing children.
