Make it clear that anyone that has to be forcibly deported will not be allowed back into the United States ever again. 44 will cause 440000 to self deport.
Unless the law has changed that is the law. Used to be used as a carrot to get illegals to self deport or agree to deportation without court hearing. The stick was if they were court ordered to deport they could never legally return. When that was enforced they did not clog up the courts because they wanted to try to come back legally.
