Not Clearly Pro or Con to the question "Should the Government Allow Immigrants Who Are Here Illegally to Become US Citizens?"
"Deporting 11 million people would be a population transfer so large it only has a couple historical precedents, and one of them is Adolf Hitler's. To extract that many people from their communities would require a much larger and more determined effort than Immigration and Customs Enforcement (ICE) is capable of at present...
Sending an amped-up ICE on a mass-deportation mission wouldn’t just be an assault on undocumented people and their families, it would be an attack on American cities, where more than 90 percent of them live. For large municipalities, rigorously enforcing immigration law is unfeasible but also politically unpopular. So-called 'sanctuary cities' have declared their ongoing intention to drag their feet when it comes to cooperating with the Feds. For example, law enforcement in many cities (including New York) selectively complies with ICE requests to hold people in custody on suspicion of being undocumented. ICE can't do their job without local cooperation and the use of these legally questionable detention orders has decreased by more than 70 percent in the last four years."
