We follow how deportation policy has evolved, expanding massively in the aftermaths of World War One and World War Two, while shifting its main targets -- from political radicals and dissidents, to organized criminals, to "undesirable" racial and ethnic groups including Asians and Mexicans. We examine the changing laws and judicial rulings that have carved out an exception for deportation, allowing the government nearly unlimited and unchecked power, with no recourse to the protections of the Bill of Rights -- and finally, we consider how the Trump administration's recent failed attempts to deport supporters of the Palestinian cause might lead to a small crack in the wall sealing the deportation process off from the courts and the Constitution.
