What are the practical challenges and implications of implementing Trump's mass deportation plan?

John Oliver highlights that Trump's mass deportation plan faces enormous logistical and moral challenges. The plan would involve deporting an estimated 13 million people (though Trump's campaign claims 20-25 million), requiring the government to hire between 220,000 to 409,000 new employees and law enforcement officers. The process isn't simply finding people and putting them on planes - it requires arrests, detention, legal processing, and formal removal procedures for millions of individuals who are spread throughout the country and have often lived here for decades. Beyond the practical impossibilities, Oliver emphasizes the moral despicability of mass deportation, arguing that immigrants are human beings who contribute significantly to society, and that such policies would have devastating economic and community impacts.
