President-elect Donald Trump's plan to use military resources for mass deportations is stirring significant controversy. While some advocates support a focus on deporting undocumented immigrants with criminal records, key Republican figures, including Senator Rand Paul, oppose military involvement, citing legal and ethical concerns. The proposed military deployment raises questions regarding the Posse Comitatus Act, national emergency declarations, and the feasibility of such an operation in terms of resources and human rights implications. Legal experts warn of potential constitutional challenges if this approach is implemented.
