Following President Trump's inauguration in January 2025, the U.S. government designated large areas along the southern border as national defense zones, granting the military authority to apprehend undocumented immigrants. Subsequently, federal prosecutors began filing charges for trespassing on military property at an increased rate. An investigation revealed that at least 4,700 immigrants already charged with illegal entry also faced these military trespass charges. A key issue was that many migrants were unaware they were on military land, leading to a high rate (60%) of dropped or dismissed charges. Despite this, prosecutors continued to file these charges, raising concerns about the fairness and legality of the prosecutions, especially given language barriers and inadequate signage. The investigation analyzed federal court data and case records from West Texas and New Mexico.
