What the Evidence Shows
Regarding the need for a judicial warrant, ICE officers have authority under Section 287 of the Immigration and Nationality Act to arrest individuals without a judicial warrant because immigration violations are civil matters, not criminal offenses. This means that ICE can arrest people in public places without obtaining a warrant from a judge. However, ICE cannot forcibly enter private homes without either consent or a judicial warrant.
Concerning operations at sensitive locations, ICE follows Department of Homeland Security (DHS) guidelines that generally prohibit enforcement actions at "sensitive locations" such as schools, hospitals, and places of worship. These policies are intended to protect vulnerable populations and maintain community trust. While these guidelines are not absolute legal prohibitions, ICE typically avoids conducting arrests or raids in these places.
Therefore, the statement that "ICE don't need a judicial warrant to make an arrest" is mostly true in the context of public arrests for civil immigration violations. The claim that "ICE don't do operations at schools, churches or hospitals" aligns with DHS policy guidelines restricting enforcement in these sensitive locations, making it mostly true as well.
It is important to note that exceptions or variations can occur depending on specific circumstances or changes in policy directives by the current administration. Nonetheless, the general framework remains consistent as of mid-2025.
