ICE sets limits on which officers can stop vehicles

U.S. Immigration and Customs Enforcement is changing its policy on which officers can stop vehicles, and what is required to do when they're stopped, according to sources familiar with the change.

Formal guidance was issued to officers this week, sources said. This comes after several high-profile vehicle stops ended in shootings.

Only those ICE Enforcement and Removal Operations officers who have completed the relevant training may participate in the stops, according to the sources, who said others who aren't properly trained could only offer assistance, but not be the main officer in charge of the stop.
