Michael Simon bars most use of tear gas and pepper-ball munitions at protests after a CNN review finds federal agents repeatedly violated their own rules.CNN reviewed videos that show Border Patrol and Immigration and Customs Enforcement officers firing chemical sprays and pepper balls at protesters' faces, spraying children and journalists, and targeting people who posed no clear threat.Leigh Kunkel, a freelance journalist, suffered serious facial injuries from a pepper ball, and Kaden Rummler lost vision in one eye after being struck by a rubber projectile, while Rafael Veraza said his infant was hospitalized after being sprayed.The pattern links to aggressive deportation goals set by
Stephen Miller and to leadership changes in the Department of Homeland Security after
Kristi Noem's firing and
Markwayne Mullin's appointment, and investigators including
Mary Moriarty and courts are pressing limits on
ICE tactics.
