A judge in Oregon on Tuesday temporarily restricted federal officers from using tear gas at protests at the U.S. Immigration and Customs Enforcement building in Portland, just days after agents launched gas at a crowd of demonstrators including young children that local officials described as peaceful.

U.S. District Judge Michael Simon ordered federal officers not to use chemical or projectile munitions on people who pose no imminent threat of physical harm, or who are merely trespassing or refusing to disperse. Simon also limited federal officers from firing munitions at the head, neck or torso “unless the officer is legally justified in using deadly force against that person.”

Simon, whose temporary restraining order is in effect for 14 days, wrote that the nation “is now at a crossroads.”
