Officers have failed to provide sufficient warnings as required before using force and have used force disproportionate to the danger faced, he said. Trained and experienced federal officers should be able to protect the ICE building without using such force, even in the “heat of volatile protests,” he said. Dickinson said he was among those who sat in the driveway of the ICE building on Jan. 19. He said he was sitting second from the gate when federal officers suddenly fired pepper balls through the barred gate. She argued that the federal officers’ force is chilling protesters’ First Amendment rights and poses an immediate risk of harm to them and bystanders.
