A federal judge is expected to extend his order restricting the use of tear gas, pepper balls, pepper spray and other munitions by federal officers outside the immigration enforcement building in Portland. The judge, Michael H. Simon, plans to explain the difference between a protester's passive resistance and active resistance to federal officer commands. He declined to rule from the bench, citing new evidence presented during three days of testimony from protesters and freelance journalists. A decision by Monday is expected. Senior Deputy City Attorney Denis Vannier argued that the federal government’s aggressive immigration crackdown has harmed protesters and families participating in peaceful marches and impeded Portland police, who have had to leave the area to escape the tear gas. The Justice Department accused the city and state of having sanctuary laws that prevent police from clearing protesters out of the street in front of the building due to federal vehicles involved in immigration.
