Mealey's (June 10, 2020, 2:51 PM EDT) -- PORTLAND, Ore. — A federal judge in Oregon on June 9 granted a social justice group’s request for a temporary restraining order barring Portland police from using tear gas as a crowd control measure against peaceful protesters. In ruling on the group’s proposed class action, the judge noted that use of the toxic chemicals violated protesters’ constitutional rights and could exacerbate the spread of COVID-19 (Don’t Shoot Portland, et al. v. City of Portland, No. 20-00917, D. Ore., 2020 U.S. Dist. LEXIS 100801)....
