Meanwhile, live video from downtown Louisville around 12:30 a.m. showed some protesters behind makeshift wooden barricades, which appeared to be made out of picnic tables spray-painted with the words “You can’t kill us all.” Police in body armor and face shields held batons and lined up around Louisville City Hall. They appeared to fire rubber bullets and deploy tear gas canisters, fogging the air and inducing coughs among the remaining members of the crowd.
