First, there was a “wall” of moms protecting Portland protesters — now there’s a wall of vets doing the same. A group of military veterans joined protesters in the city for the first time Friday night, standing with their hands clasped behind their backs or holding Black Lives Matter signs, according to a New York Times reporter and others from the scene. “Disabled veterans 4 BLM,” one vet’s sign read. “I am an American patriot. Federal troops defend property, but this does give them the right to take away my constitutional freedom,” another sign from a veteran read.
