Heavily armed civilians with a group known as the Oath Keepers arrive in Ferguson, Mo., early Tuesday, Aug. 11, 2015. The far-right anti-government activists, largely consists of past and present members of the military, first responders and police officers. St. Louis County Police Chief Jon Belmar said the overnight presence of the militia group, wearing camouflage bulletproof vests and openly carrying rifles and pistols on West Florissant Avenue, the hub of marches and protests for the past several days, was "both unnecessary and inflammatory."
