Four U.S. Army soldiers based in Georgia are accused of killing two people, CNN informs. Beyond that, a Georgia prosecutor and federal authorities are offering differing responses to a possible plot by the group to overthrow the government and assassinate President Barack Obama. “As far as the evidence has shown, the motive for the murders was the overthrow of the government,” District Attorney Tom Durden said. A law enforcement official said the men had legally purchased at least 18 rifles and handguns in Washington and Georgia. The official said uncompleted pipe bombs were also found, and were comprised of store-bought materials. No sophisticated military grade-explosives were involved in their construction.
