SNIPPET: "Seems the FBI was concerned about threats - which included a pledge to turn a tax protest into a blood bath - allegedly made by a Twitter user identified as CitizenQuasar. The FBI arrested Daniel Knight Hayden, 52. Hayden’s penultimate tweet at 12:49 AM on April 15 returned to the subject of his martyrdom. “Locked AND loaded for the Oklahoma State Capitol. Let’s see what happens.” The FBI arrested (.pdf) him at his home later that day, according to the U.S. Attorney’s Office in Oklahoma City, which otherwise declined to comment on the case."
