MORE ON THE NEW CIVILITY: Obama fanatic threatens to kill Arpaio.

A “fanatical supporter” of President Barack Obama is the prime suspect in an investigation into an Internet death threat against Maricopa County Sheriff Joe Arpaio.

Adam Eugene Cox, 33, was arrested in Tennessee Friday on an unrelated warrant for assault.

Working with MCSO, deputies in Knoxville, Tenn., served a search warrant and seized evidence from Cox’s home on Friday after an investigation into the death threat came to light in October.

In that threat, Cox stated Arpaio and his family would be killed, according to MCSO. His postings read, in part: “I plan to kill Arpaio first. He will be filled with a thousand bullet holes before the year is out. I promise you this. He won’t [expletive] with Obama. He will be buried 10 feet under and his whole family will be murdered along with him.”

Well, given the President’s extremist, eliminationist rhetoric, this sort of thing was bound to happen, I suppose.
