That's what a couple of "bad guys with guns" when they walked into a Las Vegas pizza shop this afternoon and murdered two "good guys with guns" -- police officers taking a lunch break. Then they took the cops' gear, walked across the parking lot to Wal-Mart, killed another innocent person -- and then shot themselves to death, thus ending their sick "revolution."

More details later. 

UPDATE 7:56 p.m.: Now confirmed that five are dead, including the two police officers and two shooters. (Thus removing earlier update about "conflicting reports.")
