A Las Vegas man, who threatened to blow up to federal judges, will spend the next six years in prison. Clifford Schuett admitted to threatening to kill or cause damage by explosive. Court records show Schuett walked into a U.S. Immigration and Customs Enforcement office in Las Vegas last June and told them he had put explosives in the courtrooms. No explosives were found. This isn’t the first time Schuett’s been in prison for this sort of thing. He was already out on parole for threatening to blow up Nellis Air Force Base.
