A white supremacist blogger was arrested at his New Jersey home Wednesday and charged with threatening to assault or murder three Chicago-based judges who refused to overturn local ordinances banning handguns.

Hal Turner, 47, a former Internet radio talk show host, was taken into custody by FBI agents who went to his North Bergen home with a search warrant, according to the U.S. attorney's office.

Prosecutors quoted a Turner Internet posting as saying: "Let me be the first to say this plainly: These judges deserve to be killed."

The posting included a map showing the Everett Dirksen Federal Courthouse, where the three judges are based. It said a map showing the judges' homes would later be added.

The posting also referred to the murder of the mother and husband of Chicago-based federal Judge Joan Humphrey Lefkow in February 2005 — a crime that sent shock waves across the nation.

"Apparently, the 7th U.S. Circuit Court didn't get the hint after those killings," the posting said. "It appears another lesson is needed."

U.S. Attorney Patrick J. Fitzgerald announced the arrest, stressing the importance federal officials placed on the case.
