A Boston Herald reporter asked the 70-year-old conservative Roman Catholic if he faces much questioning over impartiality when it comes to issues separating church and state.
"You know what I say to those people?" Scalia replied, making the obscene gesture and explaining "That's Sicilian."
The 20-year veteran of the high court was caught making the gesture by a photographer with The Pilot, the Archdiocese of Boston's newspaper.
"Don't publish that," Scalia told the photographer, the Herald said.
I love how Scalia thinks he gets to order the press around.
