From the Boston Herald:
Smith snapped the photo of Scalia flicking his hand under his chin after a Herald reporter asked the conservative jurist his response to people who question his impartiality on matters of church and state.
Smith wouldn’t give up the photo earlier this week but chose to release it when he learned Scalia said his gesture had been incorrectly characterized by the Herald. Smith, who was standing in front of the judge, said the Herald “got the story right.”
While news outlets from across the country sought Smith’s photo yesterday, the archdiocese said there’s no proof that Scalia uttered an obsenity in the church. Smith said Scalia said, “To my critics, I say, ‘Vaffanculo,’ ” while making the gesture. That’s Italian for (expletive) you.
