From the New York Times op-ed page:
An Op-Ed essay on Tuesday about relief for refugees included the phrase, "In our experience, militant violence is vanishingly rare." Because of a miscommunication, the phrase, which was added by an editor, was published without final approval of the authors.
I actually liked the op-ed piece, which was by the mayors of New York, London, and Paris and which was pro-immigrant. But the worst kind of editing is the kind that inserts factual inaccuracies into an article without the approval of the author, especially when the inaccuracy appears insensitive to terrorist victims. The statistical rarity of the militant violence is little consolation to those killed or maimed by it, or to their friends and family members.
