From the Public Editor, Clark Hoyt:
...Did Luttwak cross the line from fair argument to falsehood? Did Times editors fail to adequately check his facts before publishing his article? Did The Times owe readers a contrasting point of view?
I interviewed five Islamic scholars, at five American universities, recommended by a variety of sources as experts in the field. All of them said that Luttwak’s interpretation of Islamic law was wrong...
When writers purport to educate readers about complex matters, and they are arguably wrong, I think The Times cannot label it opinion and let it go at that.
