Paragraphs 43-47 of the Goldstone Executive Summary deal with such incidents. Paragraph 47 may be referring to the incident described in this article. I quote: "The last incident concerns the launch of a bomb on a house resulting in the killing of 22 family members. Israel's position in this case is that there was an "operational error" and that the intended target was a neighbouring house storing weapons. On the basis of its investigation, the Mission expresses significant doubts about the Israeli authorities' account of the incident."// Apparently, the Israeli excuse of "operational error" is no longer used since it was invalidated by Goldstone. At least something is moving.
