In October 2004, the BMJ published a personal view by Derek Summerfield in which he expressed his concern at what he saw as systematic violations of the fourth Geneva Convention by the Israeli army in Gaza.1 The article claimed that many of the actions deemed necessary to root out and prevent terrorism had had the foreseeable effect of killing or maiming large numbers of Palestinians, including children, who had played no part in attacks on Israelis. (This issue is, of course, at the heart of worldwide criticisms of Israel’s actions in Gaza last month.) Summerfield supported his arguments with figures published by reputable international organisations, such as the United Nations and Amnesty International.

Summerfield’s article provoked hundreds of responses, about 550 of which the BMJ published as rapid responses.2 Of these, a small proportion were broadly supportive of Summerfield’s article, but most were hostile. Reading them might give the impression of a civilised debate in progress, but the published responses were a skewed sample of what had been received, as abusive and obscene contributions were not posted.
