New York Times Executive Editor Bill Keller defended the paper's use of documents obtained from Wikileaks that reveal inside correspondents and information related to the Afghanistan War.

In an online chat on the paper's website today, Keller stated:

The Times has no control over WikiLeaks -- where it gets its material, what it releases and in what form. To say that it is an independent organization is a monumental understatement. The decision to post this secret military archive on a Web site accessible to the public was WikiLeaks', not ours. WikiLeaks was going to post the material even if The Times decided to ignore it. We, along with the Guardian newspaper in London and the German magazine Der Spiegel, were offered access to the material for about a month before its release; that was the extent of our connection.

We used that month to study the material, try to assess its value and credibility, weigh it against our own reporters' experience of the war and against other sources, and then tell our readers what it all meant. In doing so, we took great care both to put the information in context and to excise anything that would put lives at risk or jeopardize ongoing military missions.

What does that mean in practice? Obviously we did not disclose the names of Afghans, except for public officials, who have cooperated with the war effort, either in our articles or in the selection of documents we posted on our own Web site. We did not disclose anything that would compromise intelligence-gathering methods. We erred, if at all, on the side of prudence. For example, when a document reported that a certain aircraft left a certain place at a certain time and arrived at another place at a certain time, we omitted those details on the off chance that an enemy could gain some small tactical advantage by knowing the response time of military aircraft.

The administration, while strongly condemning WikiLeaks for making these documents public, did not suggest that The Times should not write about them. On the contrary, in our discussions prior to the publication of our articles, White House officials, while challenging some of the conclusions we drew from the material, thanked us for handling the documents with care, and asked us to urge WikiLeaks to withhold information that could cost lives. We did pass along that message.

We don't discuss our internal editorial and legal deliberations, but the decision to publish was a subject of extensive discussion over the past four weeks, involving a variety of viewpoints, as you would expect for a subject this complex.
