There is a well known saying to the effect that news stories are used to fill the space between the ads in newspapers, just as tv reports keep the commercials from taking over the air waves. The aim is to come up with a product story that grips the attention of the public, while being as close to the facts as possible. In this case, the various stories are accurate as far as they go. Even the DND factual explanation is included, albeit towards the end and couched in a "DND claims general has stopped beating his wife" manner*. As for retractions or corrections, some of us may remember when wikileaks included an American sitrep that claimed four Canadian troops were killed by friendly fire on 3 September 2006. Immediately many in the media, including one of the most breathless reporters of the "misuse of Challengers" by the CDS story, reported in their best gotcha mode that DND had delberately covered this up. No effort was made to verify the accuracy of one report against a mountain of evidence to the contrary, including the personal experience of at least one Army.ca member. (The FOO Party's log includes the statement "One bomb did not detonate and bounced very close to friendlies.") Instead the outrageous implication was that there had been a huge cover up with the willing participation of all sorts of people, may of whom had lost friends that day. Again, the cover up angle was soon refuted, but to the best of my knowledge, no retraction or clarification was offered.
