The new bit was the video itself. Saying "X happened", and offering "Here is video that demonstrates X happened" are very different things. A video of an event can be of such overwhelming significance that its importance is impossible to calculate.
Not the case for this incident. You don't have to speculate, you can just read the wikipedia page. For instance, a reporter for the Washington Post was able to reconstruct the incident and write a book about it without seeing the video. 'Collateral murder' is much more notable for the Wikileaks editorializing than for its actual news value.

Is that not worrying though: a journalist writing an article, whilst ignoring a reputable source? If there is a verifiable video, shouldn't the journalist view the video (and decide whether it's verifiable or not), and include that in the article? To deliberately ignore a significant piece of evidence is a significant editorial decision.
