I'd like to disagree with that. If your priori are particularly bad then you should expect your estimates to change quickly based on new evidence.
Unless of course, they have a lot more data than they're saying. My chief worry here is that this was a dress rehearsal for how to make a jet disappear. If so, then the media is doing a fantastic job enumerating the mistakes they made so they can refine the technique so down the road they can make it last just enough to ram a bunch of jets into skyscrapers again. Sigh...
