Yeah, true. But having been there the previous night, and making good observations the previous night, certainly makes the news report go from pretty strong evidence to almost nothing.

EDIT: Really the important thing I think, is that if your observations are good enough than the evidence from the news report is "worthless", in the sense that you shouldn't pay to find out whether there was a news report that backs up your observations. It's not worth the time it takes to hear it..
