Yes it is - no it isn't.

Has the time come when news programmes should come with some sort of health warning?  Recently - and in particular concerning the goings-on in Libya - a lot of speculation and rumour has been presented as fact, only to need a retraction - within hours in some cases.  I appreciate that you can hardly have a news bulletin which starts "There's something going on in Tripoli, but we're not quite sure just what..."  but I think it should be made clear which statements can be substantiated, and which can't.
