No, seriously - journalism is not about digging until you find some kind of underlying "fact", there simply isn't time and what you're asking for could potentially be an extraordinary amount of work; journalism is about reporting what the reporter sees and what people tell them. Obviously it's incumbent on them to evaluate their sources, but not usually to write next to the sources' words the journalist's own opinion of the situation.
You can usually see this structure in reporting, where sources will be either named or given an anon descriptor (here "a friend").
"The Iraqi information minister says that Iraq has not been invaded": this is accurate journalism if he really did say that.
"Iraq has not been invaded" (no source) : not accurate journalism.
"The jews are responsible for funding the invasion of Iraq" : fake news.
