Despite being beaten to the obligatory Stig reference by dropzone, I will say there are rules Journalists have to follow, and generally one of them involves not compromising your sources.
When a journalist says “Some say you once kicked a puppy and gave the finger to a basket of kittens…” they often have very good reasons for not saying “Fred Bloggs of 44 Oil Drum Lane says you hate puppies”
Let’s say a journalist is talking to prominent local businessman John Smith, who has been accused of being a Communist by at least one person.
For a start, the “somebody” may not have actually accused Mr Smith of being a Communist. They may have strongly implied it (“Did you know Mr Smith has a copy of Chairman Mao’s Little Red Book on his coffee table, and another one on his desk at work?”) and there could be defamation issues involved from identifying the source, especially if the source denies ever having said anything like that.
Secondly, there may be a lot of somebodies saying the thing in question, in which case the interviewee almost certainly knows at least some of them and who the reporter is referring to when he says “Mr Smith, some say…”
Thirdly, the reporter may be having to ask apparently “dumb” or “obvious” questions to get an “on the record” response to something everyone (or the reporter) knows anyway, but can’t put in themselves. For example, Mr Smith might be well known as a founding member of the Society for Promoting Democracy And Kittens, and the accusations of being a Communist are clearly lies put about by by a business rival with an agenda to slander Mr Smith’s name.
But the journalist isn’t allowed to just say this, so he has to ask Mr Smith if he’s a Communist, which Mr Smith will emphatically deny, meaning the Journalist can then, in good conscience, put something in his story like “Society for Promoting Democracy and Kittens founding member John Smith emphatically denied being a Communist.”
What journalists aren’t allowed to do, however, is simply make up accusations. If the journalist suspects something (based on their research/investigation into the story) but doesn’t have anyone else backing it up on record, I would suggest that “Mr Smith, it would appear…” might be a better way to approach the question.
And now, back to people alternately arguing with or mocking the OP.
