The terrible news of a train crash in Germany is covered on tonight's BBC website.  Fair enough.  But a clip filmed by a passenger 'moments after impact', unfortunately, adds absolutely nothing.  The interview with the passenger is great - and would make an excellent soundbite for either TV or radio.  But the footage taken on his mobile phone is meaningless.  You can't make out anything, except that someone seems to be walking through a corridor filming objects close-up.  It's great that we can all potentially be citizen journalists, but just because we've got a phone and happen to film something at the scene of the 'story', doesn't mean it adds value.  The need for editorial discernment is still key.
