I'm sure that over time there are many inaccuracies in news broadcasting and for several reasons. User error is one thing, not checking facts accurately is another, but there are cases where you have to question editorial integrity. During the Balkan war the same footage of people detained in camps was attributed to both sides of the conflict - in one broadcast they were Serbian, in another Bosnian. Same footage. I think this happens when video footage is sold to the media with dubious origins and the media outlet decides to go with it because it's hot.
