Well, editing a newspaper is not like hearing a case in a court of law. You very often have certain pieces of information of which you are certain, other pieces of information which are the subject of dispute. You have person A claiming a certain thing, person B denying that that certain thing is true. And then areas of a story where you would like to have information, but you simply don't have it. And even if you have been working on a story all week, the judgment normally has to be made on a Saturday afternoon and the full array of information on which you're going to base that judgment is not normally in your hands until that point.
