It is very difficult to discern what the "truth" is in a situation like Syria.  Comments like "the fog of war" and "the first victim in a war is the truth" come to mind. Clearly the participants can't be relied on to supply much unbiased information and so you need to rely on those who "report" on the event. What you want is reporting that is not contaminated by opinion and is as accurate as is humanly possible. Much of what is written or said about Syria, by so-called reporters in mainstream media, is far from useful as it is loaded with emotionalism and personal opinions that are based on questionable sources. In general, as with this piece, it is just bad journalism.
