Jeremy Salt: I don't think there's any doubt at all that a large number of military, of civilians, have been killed by armed gangs and by defectors.  So, what we actually need to do is to disaggregate these (casualty) figures.  How many people have been killed by the Syrian Army?  How many of them were innocent, entirely innocent?  How many of them were men who picked up arms?  How many civilians have been killed by armed gangs?  And so forth and so on.  You need to break the whole thing down, but these figures are not broken down.
