You have one investigator commenting on preliminary evidence, but the actual commission investigating not backing her up. http://www.bbc.co.uk/news/world-middle-east-22424188 http://www.bbc.co.uk/news/world-middle-east-22424188 Carla Del Ponte told Swiss TV that there were "strong, concrete suspicions but not yet incontrovertible proof". Ms Del Ponte did not rule out the possibility that government forces might also have used chemical weapons. Later, the commission stressed that it had "not reached conclusive findings" as to their use by any parties. "As a result, the commission is not in a position to further comment on the allegations at this time," a statement added. The BBC's Imogen Foulkes in Geneva says the statement was terse and shows that the UN was taken by surprise at Ms Del Ponte's remarks.
