I have no doubt that chemical weapons were used . However there is no conclusive proof who did it . All the news coverage is telling you Assad did it . If you are told something time and time again , you will believe it , and you will be less open to hearing the other side of the story . There is always another side to every story , but we do not hear this . Because then if we were told this other side , we may actually think that this is one big set up , and Assad didn't decide to one day murder his own people .
