Plus I'd like to point out that even if Assad had done this how would it make sense for the USA, France and the UK to drop bombs on chemical weapons storage sites and thereby risking a massive release of such chemicals aka a chemical weapons attack. Also how is it possible that so shortly after an alleged chemical attack that civilians would be walking, playing etc. at the exact location of said attacks, wouldn't a chemical attack deny civilians the use of this area for some time whilst it has to be decontaminated?

In the meantime there are also reports indicating that civilians who live at Douma are saying that as far as they know it's a fake event. They don't know exactly what happened but they live there and nothing happened to them.
