Did you read what I wrote?  I did not say that there were journalists of MSM on the ground.  I said that it is being reported by those that are there that it was Assad.  Assad says it wasn't.  That's all I said, and this was in response to Sumtra saying that there was "no way" that Assad was responsible.  

Those are the facts as they are currently and I know enough about the situation to say that more evidence is need to reach a conclusion either way.

If Assad is correct, there should be physical evidence on the ground to show that a chemical warehouse was bombed.  A thorough investigation is required to determine if a war crime occurred (by either side).
