This makes no sense:
I also don't know what to make of "other facts gathered by open sources" so maybe the unnamed official could let us know. But I bet if they had a smoking gun, we would be hearing about that smoking gun. The fact that they are being vague, sounds like it's just a bullshit catchall when they really don't have much else.
The official, in a written statement, said that “based on the reported number of victims, reported symptoms of those who were killed or injured, witness accounts and other facts gathered by open sources, the U.S. intelligence community, and international partners, there is very little doubt at this point that a chemical weapon was used by the Syrian regime against civilians in this incident.”The number of victims and their symptoms cannot tell you who is responsible for an attack. Witness accounts might, but there haven't been any witness accounts in the news other than statements by rebel forces who (obviously) have a clear interest in having the blame go to the Assad regime rather than to the rebels themselves. Maybe there are other witness accounts, but those accounts have not been reported. So lets see them before the Obama administration goes off and does something rash.
