Recording of the radio communications of the commander of the Syrian armed forces, Brigadier General Suheil Al-Hassan, giving the order to attack the city of Duma “with all available means and all types of weapons” is already online. That was the order that was followed by a Syrian Air Force helicopter dropping the nerve gas two days ago!

Haven't found the actual recording yet. This was on Facebook from Amir.

So some hearsay posted on Facebook is evidence?

You're kidding right? I am sure you can finds dozens of postings on Facebook, Twitter, and even mainstream outlets of all kinds of theories about what happened. None of them are evidence of what really happened.
