There is no evidence of a chemical attack, no victims and many witnesses testifying to the fact that no attack happened.
It takes more than an amateurish staged video of people pouring water on each other to prove a chemical attack.
It is plenty obvious to anyone with a functioning brain, what the facts are.
White Helmets sponsors did not need or want an investigation, only a pre-text to attack, so they cooked it up, but now it is falling apart for all to see.
