Safe working hypothesis.

I don’t know for sure what evidence we’re dealing with with regard to the alleged Douma chemical incident but I think this^[1] is probably a good starting place for an attempt to make sense of the controversy:

Russian Evidence...

• Forensic Analysis
• Time Lines, Charts
• Earth & Air & H20 Samples
• Deep Interview of Witnesses
• Comparisons to Other Gas Attacks
• Database Analysis of All Probabilities
• Outside Help From Non Biased Agencies
• Logical Deductions from Evidence Found

American Evidence... (Niki Haley & US Gov en masse)

• We Saw It On CNN... !
• We Consulted Colin Powell
• We Read The Trump Tweets
• We Examined The Witches Entrails
