Huh, it's actually more flagrant than I expected. Assad invited OPCW in, and the OPCW arrived in Damascus on April 14th.
The 105 missile strike took place the previous evening. The people who ordered the missile strikes were not interested in the results of the OPCW investigation
Proofs: OPCW website
Today, the OPCW Technical Secretariat has requested the Syrian Arab Republic to make the necessary arrangements for such a deployment. This has coincided with a request from the Syrian Arab Republic and the Russian Federation to investigate the allegations of chemical weapons use in Douma. The team is preparing to deploy to Syria shortly.
And from the OPCW twitter feed, announcing their arrival in Damascus.
Assad invited the OPCW in, and the West struck before the OPCW could investigate.
Ok FReepers, which side looks guilty?

Excellent point.
