Did you see the interview of the paramedics who responded? They said there were rivers of blood; incredible amounts of blood everywhere; a regular slaughter house, to hear them tell it.
I still have a sense that the massacree may have happened; but it was not what we saw on the so-called livestream video.
I think I shared the article you're talking about. I'm still very confused about this whole thing. The videos (both during and after) are ridiculous, clearly casting doubt on the reality of the killings. The statements from the ambulance staff make the carnage seem very real.
This is a standard ploy, reaching back at least until the JFK assassination: in the midst of what appears to be real deaths, create all kinds of confusion and uncertainty so you don't know whom to believe until some authoritative government agency comes along and tells you what "really" happened, and if you think any different you're just a conspiracy nut.
