I'll repeat the bit about professionals being trained to avoid and deescalate. That is the point. I think the details of this, and many similar incidents clearly show a lack of attempt to deescalate or avoid. That was the clear argument I made in my post and am re-emphasizing now. This clear trend shows either malicious intent by professionals or amateurs put in a situation they shouldn't have been allowed near and those above them should be held accountable for it.
