I have no idea who Bob Owens is, but it seems to me that he has made a couple of assumptions that aren't based on any evidence that has been yet provided. First - we might expect that Finicum was told multiple times to put his hands up as Owens states, but without audio or corroborating witness statements, we don't know. Second - I don't know how he knows that the officer in the trees is left-handed and shooting (presumably a handgun) strong hand only. When I look at that, it seems just as likely to be a right-handed shooter with a carbine. Does he have other info to go on for this?
But that's all nit-picking. I'm otherwise seeing what he's seeing.
It will be interesting to see if autopsy and other evidence is made public any sooner than that from the Council, Idaho fiasco.
