That was the biggest "question" I was alluding to.
I am waiting to see that reenactment combined with the technical assessment of the weapon.
I am sorry the incident happened but my "spider sense" is tingling that a few pieces of information are missing/questionable.
Yes, I'm wondering if there is some kind of strange incompatibility of the holster and pistol being mated together that causes something to happen when grasped and moved in a certain way - ? Definitely could be a root cause analysis challenge.
