I’ve assumed that we’re all looking at the same video footage (with or without the distracting over-narrative of the original post). But maybe not.
I saw an immediate stop upon contact with a live occupant in the house. I saw an immediate switch from flashlight to weapon and withdrawal to concealment upon recognition that the occupant was armed. I saw that followed by continuous efforts to verbally connect with and de-escalate the advancing armed subject, interspersed with a rapid sequence of radio calls to provide, supplement, and step up reinforcement, while continually withdrawing to cover until stalled by a dead end. Meanwhile, the armed occupant continues to advance, with vague aggressive mutterings and demands, until reaching the doorway at the stuck deputy. In the version I watched, the subject was fogged over at the actual moment of shooting. Based on the muzzle intermittently peeking around the corner of the doorway, I have presumed that the deputy was ultimately faced with the occupant presenting a handgun at close range — but maybe something else is under the obscured part. I never saw a step of advance from the deputy after the occupant was located, and never heard a word from the deputy which was not de-escalatory in tone and content.
I really don’t get what you mean by “back down, back off, and de-escalate” that this officer did not attempt the entire time following contact with the occupant to the point of shooting.
Back down an open stairwell a couple yards from a threatening armed person? No. That’s potential suicide and/or the shooting would happen sooner, not later. That’s a tactical error I would not support.
Close the door to the retreat room (if there was one), and hope that fairies would come and take this guy peacefully? I think that would be failing a duty to protect. I’d probably accept that decision, but I wouldn’t respect or require it.
Out the window of the retreat room (if there was one), and hope to not be shot while waiting for EMS? Maybe. I would not require that choice without being there.
Retreat right instead of left? That’s a crapshoot in a house partly seen just one time. Maybe there were better retreat options in another direction (secret staircase with an armored and locked door at the upper landing?). I can’t see that requiring some other retreat choice in a maze of halls and doors is reasonable. I expect that a right-handed officer would be inclined to hug a left wall, and retreat to the first turn left into better cover or concealment — and that’s exactly what I observed.
Surrender to the armed threat and hope it all worked out well; or try to grapple a gun by hand or with less-lethal? That officer would be a TV hero, but not a smart one.
I don’t know how this outcome is unfolding now. Maybe given the chance to do it again, the deputy would take the suicide stairs or the 2nd floor window. I hope not.
We can differ in our assessments and conclusions about how this event did or should have unfolded, but I observed no defects in the deputy’s decisions or actions — and I don’t expect SOPs across the land to routinely start sending multiple officers to an unremarkable welfare check; for individual officers to be directed to hold until a “boarding party” is available to execute such a check; nor require uncovered retreat from armed threats. Again, I hope not.
