Absolutely, but not firearm or shooter capability. I made no such comments on firearm or capability.
Given that Stacy's story is morphing with time, I will continue to doubt his 'facts' until verified. You get the impression from the video that the first shot hit the guy in the leg and then put 4 more shots in the guy and he could actually see the officer hit the guy twice with 2 shots, which is actually good eye sight at 165 yards. In fact, he said he realized he needed to do something and so he "jumped in there and put that first shot in him..." Funny how the hero left out part of the story less than wonderful. Happens all the time. It may not be intentional at all, or maybe he isn't happy with it. Doesn't matter why, but then we find out that he actually shot a tree with his first shot. (see my link above)
When stories morph, regardless of the intent of the story teller, that usually means that there is some ambiguity about the details. Whatever the reason, there are some problems with the source.
In shooting, golf, and real estate, I have seen where people grossly misestimate distances. Getting the distance wrong by a significant amount of 20% or more isn't uncommon at all. At my range, I have had folks confused 35, 50, and 100 yard targets as 50, 100, and 200 yard targets. Part of the reason for hunters and golfers getting laser range finders is because so many plainly suck or are inconsistent in their abilities to make accurate distance estimates. Countless vehicle accidents are based on incorrect distance estimation, especially relative to speed. "I thought I had enough room {distance} to stop." isn't an uncommon statement.
Try this fun little test with your friends. Ask them how long a football field is. We all know, right? It has the numbers right there! Then ask them how wide it is. If they haven't played or refereed football, they likely will get every answer wrong. They think they know one measurement and will estimate the rest, only they don't know the first measurement. Now ask for the diagonal. If they know geometry, they will work the math in their head if they can based on their known but likely incorrect information. If they don't know geometry, they will give you a true estimate, that will likely be just as wrong.
It is a complex problem that seems easy, but there are several obvious clues that will be misunderstood. This is common in real life estimates of less well known distances, such as estimating the distance to a deer in the woods versus one on the open plains, lighting, amount of time, etc.
Maybe Stacy paced off the distance. Maybe he is good at distance estimation contrary to most folks. He recanted the shot sequence with a revision. Let's see how the ranging and hits hold up.
A football field, BTW, is not 100 yards long. It is 120. Endzones are a part of the playing field. Everyone knows this, but don't include them when speaking of the length of a football field. It is 53.33 yards wide.
