Wow. Couple of points come to mind.
- Watching the video in the store, people in the background seem to have no clue what's going on. A guy walking around with a knife (Scott), someone with a camera recording the guy, and in the background it's, "Oh look, I wonder if they have this in my size?"
- Once the knife-wielder fixed on a target outside (the CO), he was fixated on following the guy. I know it's armchair quarterbacking but it seemed like the CO could have gotten Scott away from the crowd (a crowd rarely being a good thing to have around when dealing with a mentally disturbed person).
- Speaking of walking around in Condition White, I wonder if the bald guy wearing a green shirt in front of the store realized what was going on at any point before he basically had to step around the CO to get to the store (he did get fairly agile once he realized he was about arm's length away from a crazy guy with a knife ).
- Hard to tell from the angle, but it did seem that the CO put a number of people at risk when he decided to shoot, although the moment wasn't necessarily his choice.
Interesting video -- thanks for posting.
