Most folks, upon seeing this video, come to the conclusion that this is a prime example of a victim who has lost situational awareness.
I don't think so. Let us take a look at the body language here.
First, the critter. At the :08 mark, see that side-long glance? His intended victim is awkwardly balanced and his hands will be no use. That's targeting.
At the :10 mark, watch him as he checks the rest of the store for possible Good Samaritans. At :17 he takes a deep steadying breath -- probably unconsciously. This is his body signalling that he has made his decision.
At :21 he rocks away from his victim, storing the most energy possible for a single burst of maximum energy, then accelerates through his victim ...
0:23 -- One shot: Game, Set, Match.
Kind of obvious, isn't it? Folks will say that a blind man could have seen this one coming -- and they're right.
So, how did the victim wind up (metaphorically speaking) on the platter with mint sauce?
I don't think it was a lack of situational awareness. The victim knew the critter was there, and I think the hindbrain of the victim was yelling, "Red Alert!" -- and I'm pretty sure that the victim over-rode his subconscious.
Take another look at the video, except this time we will look at the victim.
See the way the victim is standing? He's standing square on to the counter -- like most people would. However -- and this is Interesting Point #1 -- he keeps his head turned away from the critter. He is doing everything possible to avoid eye-contact with the critter.
Interesting Point #2 -- look at the right arm of the victim. It's firmly planted between himself and the critter. It's a psychological barrier -- a shield -- that he probably doesn't realize he's erecting.
You know what I think? I think the reptile hindbrain of the victim was screaming warnings at him up to the point that the lights went out. And I think he consciously over-rode the signals -- either to avoid the appearance of rudeness, or out of a desire not to appear racist.
The victim walked into the McDonalds, and the critter followed him. Probably starting before they even reached the door, the victim is getting Bad Signals from his instincts.
Victim thinks, "I'm in a lighted area, in plain view of God, the teller and anyone driving by -- what could happen?" He then over thinks the situation, and decides that he's Stereotyping, and That's Just Wrong.
So, at the counter, the victim avoids eye-contact with the critter -- he doesn't want to give offense by appearing arrogant or dominant, so he keeps his face averted.
His hindbrain, on the other paw, doesn't give a flying wheeze about giving insult and moves the arm -- a body-part the conscious isn't concerned with -- into a barrier.
For all the good that it did him.
No, this wasn't a failure of Situational Awareness. The victim was fully aware of the critter and the situation -- he just consciously chose to disregard what his Awareness was telling him.
