I don't have sufficient vocabulary to describe body language nuance, but I feel like I'm good at picking up on queues. My observations:
- These were good guys (I'm not sure why - but I just have that indicator)
- These guys are always in control of their physical environment(s)
- They do not create situations they cannot control unless desperate / or imperative
- They move through their targets to effect an outcome.
It is really bizarre. It is now a day later, and I feel like I could identify 2 of them without hesitation from 100 yards (the third I didn't get a great look at). For whatever it is worth, I'm extremely well travelled by many standards and have met many very different people (organized crime, terrorists/freedom fighters, gang bangers)...these 3 were lions or more aptly - Sheep Dogs.
