Outstanding video. Thanks for posting it.
Glad you enjoyed it.
For me, beyond the Monday morning quarterbacking I immediately began while watching the video, I most enjoyed the attitude of Mr. Jackson. "If I'm gonna die I'm taking them with me".
My critique is Mr. Jackson only shooting the man holding the gun once before engaging the other who was not visibly armed. He should have focused his initial volley on the greatest threat IMO. A double tap at minimum, which would require only a fraction of a second to execute, yet would double the blood loss, pain, and chance of an instant stop. When #1 risk is no longer a risk then engage #2 risk.
If they both were equal risk then using Mr. Jacksons sequence would likely aid in survival because it puts both under duress instantly and will likely degrade their shooting ability as well as their ability to think.
