This may or may not become public information. Was the perp wearing some sort of body armor? Was he a tweeker high on some really special drug?
Was this firearms expert carrying a pop gun?
I’ll go with scenario #1.
a lot of concealed carriers go out the way, to avoid printing of their side arm... such as a small caliber, concealable model... like a 380 or even a 9 mm.
They are successful when they have great shot placement.
I don’t think most perpetrators of terror will go down with but one 9 mm to the chest.
A 45 to the sternum or the ‘golden triangle’ of the head is a different thing than a 9 mm to the torso... but a 45 does not ‘conceal’ as well.
My guess is he had his backup, a smaller caliber piece, and not a service sidearm, and not a 45... but that is just my guess.
He also might have had to fire at a vector that was not as advantageous as at the firing range... to protect those who were beyond the field of fire.
From outside corner to outside corner of eyes, is about 10 centimeters, from the center line of eyes to center line of mouth.. is about 10 centimeters. (3.9 inches)
I suspect when they were asking him about whether he shot to wound or to kill... he correctly answered to “stop the threat”.
If he did center of mass, like many do... it might take a few shots to “stop the threat”... I cannot imagine a 45 to the center of the head that would not stop the threat immediately and permanently.
I am going with the assumption that he was using a short barrel, 9 mm, with multiple shots to the torso... first.
REGARDLESS of what he did... I am very very impressed that it was a permit holder, with training who took the fight to the Christian hating Islamic terrorist... and saved those people’s lives.
THAT is a miracle. God PLACED HIM there at that time and location to save lives!
I think it’s important, particularly in the next several months, for those who are trained and proficient to carry concealed continuously, unless restricted by law...
Even then... I suspect that the terrorist whack jobs, will be out in force at “gun free zones” to try and run up their score between now and the inauguration of president Trump.
