Stream of thought follows. I am not bashing anyone here, this is how men behave and hash things out.
If it was the kid and it was an 06, it would leave an exit, period. A Vmax or Barnes varmint bullet or similar would have nearly decapitated him. Any medium hunting bullet would exit, full stop.
The video could be an actual strike with an 06. Not saying it isn’t or that one of the other theories about a .22 close up wasn’t or is. It is the theory that a 06 bullet vaporized in a human neck that is ludicrous. Anyone who hunts knows this.
A projectile at that angle would likely have went in the ground.
There was no armor worn by Kirk.
For the love of all that is holy, there wasn’t any armor

can’t believe anyone has to keep saying this.
Now, to me the more pressing questions surround was this kid a lone perpetrator or did he like many others succumb to Manchurian Candidate manipulation
