I'm going to hug my family a little tighter tonight. 46th school shooting of the year, and the 47th also happening in Colorado.
(Very, very graphic death) https://x.com/_geopolitic_/status/1965851790714482943 (not safe for life / NSFL)
[Graphic description] What kind of gun could that have been? Incredible amount of kinetic energy—you can actually see a hydraulic pressure wave oscillating through his entire chest. This was obviously fatal, if anyone wasn't sure. Probably died instantly, given the neurological "fencing" response (suggests spinal cord was hit—never mind the artery, he was already dead).
A lot of the damage of a bullet is this concussive damage, not the piercing damage. Hollywood has been lying to you (apparently real gun experts hate the movie “shoulder shot” because there’s a lot of things to damage there, especially once you take the concussive force into consideration).
For those who are on the fence, don’t watch it. I just did and I regret it. Suffice it to say that the blood loss alone will be critical condition at the very best.
Could you expand on this? What does neurological "fencing" response mean, and what in the video indicates this is it?

I mean, people are watching (I haven't) and wishing they hadn't.
He was shot in the neck because the shooter is amateur and didn't account for the bullet drop on this distance.
Ironically the prevalence of AR-15s has made people underestimate the amount of power and damage that most deer hunting rifles possess. 5.56 is like the bare minimum you can get away with to reliably disable or mortally wound a human or similarly sized animal, which is why the military used it because it saves weight so soldiers can carry more of it even if they have to hike 20 miles to their objective. Most hunting rifles are serious overkill for killing their target because hunters want instant take downs, not an animal that is able to stand up and get an adrenaline boost and sprint away if even for just 15 seconds into the brush because the shot was a half inch to the left. .30_06, a common deer round and used in the M1 Garand of WWII, is just under twice the muzzle energy of 5.56.
There are many different kinds of ammunition design. Some pierce and punch holes, some fragment and tumble, some balloon and expand, some cause large tears and cavities.
Ballistic science is actually a fairly complicated rabbit hole
But I also recognize it can possibly trigger anxiety (overwhelming, in some cases) for some folks, even if you don't realize that it might (until it's too late).
Not suggesting we turn to censorship. But at the same time, I guess I'm mostly looking out for folks that may not be aware of the effects it could possibly have (e.g. naive and/or not taking warnings seriously enough).
Also: smaller assault rounds like 5.56 can in fact do more damage than larger ones in some case because of its tendency to bounce around in the body.
But also, no, the smaller rounds don't have a "tendency to bounce around in the body". It sounds like you're referring to the phenomenon known as tumbling, where the wound track ends up being curved because the bullet loses stability as it hits. This happens because bullets are heavier at the base and thus unstable; while in air, they are stabilized by rotation imparted on them by the rifling, but once they hit anything dense (like, well, human body) it would take a lot more spinning to keep them stable, so all bullets do that. It does not involve any bouncing, however.
Light and fast bullets like 5.56 are particularly unstable and will do it faster, though. But even then, for 5.56, the primary damage mechanism is from bullet fragmentation: between the bullet being fairly long and thin, and high velocity of impact, the bullet literally gets torn apart, but the resulting pieces still retain most of kinetic energy. Except now, each piece, being irregular, travels on its own random trajectory, creating numerous small wound channels in strong proximity, which then collapse into one large wound cavity. But, again, this is mostly a function of bullet velocity and construction (e.g. presence or absence of cannelure), not caliber as such.
But regardless, the specific mechanism of his death is clear. He died by gunshot.
This is very different than bleeding from, say, a major artery in a leg. In that case the issue isn't loss of piping to the brain, it's losing blood until the total blood volume in the body isn't sufficient to maintain a workable blood pressure, and yes that can take multiple minutes before a person loses consciousness.

That snippet is referring to the circle of Willis*, which is a "backup" circuit that can route around a blockage to the blood flow to the brain on one side.
The thing is the circle of Willis is tiny and near vestigial (there is a substantial fraction of the population where it doesn't even make a full circuit), whereas the carotid is one of the largest blood vessels in the body. The circle of Willis isn't nearly large enough to reroute all that flow. It has to be made bigger over time through a process called collateralization, and that's a process that happens over months to years, not minutes or seconds.
In short, the circle of Willis will save you from years of high cholesterol that lead to a huge cholesterol plaque completely blocking off one of your carotids. It won't save you from your carotid being severed by a bullet.
*And some other tinier vessels, but mainly the circle of Willis
