(I don’t know of this a question for you or @scriptmedic but I’m hoping you’ll be able to help a little) how effective is the carotid strike actually? Will it actually knock someone out and does it cause brain damage like other knockouts? Is there any way to block against it or lessen the effect? Thank you so much and am very grateful for your blog ))
If I’m bluntly honest, I’m not sure how you could strike the carotid artery in a way that would cut off the flow of blood long enough to render someone unconscious without also killing them.
If you’re deliberately cutting off the flow of blood to the brain by compressing the carotid, that would be a blood choke. As we’ve said before, those can turn lethal with shocking speed. But, I’m not seeing where a strike to the neck would temporarily block the flow of blood long enough to put someone under, without cutting off the flow long enough to kill them.
Assuming you managed to find a way to do this, you’d be dealing with the same problems associated with knocking someone out. You’re cutting off oxygen to the brain and hoping you get a very specific kind of brain damage. I mean, this is the problem here; you’re asking for a way to inflict brain damage without inflicting brain damage.
Even if you did manage to put someone down, as with chokes, you’re talking about the victim being unconscious for a few seconds. So, the value of doing so is fairly limited.
The martial arts I’m aware of that practice strikes to the neck, like Krav Maga, don’t particularly care if the victim survives. They’re more interested in decisively ending a threat and, generally speaking, the dead aren’t much of a threat.
There’s an irony here; you’re describing a kill strike that the victim might be able to accidentally survive. Not, the other way around.
Writers like to use knockouts as a “safe” alternative to killing someone. I’m as guilty of this as anyone. But, the reality is that being knocked unconscious is close enough to killing someone that you really can’t selectively inflict the desired outcome. Similarly, you can’t knock someone out for long periods of time, without inflicting severe brain damage. It can, and does happen, but you can’t choose that result.
Ultimately, this stuff comes from a desire to include, “safe” violence. I’m sorry. There is no such thing. No one who engages in violence has full control over the situation. Some people like to think they do, but they’re deluding themselves. You can have characters who try to do the Batman, “I control all the factors,” but without (some very specifically tuned) superpowers, they really don’t.
Attempting to knock someone out, by any means, means you’re taking on the very real risk that the victim will end up dead. That’s a potential outcome.
