Oh, I completely AGREE the neck shot was not excessive in this case!
Hindsight is always 20-20, though and from THAT perspective, a head shot probably would have worked out as well. But in a empty hand vs knife situation, I'd rather err on the side of "excessive" than "not enough" and end up in a pine box.
My point is that it is just something to think about (how hurtful a neck/throat shot can be!) when selecting a technique in a situation that is not quite as dire, say a drunk taking a swing in a bar, for example.
I certainly didn't know a throat strike could be that damaging... The story was definitely insightful!
