True. And that is why you DO NOT make head and spine strikes unless you have every legal right and obligation to simply shoot them.

If you have a knife, I can stop you just as easily by breaking or dislocating your knee and backing up as I can by caving in your skull. Easier, really, becuase your skull is a crash helmet.

Unless you are being paid to kill people or keep the peace, your mission is to keep you and yours alive. That means disable and retreat immediately when you are out and about. If you have a difference of opinion, I'd advise you to keep a good criminal defense and a good civil lawyer on retainer. Becuase you're going to need the latter and probably the former- you've just made a public statement as to your intent to end the life another in a public and recorded forum.

Oops.
