Killing is OK in some circumstances. Yes you can learn it from a video.

Again, its OK to kill bad guys.

If the situation warrants it, but I'd make damn sure that it did, and even then, I think unless it was an extreme situation, it would be best to think twice about that.
As for learning from a tape...well if thats how you want to learn, knock your socks off. I'll go the better route and learn from a live teacher. Like I said, I don't need a tape, put out by some former SEAL, to show me some 'secret' killing moves. I think that Kenpo can give you that and then some. Besides, if that is all someone is interested in, why not just go out and buy a gun?
