We all hope that we never have to face a situation where we find the need to defend ourselves or our loved one. I, however, am a firm believer in always being prepared, just in case. Self defense is one of those things that I like to have tucked into my pocket. The nice thing about some of the techniques in this video (that HOPEFULLY shows up below) is that you can disarm the assailant without causing him serious harm. However, one of the things about self defense to learn is this: when someone threatens your life, or the lives of others, be prepared to do whatever it takes to keep them from causing harm. Even if it means seriously hurting or killing them.
I have met some people, have some Christian friends, who say they would never kill an assailant - they know they are going to Heaven, because they have been redeemed. The assailant, however, is not. They want him to have every chance to change that. But my opinion on the matter is this: if he's a simple mugger, he'll have a better chance of getting saved in prison than he will walking off with your money. If he's crossed the line and is trying to kill people, he's made his choice and it is my duty to protect others. Because a killer will not stop with me. He'll keep killing until someone takes him down.
