I can't say I agree with the guy in the video. He's comparing shooting someone who's broken into your house with the Martin/Zimmerman fiasco in Florida. Seems a difference between night and day to me. If there is anywhere you should be justified in using deadly force if you have to it's in your home.
He also mentions any negative emails or downloads, etc. will come up in court if you dare defend yourself in your home. Why? if they had absolutely nothing to do with the "crime"? If that's the case, then many of us are doomed if we ever use deadly force, because someone will always be able to pull up something to make us look bad.
