No, because this has happened MANY times before. It happens every day, somewhere, somehow, by someone. Sometimes cops do it, sometimes homeowners, sometimes civilians walking to their car in a dark parking lot. You just don't hear about it everyday, because this case was turned into a circus, by the media, and groups that screamed racism. When I took my ccw class, I was told, if you feel that your life was in eminent danger, you can use deadly force. I was also told, that doesn't mean the other person has to have a gun. I was told, I would be arrested, and I should exercise my right to remain silent, that's what lawyers are for.
I would like to know what constitutes provocation....and what does unarmed have to do with it. I know guys that have studied martial arts for years, they can disarm a man with a gun, they can kill with their bare hands. Their hands ARE weapons. How many times have you heard of a guy accidentally killing another man, because he hit him in the head enough times to cause brain damage? You know it happens.
