In public. Only when I'm personally threatened? If I'm with my wife and she's threatened with bodily harm from an attacker? What if some guy walks into the mall with a rifle and opens fire?
It seems I remember that in OK, it's only in defense of yourself or an immediate family member. One is forbidden from using lethal force with a firearm in defense of a stranger.
Thanks.
If the guy you think you wanna shoot:
1) Has demonstrated in some way the intent to cause you or (be careful here) others severe bodily harm or use lethal force
2) Has the opportunity to perform 1)
3) Has the means to perform 1)
Then you can pull your weapon of self defense and use it in that manner. Remember - you must not have the intent to kill your attacker. Your intent is only to stop him/her from applying lethal force or severe bodily harm to you or yours.
