'...If you shoot to kill regardless of the gravity of the attack you will be prosecuted for manslaughter..." Regardless of whether one "shoots to kill" or not, there must be a death involved for a manslaughter charge to be filed. That's why they call it manslaughter. Those shot in this incident here were wounded in their legs. So far the evidence points to a clear case of self defense. And a suspect is considered innocent until proven guilty. Even in America.
