That still may be considered murder depending what they were holding in their hand and on whether you can prove that they were pointing it at you, prior to your shot. In my view if you shot someone dead then the police would arrest you on suspicion of murder. Once the circumstances were established you may or may not be tried for that or another offence.
This is my view, for my country. Your's has MUCH more liberal gun laws. A liberality j2 obviously appreciates, even if the only one.
