That is easy to be trite and say that in the abstract, sitting at your computer. In in certain situations, it might be that obvious. Most situations, however, are not so clear cut. At what point does it shift to 'about' to murder your loved ones? As soon as you see the kid with the machete? What if he is 300 yards away? Do you shoot him? 200 yards? 50? 10? What if he has a gun, but isn't pointing it at you? What if the kid is 3 years old and holding a gun? 5? 2?
