Let's assume that the Zombie Outbreak of 1495 happens again today. You are approached by a horde of shambling, rotting, noseless zombies. They are not dead, not in the clinical sense, they still have a pulse, their bodies, although rotting and infected, are still performing their cellular functions and their brains still have electrical impulses. But they do not have access to higher brain function and approaches people because it's a stimulus. But if they get close to people, they will infect people. So, in this case, is it legal to shoot zombies? Whether in the head or on the body? They are not conscious of what they're doing and can't make decisions on their own, but is self-defense enough justification to shoot them in the head? Would modern law hold you responsible for killing a living human when you shoot dead a zombie?
