Very rarely does it happen, but sometimes a shot through the brain will fail to incapacitate. I've read stories of attackers getting shot THREE times through the brain and still not going down. Is that crazy or what? How is that possible? But it happens.
A shot to the heart though? No way, impossible. If you look at photos of the wound on the attempted murderers chest, there is not a drop of blood. It instantly seized the attempted murderers heart. It passed through the attempted murderers lung and actually lodged in his heart. Perfect shot.
