Castle Doctrine- also known as "Stand your Ground" basically says that if the goblin breaks in to your home, and is chasing you with a tire iron screaming he will beat your brains out, you are not compelled to try to outrun your attacker before defending yourself.
It does not create an open season with no bag limits.
