It was a planned massacre. He should have dialed 911. He didn't. He killed a person after being incapacitated.<quoted text>
Im pretty sure when someone breaks a window and breaks into your home that they have bad intent.
Yes, you should defend yourself if someone comes into your home. You don't lie in wait. From a legal dictionary:
"A person claiming self-defense must prove at trial that the self-defense was justified. Generally a person may use reasonable force when it appears reasonably necessary to prevent an impending injury. A person using force in self-defense should use only so much force as is required to repel the attack. Nondeadly force can be used to repel either a nondeadly attack or a deadly attack. Deadly Force may be used to fend off an attacker who is using deadly force but may not be used to repel an attacker who is not using deadly force."
I guess I was right. Common sense is not so common after all.
