If a guy was shooting at me from a neighbor’s back yard, he is putting my life in immediate jeopardy and I would be justified in shooting him.
If a guy is in a neighbor’s back yard and I shoot him while he is unarmed, regardless of what he did in my house - I go to jail for murder or manslaughter.
not exactly the law in my state ... if I witness my neighbor’s home being robbed and I consider the person robbing my neighbors home a threat then is permissible to stop that person under the law in my state. Don’t know the law of your state and that law may not exist in your state but in mine ... one best not be stupid and let me see them in my neighbor’s home unlawfully.
