Hey if you break into my home i will definitely point a gun at “your” head. But then again would i really fire in your back if you just run away? i guess not!
As long you are no danger to me or my family i´m not willing to kill you because i don´t care if law allows me or if it doesn´t. At the end i´m a human beeing and i don´t kill people just because some law might say that i have been correct under the current state of law.
