why do liberals hate self-defense of all forms?
The guy wasn’t able to defend himself. He’s dead.
This is not a recent liberal leftist law thing - this goes back to English common law with the idea being life belongs to God and the king is the only one who can take a life with cause. So if you kill someone you would have to have that reviewed.
It has been 20 years since I took law classes but that is my recollection.
