What was this murder, if not a one-woman civil war?
>Do you want your neighbors to be able to kill you?
My neighbors are always inherently capable of starting that one-man civil war with me, even when locked inside institutions specifically meant to prevent that.
Indeed, the law in the country we're talking about is very explicit about being able to own the tools to wage that civil war as a direct consequence of this fact.
Hiding from that reality has never worked for any other group; why do you think it's going to work for you?
