We know
That's why we have guns
.
Exactly this. However, in the current hyper politically correct climate of the UK, Germany and other Western European nations where the North African and Middle Eastern immigrant has been elevated to almost messianic status, shooting and or killing such a person even to save one's own life would surely result in permanent pariah's status and social ex-communication for life. One day soon, the same will be true in our America and no stand your ground or castle doctrine will make much difference. In other words, coming soon, just because we have the ability to defend our lives and the lives our loved ones, the personal cost of doing so could be worse than being mugged, raped or killed by some immigrant whose culture conflicts completely with our own.
