oh wow, good one.
I have to agree with you, except my wife carries a Glock 23. But following the question and scenario back her into a corner and protect. Beauty of 50-1 is how many want to be the first 16 before my mag change? A rush of a violent mob again creates an articulable threat and fear (16-3-21 again) if you verbally command them to stay back... Your covered. If they are just making a run on MD2020 of the local Korean corner store (does that cross a line?) and do not approach nor threaten us... We will watch the show.
you can't use lethal force to protect property.
Nail on the head IMO
