Sorry, but police opening fire inside a store and going through a dressing room wall isn't a direct connection to someone defending themselves inside their home accidentally shooting a neighbor in a different house. Not even close really. Kind of a one layer of pressboard compared to 4 or 6 stud walls separated by some distance. I have heard of instances in apartment buildings on rare occasion, but I have never heard of anyone shooting at an intruder in their house, going through all their walls and into another house, going through some more walls and hitting someone. Got any examples of that actually happening ?
