I live in a good neighborhood, although there is no such thing as a crime free neighborhood, I have security doors, and motion lights, I have very good neighbors who watch out for each other, i have security screens, an alarm that was here when I bought the house, that's not monitored anymore, AND I am armed when I am at home, and I am armed when I go out, when i sleep it is in the bed side stand.
If someone assaults me or robs me, it will end badly for them.
