I have lived in a 98% safe community since 1974. Have not had any problem whatsoever. However, when I built my house I equipped it with a security system that alerts me even if the sump pump overflows. Security is simply feeling secure.
Back in the 1960's when I was in college, I had my car broken into twice. Both times I was only away from it for a few minutes. The crooks work fast. Of course, insurance paid most of it.
In 1971 I got a carry permit and have been protecting myself ever since. No problems so far, but I am prepared. I don't do warning shots. I have factory ammo and I am trained. If I am ever accosted the perpetrator won't sue me. Maybe his heirs, but he won't be around, nor have a second chance to accost someone else.
