I very much understand what you're saying. I live in a trailer park and recently had our truck tire slashed and have had things stolen from our yard. I am 18 years old and I own a gun and my step dad is a cop. I can only open carry and if I'm going out to get the mail or go out to my truck for a second I'll put my gun on my hip mostly because I have to. I can't see my step dad showing off his gun and from my understand many people do know he's a cop (from what I heard from someone who went to my school when we first moved in). I do understand what you're saying but I'm not sure it will be a great deterrent. But you do have the legal right to do it.
