I can understand now why you believe as you do. However, you cannot expect everyone to share that point of view. Many folks have never even touched any kind of gun, much less used one aside from tin can target practice. The thought of carrying one around with intent to kill can be unnerving to those who don't live like that.
Fair enough . Not much crime being committed in my neighborhood either probably for this very reason.
Matter of fact I can leave my keys in my truck all night walk outside in the morning and its still there. And most of the time I don't even lock my front door unless I'm gonna be gone all day.( my neighbors have fire arms also and we watch each others houses) this is our neighborhood watch ! And it works very well !!
