I have been told that having NRA stickers or other gun warnings (like “Security by Smith & Wesson”) is pretty much announcing there are guns to steal inside. Sort of like putting up a sign that says “Gold and jewel collector lives here”.
Also warns that bad guys need to be armed and ready.
Sort of like how Video Surveillance signs remind them to put their masks on. Lol
I live in a bad neighborhood & my neighbors on both side of me have been broken into, but not my house. I think that the sticker on the door has a lot top do with it.
