Sorry to hear that someone tried to break in. I would advise against posting signs that your house is protected by firearms. I think that's an advertisement to criminals that there's guns in the house. Same goes for vehicles. As much as I really would like NRA and other gun stickers on my car, I don't do it because it's advertising that I have guns and don't want someone following me home to see where I live and break in when I'm not home. Just my 2 cents.
