At the risk of sounding paranoid I've got a few questions.Doorbell rings while I'm handloading ammo. Wife and daughter are watching a movie in living room. I answer door (without ccw) and step outside to talk to a man and woman that say they work for kirby and want to give my house a free cleaning. While I'm in the process of sending them on their way my wife calls me back in the house to let me know that according to facebook people are scoping out houses in my neighborhood. So I grab my ccw and go back out and tell them NOT INTERESTED. This most likely is just a false alarm not worthy of calling police IMO, but I did go back out and watch them walk door to door down the street.So basically all I did was get their license number from their truck.Questions that I have is how are you supposed to handle door to door salesmen?
