Their is always a man with a gun on my porch and it is this man. I don't open the door if I am not expecting anyone and even then the screen doors stay lock. I will go out another door and lock it behind me and walk around to see who it is if I did not have prior notice. Even the mail lady and police honk when they come down the road around here because people have dogs, donkeys and all kind of protections for themselves and their livestock where I live. Keep fighting the good fight.
