With youngins in the home, this is a real danger. During these years you almost have to establish a policy of shouting out and warning the target. It adds a level of danger, but I would sure hate to shoot my own kid or spouse.
They need to call ahead to get clearance to show up and be admitted....
Yup. Know your target. A rule not adhered to by a law enforcement officer. Just shoot at anything, dogs, strangers,… or your own kid.
When I worked offshore in the Gulf of Mexico sometimes I would get off the rig early. I would stop and call my wife before I opened the door of my apartment if it was at night. I did not want to get shot.
My brother once went to investigate a noise in the back part of his house. It was the wee hours of the night, and he went carrying a .30-30 Winchester. He met his youngest son in a hallway, trying to enter the house very quietly and get into bed without waking anyone up. By the accounts of both of them, this was a very narrowly averted catastrophe.
