In 1980 my brother shot one of his neighbors through the window while the man was watching Billy Graham. The door was locked. He shot the knob. That didn't work. So he knocked in the front window with the butt of his gun, went inside and shot two adult. They died, as did two more neighbors down the road. He shot them through the window also. Thus began the most horrid nightmare. It nearly destroyed my loving parents, and I had to help them cope. They were at his house at the time he sneaked out his gun. I mentioned this on this site years ago. It not only destroyed the lives of his victims and their families, some of whom we knew, but also destroyed my marriage - my husband was ashamed of me because of my brother's actions. It destroyed everything I believed in. Except for my sister none of my family was there for me, and I was the one who took care of the legal stuff, etc. I'm bringing this up now because I want to dispel any illusion that there is safety. One can take precautions, but when someone is determined and mentally unbalanced because of prescriptions drugs they can do anything. My brother is a case in point. He finally died in prison in 2016, and I no longer had to fear him having me killed.
