Agreed. It's the worst kind of non-random there is, choosing victims who are perceived as not being able to fight back and killing them because it's easy.
Anyone living alone should have a dog, and not one that they can carry around in a pocketbook.
Unfortunately old people sometimes get a bit squirrely. My mom was the victim of an aborted home invasion some years ago. She was in the kitchen chatting with a neighbor when one of our junior citizens tried to kick in the porch door. He managed to virtually destroy the door but did not gain entry all the while my mom was present a few feet away telling him to go away. I asked her why she did not just use the gun my dad left and just blast through the door. She said “I thought he may have been lost or had the wrong house”. I said mom you were lucky to be alive because any lowlife who would try to break in knowing someone was present was intent on serious crime. I moved her out of her life long home shortly after that.
