I disagree. There have been many instances where a burglar was surprised by a resident they didn't know was present when they broke in.
We had a case like that near my house. High school kid, age 15, was home sick from school. He was mostly sleeping. He woke up and heard someone in the house, thought it might be a parent. Came out, surprised a burglar who shot and killed him. Devastating.
Guy was caught pretty quickly, says he was startled, that he had his gun in his pocket and it "just happened." Convicted of second degree murder (he pleaded out) and is doing 15 years to life with enhancements.
There are several other cases of this type. An armed, young burglar is liable to "make mistakes" that he didn't intend when he broke in.
There are other cases in apartment buildings. There was a spate of burglaries in a huge apartment complex we used to live in, leading most people to consider buying guns themselves (we didn't, we were moving out soon, but it was very scary). Every time anyone came home, they were worried, especially if on the higher floors, because a burglar's exit could be blocked and result in violence. It was happening all up and down a long street of apartments.
I actually had a hot prowl in a condo we had rented - I thought my then-husband had forgotten something, as I heard the downstairs door open and could hear sounds as if someone were opening and closing the drawers of the desk we had near the door. So I went to the top of the stairs and started down, saying, "Did you forget something?" (We kept cash in a different place - I was thinking maybe he was looking for it). I heard running feet and the door was wide open when I went downstairs. Very scary. Sleeping 2 year old upstairs.
We will eventually get more details at this case, at the arraignment. Where I live, hot prowling leading to assault is a nearly weekly occurrence (sexual and otherwise). Not right in my neighborhood, thankfully, but not too far away. I know a woman whose house was entered almost daily by the same man (who was using her shower, sleeping in her bed and eating her food - she got cameras, but he then started turning off the electricity as he entered; she had to get trail cam type cams - needless to say, LE did nothing with the pictures, which were hardly identifying - she simply gave notice and moved; single mom).
So yeah, "burglary" spans a wide number of behaviors here in the urban wilderness of SoCal. It's just more shocking when it happens in a small town.
