Earlier quoted context omitted.
It's a reasonable guess, but 8:30p seems like a dumb time for a home robbery. Usually they're committed during the day when people are at work, and if not that then deep in the night for maximum cover. 8:30 is almost like the ideal time if you actually want someone to be there and answer the door at an hour where it wouldn't cause enough alarm for them to answer the door with a weapon.
When it comes to small-scale crime like this, the smartest thing is typically not to do it at all. So the people who do it will generally not be very smart.
You mean murder?
