I think (as someone else noted before me), that a lot of the opinions here about something being unusual are coming from people without experience committing violent crimes or being victims of violent crimes.
For example, someone commented that it was unusual the guy wasn’t running away from the crime scene. But what is the only reason to run from something? If someone is trying to catch you. We know someone was at the door. Whether that was a victim or an accomplice (likely victim), that means he knew the cops hadn’t been called (being escorted to the door may have been the condition on which he agreed to leave, perhaps when he found the house unexpectedly occupied by a lone young girl). He also knew the occupant was trying to get rid of him, not catch him. And sprinting from a residence could attract unwanted attention from neighbors.
After I was robbed of my purse on the street in LA, I didn’t run away from the robbers, I instead calmly turned my back to them and walked away. My reasoning:
1) I didn’t want them to think that my running was an indication I had more on me that I didn’t want them to get (like jewelry or whatever). They could have pulled out a gun and shot me if they thought it would be worth their while. Wouldn’t have been the first time in the area I was in.
2) Didn’t want to trigger any sort of irrational chase instinct they may have had.
3) Would have been futile. We had the same starting point. They were two men and I am a woman with exercise-induced asthma. Running was not going to be my winning strategy.
I describe how the whole thing went down as “peaceful, as far as violent crimes go.”
