From what I remember............the old people in the area were scared, because a few days before, there were some "hooded" kids going around trying to force peoples doors open, and if they couldn't get it, they tried the next house. Luckily they all had their doors locked and some weren't home.
So, it's natural to be scared when someone comes to your door, especially elderly people living alone.
And seeing this man had a solid wood front door, I doubt he thought about looking out his window first, seeing as there was a threat of breakins going around.
But then again, this is what the Pedocrats have worked so hard for........fear and suspicion between us all.
