Fr. Z's Situation Awareness FAIL!
I don’t know about you, but over the last year or so I have become increasingly disciplined regarding my situation awareness. When I get out of my car, I look around to see where everyone is. When I walk out the door, I look around to see where everyone is. When I walk into a place, I look around. I know where the doors and exits are. I see where everyone is, who comes in after me. If I see someone that looks or behaves oddly, I keep an eye on them.Source
