It’s pretty clear in these uncertain times that there’s a New Normal out there. There will always be the possibility of a terror event or shooting whenever crowds of people gather. Almost daily, a terrorist or madman causes death and destruction somewhere. If you learn to be situationally aware, you won’t be a soft target for these savages.
The basics of situational awareness are described in what is called the OODA Loop. It was first devised by Air Force fighter pilot Colonel John Boyd. Originally meant to help in an aerial dogfight, it’s useful in all sorts of settings. The four steps of the OODA Loop are: Observe, Orient, Decide, and Act. It’s a loop because you go back to the observe step after you act, to determine if the situation has resolved or if further action is needed.
