As the year comes to its end, I've been reminded of several instances of real life threats, incidents, attacks, i.e. personal safety threats caught on video and circulated on the internet. In most cases the attacks were successful primarily due to the element of surprise, as they came unexpectedly and caught the victim(s) totally unprepared. It completely skewed their OODA look (do some research if you don't know what it is) and tipped the situation in attacker's favor. The victims' thought process was typically paralyzed (more about the wrong questioning in the next post), thus further impairing their ability to react.
So, succinctly put, the main problem was the lack of situational awareness by the victims. In the personal protection circles it is one of the pillars of effective (re)action and often mentioned, albeit not always explained in detail. I won't go into it deeply either, but let's see what are its main components.
We see that the first phase of developing good awareness is to track what is going on in our surroundings. It effectively means not going around in the "autopilot mode", and instead be present in the given moment. That does not mean paranoid, but actually involved in perceiving what is going on in the overall sense. Essentially, it is like driving during rush hour - yous can't allow yourself to doze off, but no need for super focused, nerve taxing attention either. After all it is (still) not a NASCAR of F1 race.
The next component is comprised of comparing the info received against the background of habitual baseline that we have for a given time and place, in order to establish whether the situation is somehow deviating. If not - just carry on; if yes - how is it deviating and does it require more concern.
Finally, in the case of relevant concerns, we ought to make general predictions of how the situation may unfold and decide on appropriate action, should our predictions show to be true. Namely, this accelerates the action, if the push comes to shove, as they say.
By the way, this is also the summary of the above mentioned OODA (observe, orient, decide, act) loop.
OK, now you have the basic idea. However, as it is always the case, in order to ingrain this knowledge into a useful habit, some practice is needed. This is, of course, a subject that can be treated in depth, but let us get at least a basic start.

The main thing is to break out of the bad habits and harmful state of mind, such as being lost in phone conversations, email correspondence or mindless scrolling when on the go. To get the ball rolling, give yourself an assignment next ime you are in public transport or walking the streets, especially the routs you know well, as those are typically where our autopilot takes over. For example, make sure to note all the people who wear a hat, or a scarf, or a piece of clothing of a predetermined color. Next, strive to pick up certain actions, e.g. moving with hands in pockets or unusually quickly, against the crowd, too slowly, looking lost etc. Don't neglect your hearing either - try to identify some type of sound! Can you differentiate between the sound of a passing bus, truck, motorcycle, car? Sounds coming from a construction site or a school yard?
The point is not to try and do it all at once, especially if "waking up" after a long "sleep". Take one step at the time, spend a couple of days at each assignment and things will gain momentum soon enough.
Now, this reminds me of a comment I read from Terry Trahan (founder of WeaselCraft, check him out): in order to develop good situational awareness, you need to have some environmental awareness first! It means going back to that baseline we mentioned before, i.e. knowing what kind of general social behavior is normal for a given place or space. What might be normal or acceptable in a park or on he playground may sound your alarm in a workplace. As a matter of fact, the normal overall atmosphere could differ radically between two establishments of the same purpose, but in different places, e.g. a bar in the blue-collar part of town during the home game of the local sports club on weekends, and the fancy restaurant in the business area during lunch time mid-week. You get the idea...
Being aware of those factors and attuned to your environment, with appropriate state of mind (do a quick search for Cooper's color code of awareness) should ideally prevent the situation from turning really bad in the first place, or at the very least prevent you from finding yourself freeze as the proverbial deer in the headlights.
Take the step in the right direction and help the new year be good to you!
