You will not find me in such a place at such a time.
I am very cautious about where I find myself in fact. I mostly limit my activities to familiar areas and frequent those areas only during the light of the day because I have also noticed that predators tend to come out at night. I am specifically looking to avoid trouble. I do, however, occasionally, find myself having to cross a dark parking lot after leaving a movie theater or restaurant on "date night".
That being said, it is difficult for an individual to enter by "tueller zone" without me being acutely aware of the approaching intrusion. I am looking for it and it happens. It's usually the drug addicted pan handler coming up to me to tell me his BS hardluck story. When I see them coming, I typically tell them "I don't have anything for you. Don't come any closer to me" while I'm moving my jacket out of the way.
I have definitely observed that these drug addicted panhandler types get more aggressive in their pan handling as it gets darker. I ordered one of them away and he called me a "dick" (yelled it in fact)and then went right up to someone else who was getting out of their car and got right in their face and they gave him money. Were it a little bit darker, and were that parking lot just a little bit emptier, and had that junky started to go through withdrawal, the panhandling would have been outright robbery. I get a 911 alert on my phone for every 911 call within a mile of my location. Robbery alerts are not uncommon in that particular area.
So, my point is, situational awareness should be a key component for any concealed handgun training program IMO. Battles are won or lost before they're fought. As a law abiding citizen with a CCW permit, you really shouldn't ever need to execute a combat roll but, if something has gone horribly wrong in your life, and you have found yourself in the wrong place at the wrong time, it seems like a great technique to have down. I especially liked the falling backward technique although, once your down, your ability maneuver is pretty limited.
Wow. You are quite the writer of the experience. Please, tell us more......
