Source: many years of carrying a weapon in a professional capacity.
I certainly don't expect I'll be able to address this from someone confidently bragging about years of "professional" experience carrying an unchambered weapon as the only right way to do it on the street, so hopefully you can find a class with someone with a background you respect so it will go through your brain.
Walking around on base for example isn’t even remotely close to one. This isn’t uniquely an American thing but it’s extremely common in the US in a way that absolutely isn’t in any kind of comparable country.
I don’t know what it is exactly, other than maybe the very weird and extremely pervasive “operator mentality” that seems to make everyone extremely horny for pretending situations are much more dangerous than they really are.
If you’re going to carry a weapon it’s really a very basic requirement that you can do some reasonable level of threat analysis and respond to the situation around you as it develops.
Again, I’m not saying those situations don’t exist where it makes sense but they are absolutely the exception and are a very weird thing to pretend are the default. I think it’s a culture problem and people are just scared.
On the flipside, when I got a flat on my bicycle in the city a guy walked up to me with a gun, pointed a gun at me to take my shit, and I would not have had time to rack a weapon (and god forbid it jammed). I knocked the guy's arm and punched the guy which stunned him enough that I was able to run off without him getting a good shot off; I would have had enough time to get off a shot with a chambered weapon (didn't carry at the time) but I never would have stood a chance if I pulled out an unchambered gun.
The only scenario where things start to get ACTUALLY dangerous is you pulling out a weapon and suddenly you’ve gone from a 5/10 situation to a 10/10 situation where everyone is liable to panic and do something stupid. You’re about to go from a bad day to maybe your last day here and for what? There is just no point in that story where adding another weapon to the picture improved things at all.
On a side note, I think there is a LOT to be said for having a strong sense of situation awareness and how to do risk management on the street. I spent a good amount of time years ago living in Nairobi and I was one of the few people in my circle of friends who didn’t have a gun in their face at any point. I’m not trying to say I’m somehow special, I think that can happen to anyone but I wish people didn’t have their entire personal security model centered around having a weapon because it’s actually a really shit plan in real life.
Edit: I don’t know if you’re familiar with Robert Young Pelton but he is a war correspondent wrote a book called the worlds most dangerous places which is part adventure travel guide and part how to stay safe in actually honest to god dangerous places and situations. He just started a podcast based on that book and I think you might get something out of this: https://youtu.be/3dhh5_oJsqQ?feature=shared
And yeah I've been in the third world, including Syria. I think the penalty for me having one in Syria was probably the death penalty (LOL!), I didn't give a shit. Some people did shoot at me, I survived.
But that is just being scared and has nothing to do with actually assessing and managing risk.
I understand that’s become a very normalised thing to do there but is something that would get you laughed out of the bar in pretty much the rest of the English speaking world.
Again, I don’t know what to tell you other than I think there is a paranoid culture problem here where everyone is just terrified of everything all the time and nobody seems to know how to step back from the edge and deescalate or again like I keep saying learning how to ACTUALLY judge and manage risk. It’s an actual skillset that will serve you much much better than a weapon ever will.
The same thing goes for just learning how to not panic if you find yourself in a sketchy situation. The ability to remain calm is hands down the most impressive and helpful thing I’ve ever seen from the actually dangerous people I know and have spent time with in some capacity or another.
I had to take one to get my Texas License To Carry (at the time a concealed carry license). I don't know what they teach in other states, but Texas has strict regulations on when and how to use deadly force. Including when to point a gun at someone.
Basically, not having a round chambered means you're too late to do anything with that gun other than use it an expensive blunt instrument -- or -- be possibly charged for brandishing/intimidation. Either you are being approached/charged at and are in immediate danger of bodily harm or you are not. If you are, you better have a loaded round ready to discharge.
Ofc, there is also the use of deadly force to protect the immediate and active threat to personal property. No real immediate need to have one loaded here. However, I don't think people carry because they are waiting to shoot someone trying to steal their car or other property under the Castle Doctrine. Which if someone is willing to kill another who is stealing their parked empty car, there are bigger talks to have other than if they are carrying with a load round or not. I don't usually keep a round chambered at home, my siblings have offspring that come around and even though it's a bit of a family tradition to learn to learn gun safety and shooting before age 10 -- I still don't care for the thought of a fully loaded gun not in my immediate possession.
