The narrator definitely has some confirmation bias believe me. That said it was more his central point that I agree with. If you are going to carry a weapon don't assume that the weapon alone is a "magic wand."
I probably agree. While it's not a good luck charm or talisman that repels evil, it sure looks like just showing one makes the bad guy go away at least 2/3 of the time. While not a magic wand, it sure seems as close as I'm likely to see.
As for people having their guns taken from them, while there is no statistic for officers who are "simply" disarmed, a number of studies have been performed that show of Officers who died from gunshot wounds, ~10% were shot with their own gun.
Sure. No argument there. My only caveat is that the vast majority of people who carry for self defense aren't LEO. Two very very different goals. On the one hand, self defense minded non-LEO civilians have basically one goal: to make the bad guy stop doing whatever it is he was doing that made you need to deploy the gun. That's it. LEO, on the other hand, have a much more comprehensive, and demanding, requirement. Capture, restrain, and arrest puts LEO in a very different position, both "tactically" and philosophically, from someone carrying for self defense. Cops have a much greater need to be able to "fight" at that (or any) range than someone carrying for self defense.
The two groups have different goals and so it follows that what is effective for each will be somewhat different. To be honest, I have a bit of a problem with CCW people taking classes intended for LEO, or worse, military application, and believing that the material is 100% applicable to their needs.
CCW holders aren't cops, shouldn't try to be, and should be reminded of such.
Peace favor your sword,
