If you were right, then most militaries and police organizations in the world would be wrong. That seems implausible.
……
You might think that without first hand knowledge.
Let’s start with police officers first. While sure you have your Tackleberry’s, most cops are not gun people.
Can’t tell you how many cops go to annual quals and fail only to have to go to the remedial firearms course just to squeak by on their re-qualification. And I do not mean once in a while, I’m talking every single annual quals, year after year.
Officer had x2 ND’s still made Detective.
Suppose to carry REM 870 in “Patrol Carry" or "Patrol Ready" (different names same thing) in patrol cars (Safety off, trigger pressed and then load tube so if you need it you just rack the pump and good to go. Simplest way to deploy for idiots) and still managed to put a round through the roof of their patrol vehicle grabbing it from the rack.
I could keep writing for days about stupid

cops do because they do not take the 4 rules seriously enough. Add stress and bad things like NDs happen. That is just one department.
Now militaries, can’t tell you how many times supposedly well trained NATO forces fired on us by “Mistake” because they didn’t know where the F’ they were and just shoot.
Then, training, and/or training alongside them is even more completely F’d. Remember one time, a Middle Eastern Ally army was using blanks for training with out the muzzle device blank adapter. Basically made their M16’s a bolt action operated because not enough gas return to cycle bolt. Well they thought it was funny to put barrels next to people’s head and pull the trigger, or body contact shots, etc. Yes, that can end badly for someone.
So you see, the 4 Safety rules and actually training is way more important than a dumbass mag disconnect.
Also, as long as cops remedial train and qual, they can keep working year after year without ever getting better or safer. Surprise you? Sure surprised the heck out of me too. But as long as they eventually get the “Pass” they are right back in a patrol car. Cheaper to keep them than replace them. Also, as long as the do eventually pass, legally they are good to go and the department is off the hook because they passed quals.
Because honestly, most will never fire their issued sidearm on-duty. But you might say, but they point their guns at people all the time and bad things can happen. Well, instead of more training, this department made it a “Use of Force” to point your weapon at somebody requiring paper. And we all know how cops love writing reports. So that cut that down a lot without costing money or more time training.
Just saying
