Even civilian concealed carry training has some hands-on courses to teach why it is trained this way. You’re also taught, “only draw your weapon if you have intent to kill,” which is sobering in and of itself.
This leads to the bigger question: why does US cop training paint every scenario as “time to pull out the hammer, I see a nail!”? That’s fundamentally wrong at its very core. “Oh, shit, an acorn! blam! blam! blam!”
It seems the very antithesis of the US legal tenet “innocent until proven guilty” as one can’t be innocent nor proven guilty if they’re already dead.
