Again, not sure if serious. No actual experience with the available classes or with carrying a firearm but you want everyone else to carry "your way"?
A cop (or anyone else for that matter) who has to deal with people in a potentially adversarial interaction would be foolish to assume that the other person is NOT armed. Best practices aside, some states require a "duty to inform" police that you're carrying and some don't. Carry permit or not, legal or not, Constitutional Carry laws or not, bad guys probably aren't going to admit they have guns. Constitutional carry doesn't magically put guns into the hands of bad guys, doesn't make it legal for felons to own or carry firearms, and in the grand scheme of things doesn't really change anything other than not forcing people to sit through a useless class and pay the state for permission to exercise their rights. I can just about guarantee that almost everyone would probably be better served using a full day's worth of hours and couple hundred extra bucks for ammo and range time or a real training course instead of the paperwork fee and state-mandated "training" classes.
