That’s the only concern I have with permitless carry.
As a former instructor I used to see a lot of dumb shit in our entry level/CWL classes. Not everyone should carry a gun. Personal responsibility is the foundation of many of our laws and the number/percentage of the population who value and understand that concept has dropped to dangerous levels.
That said, I get the whole Constitutional carry thing, but frankly our society has sunk so low that I still think some formal training (not just range time but legal/ethics classroom education) should be a requirement. Just like a drivers license.
Unlike the 2 hour certificate mills, our entry CWL course was 4 hours classroom and 4 hours range time with a qual. We charged $150 while the certificate mills charged $40 and basically walked you through how to fill out and submit the application
