The author might be taken more seriously if it weren’t for the lessons of Prohibition.
Back in the 1910s do-gooders made a strong case for the prohibition of alcohol. Alcohol caused such misery! There was much truth in that statement. So alcohol was prohibited.
What was the result? Law-abiding citizens had no alcohol. But anyone who was willing to skirt the rules could have all the alcohol they wanted, and more.
Substitute “firearms” for “alcohol” in the above, and you will get the exact same story. The 2A aside, banning or surrendering firearms just won’t work in practice.
The law-abiding citizens will have no guns. The thugs and the hoodlums will have all the guns they need.
