“Accidental gun deaths are fully avoidable by proper education, storage and usage.
We don’t ban cars because they kill more lives than they save.”
Require certification of proper gun education and storage facilities prior to permitting gun ownership and/or usage.
A driver’s license requires a driving test be passed. A firearms license (surely) should be required with the aforementioned prerequisites, as well.
As an aside, a separate point I would like to make is that hunting for fun (not food) should be outlawed.
