The "automobiles kill people" argument is actually a good tip.

1. Mandatory minimum age to operate on public roads.

2. Extensive theory knowledge required before a practical test is allowed.

3. Very critical road-test required before a provisional license (some States).

4. Violation of provisional standing suspends license and may cause impoundment of vehicle.

5. Rapid harsh consequences for operating under influence, including possible jail time.

6. Under some circumstances may be charged with vehicular homicide.

Given that firearms are more lethal than automobiles, and are intentionally designed for harm, unlike automobiles, why should these parameters not constitute the MINIMUM prerequisite to gun ownership?
