Under current conditions, increasing guns will increase deaths - by whatever degree.
In order to preserve existing individual liberties, we must institution protective principles in-measure to the laws, regulations, or other systems we instrument.
In other words, we must change current conditions to maintain the individual liberties we have today. Changed conditions can allow the same, or increased, gun ownership without more deaths — or even less deaths.
This "protective principle" I have written about here, and call a "Commutative Principle". I propose this principle as a fair way to regulate rights / liberties, as a guarantor that means are contemplated for the safe absence of regulation.
