From The Truth About Guns:

The biggest reason we don’t have an astronomical rate of gun deaths is simple: people generally choose the best option for their own circumstances without orders from the nanny state. This “self-selection” contradicts the idea that we need to be micro-managed for our own safety.
As a result of self-selection, much of what the anti-gun lobby claims they want to accomplish has already been done individually by the people themselves at zero cost. No tax money expended, no freedoms restricted, no need for state-mandated mental health exams.years.
