Ah, but how do you plan to regulate it to keep guns out of the hands of "crazy rednecks" without breaking the 2nd amendment?
The same way I have advocated before, but in short: and appropriate licensing program that includes training and education, wait periods, background checks, interviews, and penalties for misconduct, probably at the federal level, or at least common enough across the states to make it consistent (similar to drivers licenses in spirit). I actually like the format of the MA licensing, the in practice bit could be greatly improved, but the intention appeals to my sense of right/wrong and fairness.
