How can we regulate guns ... ?

Registration wouldn't really help with kids being killed accidentally by guns. We generally know where those guns came from and who the gun owners are.

I guess I missed the word 'invaders' in the Second Amendment.

The Founding Fathers, and their 'intent' is completely irrelevant.

As I already pointed out to RAZD, cartoons aren't an argument.

The discussion on the Founding Fathers is side-tracking the issue.
Policies have been proposed.

I am a gun owner and have been quite immersed in the gun culture for many years. Talking with family and friends I can say that my general impressions are that this is sorta kinda where people I know are falling out on the issue.There is a desire for more gun control among gun owners I know. There are also the dead enders like that asshole from Kentucky. Guys like that are helping drive this nation toward substantive gun control.

The point was not that 3D printers prevent you from passing laws, but that they could make control impossible.

Please realize that the gun owners I associate with now are not the own a gun for guns sake and to prove my manhood type of gun owners. For the most part. I do know a couple end of worlders that feel any regulation is bad, but they are a small minority. These are guys that are hoping for a zombie apocalypse cuz they think it would be cool.

This is consistent with my idea of putting the NRA in charge of guaranteeing Gun Show accountability by requiring all buyers to swipe their NRA membership card and enter their PIN number (humorously termed the "Firing PIN") for each purchase around the nation. The NRA would be responsible for keeping the database of background checks for all the memberships. They would be liable for guns getting into the wrong hands or members spoiling their backgrounds to the point of revoking their membership cards. The US government would not have access to this database, so all the nutjobs could NOT whine about Nazi-Communist Islamo-terrorism taking over our government.Perhaps this could be extended all weapon purchases anywhere the NRA has jurisdiction someday.But this will not address inner city criminal usage.

In my opinion, enforcement would be utterly infeasible to accomplish. We can catch people purveying kiddie porn because 1) perverts have an insatiable desire to catch more of it and 2) it's illegal everywhere. But think of outlawing gun CAD files as something like outlawing DRM circumvention information for DVDs? That's stuff was impossible to stamp eliminate once it got on the internet. For decades that stuff was only illegal inside the US.

The States need to be protected from the Federal government just as the people who had come from England and other countries needed to be protected from the oppressive actions against the colonies in America.

If the States became a part of the union by ratyfing the constitution they can by the same vote withdraw from any State or Federal government that ceases to obey the Constitution (contract) they agreed too.

But that job has already been assigned by the ATF to licensed dealers.

But how serious of a problem is this? What percentage of guns used in crimes are actually obtained at gun shows?And what percentage of criminals who obtained their guns at a gun show had a background that would have disqualified them?

Why? What would this accomplish?

I would only note that in the areas of high gun death it's no wonder the people living there want to stop it. If it doesn't happen in your backyard, well, that's how life goes. Out of sight, out of mind, so to speak.This picture is rather damning for the knee-jerk liberals
