I hope that we never have national gun registration in the US. Just recently, California passed a law allowing the police to confiscate your firearms on the sole basis of a family member's or ex's claim that you're a danger to yourself or someone else. For 21 days, you don't even get a chance to defend yourself. The confiscation and ban of gun ownership can then be extended for one year, without a conviction for a single crime.
You also have politicians all over the country who openly admit that they would ban and confiscate all guns if they could. You have half of the Supreme Court willfully misreading the Second Amendment as giving no rights to people, only to states.
It's easy to see where this is going. Everyone who values their right to keep and bear arms will fight tooth and nail against any national registration proposal.
