Honestly Delphi, this looks remarkably like the Canadian laws.. it's not working so well up there. I had the chance to talk with a Canadian shotgun collector; for instance he can't even display his replicas because of their weapon security laws.
Manditory training, even if it's the intro to firearms course that the NRA offers or the likes is a good idea for certain. I don't disagree with some of what you say, but the good ol' second ammendment doesn't require safes or training and I'm going to side with the founding fathers on that one.
