Well, there is no such thing. This is my proposal. One side of the political divide is characterized by those who feel that that 47% of us are "takers" . Many advocate that we all carry a gun as responsible citizens, as it is the ONLY way to protect ourselves and others. Those of us who are not armed in this world are seen as irresponsible. I just wish to carry this to its logical extreme by proposing a Gun responsibility act.
IN this gun responsibility act, the gun owner--now this will come as a shock--will be responsible for his or her weapon at all times. Translation, if you leave your weapon in a desk drawer and someone breaks in and steals it, you were not carrying out your duty to keep criminals from being armed. If your six year old granddaughter finds your pink pistol in a drawer and shoots her three year old brother, obviously you did not fulfill your legal duty to be responsible. You can still own the weapon, but you have to be responsible. If you try to get your keys out of your pocket and your concealed-carry pistol shoots your balls off, or shoots your wife in the leg, you were not responsible. If your kid shows up at school with your weapon in his backpack--Maybe you were responsible. If a burglar uses a cutting torch to remove your guns from your gun safe you probably did carry out due diligence--unless everyone knew there were a lot of unattended guns there. You likely were irresponsible if the gun was kept in the heirloom antique glass case or on pegs over your door. Shoot yourself while cleaning a gun--irresponsible. Not able to show that you are adequately trained in gun safety--also irresponsible. You don't have the mental control to keep from shooting people--irresponsible. You lend your weapon to your brother, and he proves to be irresponsible, then you did not vet him correctly and have a responsibility; if he does something criminal with it it is that much worse for you. You sell your gun to someone irresponsible (or you don't know if they are responsible)...you know the drill.
Irresponsible gun ownership should carry stiff penalties and and allow for deep liabilities. Oh yes, and you should have liability insurance. And liability insurance may be taxable.
My gunsmith friend suggests that a responsible gun owner needs to demonstrate that she is responsible by demonstrating that she does not have the intention of going out and committing a crime and the ability to not act impulsively. This might require that they subject themselves to some sort of mental health exam, or have their psychiatrist write a letter. I'm sure that a lot of the people waiting for the apocalypse would be happy to comply.
I imagine this community can improve on this idea. I don't know what to do about gun resgistration, but it kind of has to happen at some level for this to work. It might be kind of nice also if all gun barrels sold had a ballistics specimen on file. I don't know if technically that could work, but someone out there does.
