I'm not advocating registration. But I find it odd that the paper records that out of business shops send to the ATF is REGISTRATION if they are digitized. I never said that ALL 4473's be sent to ATF. Just the digitization of the records they are already being sent. It's irrationalIt's not anyone's business if I own firearms. It's as simple as that. It's not fear. It's a matter of "your business/not your business". You don't need it just so it's more convenient for you to investigate.
I'm very comfortable using the "need" argument when it's authority vs personal liberty of citizens. What do you do when the gun has changed private hands umpteen times? Do all those sales need to be recorded too?
