I’m curious how the current “system” works. Follow this scenario. John buys a gun at a local firearms store. He keeps it for a few years and then trades it in at a different gun store. This gun store keeps it on the shelf for a few months and then sells it to Doug and files an additional form 4473 for the transfer. Doug keeps it for a while, he doesn’t like it and sells it on ODT. The gun goes through a few private transactions and ends up being used in a crime and the police locate the gun. Questions : 1) Is there a computer tracking system that will show every time that serial number is placed on a form 4473? 2) Will a police search show both transactions at each store? Will they contact both John and a Doug trying to locate the criminal? 3) Obviously private transactions do not need a bill of sale and law enforcement would have to contact each owner along the way to find the end user criminal. Right? The gun law debate can get stuck on the private sale of firearms and the wrongfully described “ gun show “ loophole. And I am concerned that sites like ODT will be the target of further legislation. I like to be an informed and not an ignorant gun law debater, and I really don’t know how things currently work.
