I am always amazed to see how many people think guns are registered "to them".
Had a conversation with a coworker not too long ago who thought things were like TV...a gun shows up at a crime scene, and like Perrry Mason, the cops know exactly who bought the gun, when, and if it was ever sold to anyone. He was slack-jawed to learn the AFT didn't have a central computerized registry of every gun ever sold in the US. I had to explain the actual process of "gun tracing" and how is is far from accurate. That only a handful of deep blue states had anything that resembled a registry. I gave him the hypothetical that as a non resident I could move to MA and own 100 guns and no one need know. There is nothing on an LTC/FID that ties me to a specific firearm. Then I had to explain to this disenchanted coworker that ballistics is not like TV either....and that it rarely possible to declare a bullet came from a specific firearm unless several conditions are met.
Another friend of mine (RI resident) was given a gun (sweet S&W 357 mag revolver) by his (now late) mother. It belonged to his deceased father. He said he wanted to come to the range with me and shoot some time, but first he had to get his license and he couldn't leave the house with it because it was not "register to" him. He got this vital information from his coworker....so I said in my best family guy voice "You know, not for nuthin' but you coworker doens't know crap about guns....I'll be be Saturday and we're going to the range"
