"Profiled"? Well, of course. As a white, middle-aged, heterosexual Christian male, I'm profiled many times over. The larger worry is being "on the list" - which I most assuredly am. Back before the anti-gun crowd caught my attention and made me re-evaluate certain practices of mine, I bought several firearms over the counter from a local dealer. Years later, that dealer was investigated and eventually the FFL holder was convicted of selling guns to felons. All the transactions were legit, as I understand the regs governing FFL holders; it was an ATF fishing expedition. But I digress.
Bottom line - ALL of the dealer's 4473s were seized. So, the feds know what I bought there - as well as the purchases by many others, including my dad, cousins, friends, etc. We're all in the database. So now, I consider all of the stuff bought on a 4473 to be "sacrificial". It's not the entirety of my collection, though... and it's certainly not all in one place.
Here's another thought: Do y'all remember the Smith & Wesson "agreement"? Well, it's not dead. In fact, I think I just saw it twitch.
Yeah, I can see where an activist Federal Judge could link a search warrant to every one. Agents could go online for a particular 4473 and the server could come up with all kinds of information plus a ready made search warrant. Is this a wonderful country, or what?
