Federal and state agents went house to house asking if people owned guns, specifically .223 weapons. (BTW, how do you think they know who to ask?)
Righto. I have another account via third person, an FFL, who conducted business with a LEO. The LEO had relocated to a different department and was asked to list all of his guns to his employer, which was not a federal agency. He omitted one gun, a ruger 10/22 IIRC, and the chief pulled him aside and stated they knew about one more gun that he had but did not list.
This may have been a state issue, but there is a database somewhere or this and my quoted portion simply could not happen. But they do. In this regard, I don't trust my government. Federal laws or not, it doesn't mean they're not collecting the data and filing it somewhere. As stated, how did they know who to ask? If there was no database, then this task should be impossilbe shouldn't it?
Besides all that, buy all the guns you want and enjoy them. As stated in previous posts, people are irresponsible, criminal and reckless, not guns. If you do your part, it'll never be a problem. As much as Illinois would have you feel like one, a gun does not make you a criminal.
I recall going to a party back in my college days and someone brought out an AK47. I obeyed the four rules and proceeded to pose with it for pictures. I never got to see the picture but bumped into an old friend a while back and he stated how good the pic of me with the gun turned out. I always worried that it might have somehow been a issue should it surface at some wrong time in my life. Not sure why, just did. Now, 20 some years later, I really wish I had that picture.
