In my case, I would say nothing at all and consult an attorney.
You will have no idea just what trouble you might get into by even admitting to having ever owned the weapon in question. You have little to lose and potentially much to gain by refusing to be the source of any evidence whatever.
Have you watched the videos on Youtube explaining why you should NEVER talk to the police?
To summarize the most important point I got from the videos: "Even if you tell the absolute truth, you may come under suspicion if your otherwise irrelevant but truthful statement is mistakenly contradicted by some other trustworthy person whom the police choose to believe ."
If you make no statement at all, there will be no contradiction.
Excellent point. You’re innocent & confident that the truth will out. The police are there to count coup & hang the coonskin on the wall.
In grade school we were introduced to Officers Mike & Steve who said, “If you have a problem, come see us. We’re your friends.”
How times have changed.
