The usual suspects are coming up with the same tired old ideas to implement gun control, usually incrementally, so we don't see confiscation creeping up on us. It's a game as old as the hills, and it'll go on as long as the hills are there.
One idea being advanced (again) as part of a "Green New Deal for Guns" is a gun buyback program, this time mandatory rather than voluntary. Of course, it's logically nonsensical; how can the government (or anyone else) buy back a gun that was never theirs in the first place? However, logic has never stopped a gun-grabber. I think Clint Eastwood put this idea firmly in its place some time ago.
“Participating in a gun buyback program because you think that criminals have too many guns is like having yourself castrated because you think your neighbors have too many kids.”
I also like another of his quotes on the subject:
"I have a very strict gun control policy: if there's a gun around, I want to be in control of it."
