You sicked the IRS on them, the end game will either be prison time or property loss. Seems like unintended consequences would punish a victimless crime, we do way too much of that already.
I hate hand guns so I'm not defending my own rights. Just understanding the 2nd and it's purpose I would never think to limit this. In fact, I'd be cool with my neighbor owning tanks and scud missiles. I'd make friends with him if I could, move if I couldn't.
