And let's think of it this way - the specific reason people have the "right" to bear arms is so that they can fend off an incipient tyranny, which the anti-Federalists were deeply suspicious of - in that case the traceability of bullets is of no interest.Worse than it being "of no interest" -- let's just say that Civil War 2 breaks out. This time, the side that I'm on (whichever side that is) loses, but I survive. The other side takes some slugs from their dead soldiers who I shot while they were coming down my street. They remove the slugs, and do your AmmoTracing thing, and they trace 'em back to me (forget, for the moment, that I wouldn't be dumb enough to use trackable ammo in this instance.) I get a couple of knocks on my door in the middle of the night, and it's The Other Side, with a house call from Sir Reaper.
Because one would assume that local people would want to use local bullets...Who is "one"?
I think that this whole discussion we've been having shows that *you* are the lone person subscribing to the "one" here, Ross. The rest of us are rather adamantly saying no.
