Actually, I *don't* agree. Personally, I don't care if every violent felon in
America owns a dozen guns. What I care about is if they *use* them to commit
crimes. I don't care if they use them for target shooting. I don't care if
they use them for hunting. I don't care if they just collect them to look at.
If they aren't using them to commit crimes, they aren't doing you, or me, or
anyone else, any harm.

I think we need only one firearm law, really -- use a gun in the commission of
any crime, you get a mandatory ten years in a Federal penitentiary, over and
above the sentence for the underlying crime. No parole, no early release, no
time off for good behavior, no probation or suspended sentences, no nothing.
Ten years, period.

How to prevent this is
the problem. In my honest opinion, sales by dealers/distributors to
dubious characters should be punishable.

Who gets to define "dubious characters"? Sounds like you're proposing banning
the sale of a legal product on the basis of what the purchaser *might* do with
it in the future.

Bloomberg et al indeed try to
move the "culprit" label further up the supply chain, but then, there is
no evidence of gun manufacturers or distributors to help prevent the guns
from ending up in the wrong hands. Until gun
manufacturers/distributors/dealers make real honest efforts to prevent
guns from ending up in the wrong hands, I am in favor of trying to
prevent the initial gun sales.

What, pray tell, is the manufacturer supposed to do about it?

Parallel argument: Until car manufacturers/distributors/dealers make real
honest efforts to prevent cars from ending up in the hands of drunken drivers,
I am in favor of trying to prevent the initial car sales. How's that?

AND OF COURSE, real good penalties for
the miscreants who buy and use them illegally.

Attaching penalties to the purchase is pointless. Stiff penalties, rigorously
enforced, for their illegal misuse is the key. DAGS on "Project Exile".
