Marty, Rabbi, M14...
From your experience in the legal gun business and/or gun ownership, how can guns be reduced in the Black Market?
How do you make illegal sales and possession more illegal, so the people who break the law now will stop?
You understand the absurdity of this, yes?
Here's the thing:
Laws exist not to prevent crime but to punish people after they commit one.
It is impossible to enact a law that will prevent people from breaking the law -- laws cannot prevent people from committing crimes; as such, it is fallacious to restrict the actions of the law abiding in order to prevent people who do not obey the law from breaking the law..
And so, what do you do? Punish people when they commit crimes.
