It sounds like you probably choose not to own a weapon. That's fine. It's your business. The problem is that you can't retroactively make everyone's guns disappear, or prevent new ones from being made and distributed, whether via 3D printing or someone's home metal shop. We could ban guns, like we did alcohol during prohibition, but then only the criminals have guns, just like only the criminals had booze back then. What did that do to the value of alcohol on the black market? It skyrocketed and created the mob, who became extremely wealthy and powerful, draining valuable police/investigative man-power (oops! Person-power. Sorry.
) and resources to play a never ending and losing game of whack-a-mole trying to police the ban. Once alcohol skyrocketed in value, you then saw many regular citizens decide to produce and sell bathtub gin. Prohibition did nothing intended and many negative things unintended. So, I'm curious... How would you, personally, implement "gun control" in a way that addresses these potential issues if you had the power?
Edit: Since you mentioned the sawed-off shotgun ruling, let me give you an example of how that ruling accomplished nothing, besides the example of them still existing as home defense weapons after the ruling (they didn't magically disappear). You can go online now and buy a Mossberg Shockwave 590 or a Remington 870 TAC-14 for $300. These are 14" barrel pump shotguns with an overall length of about 26". This is functionally identical to a sawed-off, just as easily concealed, just as deadly.
"Featuring a 14 3/8 – inch barrel, pistol grip, and an overall length of 26.5-inches, the 590 Shockwave does not fall under the purview of the National Firearms Act and does not require additional paperwork or the payment of a tax stamp for transfers* (learn why)."
So what good did that ruling actually accomplish?
