So, if somehow magically we could scoop up every pistol, rifle and shotgun on the planet and dump them all in the ocean tomorrow, by the following day (if not sooner) a multi-billion dollar black market would instantly arise, and within a very short time most of the millions upon millions of guns then produced would be in the wrong hands.

Suppose, though, that the effort did inconvenience a few evil minds, so that guns no longer factored into their schemes. Well, considering that the Columbine school shooters had as their back-up plan blowing up a gas grill canister surrounded with nails in the cafeteria at lunchtime, that Timothy McVeigh used a truck full of plain old fertilizer, that the 9/11 hijackers used nothing but box-cutters to obtain four jetliners loaded with fuel, that the Boston Marathon bombers used pressure cookers anyone can buy at Walmart, I wouldn't be sleeping any easier at night.

One thing, though... and this is aside from the damage done to our Constitution - a document that has protected us far more than we would care to admit these last couple of centuries - anyone putting into practice a policy of even partial disarmament of the public at large will bear responsibility for any lives lost due to good people having no recourse to firearms.
