7) Congress could ban the manufacture and sale of bullets and magazines. Given the massive number of bullets and magazines already owned by the public and readily available instructions for making them, this wouldn't stop any determined killer like Adam Lanza. On the other hand, it would lead to a massive black market with tens of millions of previously law abiding Americans buying bullets by the bucketful from back rooms across the country.
8) Congress could also ban the manufacture and sale of guns. Again, that would lead to the creation of a massive black market, but it would also leave roughly 300 million guns in the hands of the American people. In other words, if Adam Lanza had decided to wait until AFTER that law was passed to go on his killing spree, it would have been the same sad story.
9) Then, there's the most extreme step of all: Congress could ban the ownership of guns. One problem: In the vast majority of cases, the government has no record of who owns guns and who doesn't. In most places, those records are kept at the gun store level and are not updated. If the gun is lost, stolen, given away or sold by the individual, there is no record of it. This is a feature, not a bug, and it's designed to prevent exactly the sort of confiscation we're discussing here. So, even if all guns were made illegal, it would be very difficult to enforce, most people wouldn't turn their weapons in and there would probably be two hundred million guns left in the hands of the American public. Would a man like Adam Lanza still be able to acquire a weapon in that situation? Come on, he KILLED HIS OWN MOTHER for a gun; so you can be sure he'd have gotten one elsewhere.
10) Let's go Steven Spielberg on this problem and assume space aliens show up and use some bizarre technology to get rid of all guns. Well, even so, fire and explosives would still exist and as Brian Palmer has noted in Slate, those can be even more effective killers than guns.
Guns aren't even the most lethal mass murder weapon. According to data compiled by Grant Duwe of the Minnesota Department of Corrections, guns killed an average of 4.92 victims per mass murder in the United States during the 20th century, just edging out knives, blunt objects, and bare hands, which killed 4.52 people per incident. Fire killed 6.82 people per mass murder, while explosives far outpaced the other options at 20.82. Of the 25 deadliest mass murders in the 20th century, only 52 percent involved guns.
If gun control advocates like Barack Obama, Michael Bloomberg and Michael Moore, all of whom have armed guards protecting their safety, succeed in making guns less available for law abiding citizens, it wouldn't stop another Newtown massacre, but ironically it would make it easier for rapists, gangs or even the next Adam Lanza to hurt innocent people.
