"Try to halt violence by restricting gun ownership and you won't halt violence. But you will create entire classes of new criminals — people who make paperwork errors, violate technical specification of the law, or rebel against the new restrictions. And you'll create new bureaus, new enforcement arms, new prisons to punish them. You'll make hordes of lawyers and bureaucrats very happy. Organized criminals will be grateful to the naive moral crusaders ("useful idiots") as they profit by selling an illegal product. And ordinary street criminals will bless fools, legislators, and "leaders" for making their job so much safer."
