A little lengthy, but George Reisman makes some very compelling arguments. Really a good read.
Gun Control: Controlling the Government’s Guns: Let me say immediately that I too believe in gun control. However, I do so in the light of the knowledge that by far the largest number and the most powerful guns and other weapons are in the possession of the government. First and foremost, of course, the federal government, which has atomic and hydrogen bombs, as well as ballistic missiles with which to deliver them, fleets of warships, and thousands upon thousands of tanks, planes, artillery pieces, machine guns, and lesser weapons. State and local governments also possess considerable weaponry, though less than the federal government. But just the revolvers, rifles, shot guns, clubs, tear gas, and tasers in their possession are capable of causing serious injury and death, and frequently do so.
