From the Hawaii Reporter:

In general, lawful gun ownership is a pretty simple matter. The Founders established gun-owner rights so that citizens would possess and be able to exercise the universal right of self-defense. Guns enable their owners to protect themselves from robbery and assault more successfully and more safely than they otherwise would be able to. The danger of laws like the D.C. handgun ban is that they limit the availability of legal guns to people who want to use them for legitimate reasons, such as self-defense (let alone hunting, sport shooting, collecting), while doing nothing to prevent criminals from acquiring guns.
