"* In 1982, the city of Chicago instituted a ban on handguns. This ban barred civilians from possessing handguns except for those registered with the city government prior to enactment of the law. The law also specified that such handguns had to be re-registered every two years or owners would forfeit their right to possess them. In 1994, the law was amended to require annual re-registration.  "
* Since the outset of the Chicago handgun ban, the percentage of Chicago murders committed with handguns has averaged about 40% higher than it was before the law took effect.
