From InstaPundit:

Restrictive firearm legislation has failed to reduce gun violence in Australia, Canada, or Great Britain. The policy of confiscating guns has been an expensive failure, according to a new paper The Failed Experiment: Gun Control and Public Safety in Canada, Australia, England and Wales, released today by The Fraser Institute. . . .

Disarming the public has not reduced criminal violence in any country examined in this study. In all these cases, disarming the public has been ineffective, expensive, and often counter productive. In all cases, the effort meant setting up expensive bureaucracies that produce no noticeable improvement to public safety or have made the situation worse.

Gun laws don't reduce crime
