Time and again society has found this works.

According to the evidence, every mass murder in recent times has been halted, in the final analysis, by shooting the murderers, or threatening to shoot them, with guns.

Members of the press corps continue to debate the subject, despite the evidence. Sources speaking privately say the media consciously reject this fact. In stark contrast, self-defense incidents using guns are suppressed, by news-media policy, and do not appear on the public stage.

An excellent write up about the censorship of firearms used in self defense appears here —http://www.wnd.com/2014/07/usa-today-ad-campaign-features-armed-heroes

Multiple reports of self-defense, accomplished by shooting criminals, appear as paid space in USA Today, which otherwise censors such reports:http://www.gunlaws.com/TheFirstRespondersReport.htm
