Although it is undeniable that firearms are the weapons most often used in suicides and homicides, it does not follow that gun possession causes these incidents nor that a ban on gun ownership will prevent homicides and suicides. In Israel, Canada, and Switzerland, homicide and suicide rates are relatively low despite sizeable ownership of firearms, and in Great Britain, where legal handguns ownership if rare, the incidence of homicide by bombing and poisoning is higher than in the United States. Further, passionate advocates of bans on handguns fail to appreciate that rifles are far more lethal. Legislation should control safety in the use of firearms, particularly handguns. It is reasonable to ask any potential handgun owner to submit to screening procedures when applying for a gun purchase. Quickly administering a psychological test could detect signs of impulsivity and aggressiveness as well as warning signs of homicidal or suicidal impulses. Applications from persons with known criminal or mental illness histories could be rejected. In addition, before purchase of firearms, applicants would be required to produce a training certificate from an approved program that teaches the safe and proper use of firearms. A refresher course might be required before each license renewal. Nineteen references are provided.
