National gun laws
The majority of small arms are in the hands of private individuals - worldwide, around 60% of guns are possessed by civilians. There is a strong correlation between firearms ownership and gun death rates, especially for handgun ownership, as handguns are concealable and so commonly used in crime.
In 2006, the UN sub-commission on human rights endorsed principles to prevent human rights abuses by civilians with guns. Many countries regulate:
- types of weapons permitted. For example, prohibiting fully automatic weapons, or semiautomatic rifles. Given their use in crime, some countries also prohibit civilian possession of handguns.
- users of guns. Licensing the users of guns might involve requiring users to prove they have a genuine need of a firearm, also background checks to investigate whether the user is likely to be a risk to themselves or others.
- uses of guns. For example, prohibiting carrying or firing guns in a public place.
Essential to enforcing the above regulations is firearm registration, linking every weapon to its last legal user and so identifying any point of diversion. This is part of a marking and tracing requirement.
