Overview of gun laws by nation

Gun laws and policy vary considerably around the world.

National gun laws by country and regions

Africa

Kenya

It is illegal in Kenya to own any type of firearm without a valid gun ownership licence as spelled out under the Firearms Act (Cap. 114) Laws of Kenya. Anyone who is 12 years or older can apply to privately own a gun. However, such persons must provide in writing to the Chief Licensing Officer (CLO) stating genuine reason(s) for their need to privately own and carry a firearm. It remains at the discretion of the CLO to make a decision to award, deny or revoke a gun ownership licence based on the reason(s) given.

Anyone seeking to hold a gun licence must pass the most stringent of background checks that probes into their past and present criminal, mental health and well as domestic violence records. Failure to pass one of these checks automatically bars one from being permitted to own a firearm. These checks are regularly repeated and must be continually passed for anyone to continue holding the gun licence. Failure to pass any of these checks at any stage, means an automatic and immediate revocation of the issued licence. Once licensed to own a gun, no permit is required in order to carry around a concealed firearm.

Law

Law is a system of rules that are enforced through social institutions to govern behavior. Laws can be made by a collective legislature or by a single legislator, resulting in statutes, by the executive through decrees and regulations, or by judges through binding precedent, normally in common law jurisdictions. Private individuals can create legally binding contracts, including arbitration agreements that may elect to accept alternative arbitration to the normal court process. The formation of laws themselves may be influenced by a constitution, written or tacit, and the rights encoded therein. The law shapes politics, economics, history and society in various ways and serves as a mediator of relations between people.

A general distinction can be made between (a) civil law jurisdictions (including Catholic canon law and socialist law), in which the legislature or other central body codifies and consolidates their laws, and (b) common law systems, where judge-made precedent is accepted as binding law. Historically, religious laws played a significant role even in settling of secular matters, which is still the case in some religious communities, particularly Jewish, and some countries, particularly Islamic. Islamic Sharia law is the world's most widely used religious law.

Gun

A gun is a normally tubular weapon or other device designed to discharge projectiles or other material. The projectile may be solid, liquid, gas or energy and may be free, as with bullets and artillery shells, or captive as with Taser probes and whaling harpoons. The means of projection varies according to design but is usually effected by the action of gas pressure, either produced through the rapid combustion of a propellant or compressed and stored by mechanical means, operating on the projectile inside an open-ended tube in the fashion of a piston. The confined gas accelerates the movable projectile down the length of the tube, imparting sufficient velocity to sustain the projectile's travel once the action of the gas ceases at the end of the tube or muzzle. Alternatively, acceleration via electromagnetic field generation may be employed in which case the tube may be dispensed with and a guide rail substituted.

The first devices identified as guns appeared in China around CE 1000. By the 12th century the technology was spreading through the rest of Asia, and into Europe by the 13th century.
