This book describes the different legal approaches taken by eighteen countries and the European Union (EU) with regard to ownership, possession, and other activities involving firearms. The individual reports cover laws, regulations, and directives, in addition to statistical and other relevant information on gun control. The reports also address the availability or lack thereof of a constitutional right to bear arms under foreign law; the scope of firearms-related activities that are subject to licensing; conditions for the issuance of licenses, including background checks of the applicant's mental and criminal history; training, testing, and storage requirements; weapons bans; and registration procedures, including the use of a central register in some of the countries surveyed. Many reports describe legislative history and trends, which in some cases were influenced by rising crime levels or incidents of mass shootings. A bibliography of selected recent English language materials is included.
