Gun control (or firearms regulation) refers to laws or policies that regulate the manufacture, sale, transfer, possession, modification, or use of firearms. Some of these regulations attempt to control crime or reduce the harmful effects of violence. They vary greatly around the world. Some countries, such as the United Kingdom, have very strict limits on gun possession while others, like the United States, have relatively few restrictions (although policies vary from state to state).
Proponents of gun control generally argue that widespread gun ownership increases the danger of gun violence. Opponents of gun control and advocates of gun rights argue that gun control does not reduce crime, violates individual liberties, and reduces the ability of citizens to defend themselves.
