Because of gun politics in Brazil, all firearms are required to be registered with the state; the minimum age for ownership is 25[1] and although it is legal to carry a gun outside a residence, extremely severe restrictions were made by the federal government since 2002 making it virtually impossible to obtain a carry permit.[2] To legally own a gun, the owner must pay a tax every three years to register the gun, currently at R$ 60,[3] and registration can be done via the Internet or in person with the Federal Police.[4] Until the end of the 2008, unregistered guns could be legalized for free.[5] The total number of firearms in Brazil is thought to be around 17 million[2] with 9 million of those being unregistered.[1]
