Concealed weapon
In Mexico civilians cannot own guns since it has been illegal since 1968. However, most Mexicans own guns, even fully automatic weapons. In South Africa there are about 6 million licensed handgun owners. There is also a very large backlog of those applying for a license. Illegal guns can be easily bought off the streets. About 2,000 guns are stolen per month from licensed owners making it the largest source of illegal guns.
