There are some bad apples (in any country). My best guess is it should be the local government deciding who should be allowed to carry a gun. If Qatar had a process in place, I would most definitely go through it. One way to look at it is a criminal can get a gun anytime they want without following any rules. If law abiding individuals were allowed to meet whatever standards the local government sets forth, why should they not be allowed to carry? In places where the private individual is armed, there is a possibility of crime rate reduction which makes everyone safer. Less people will commit an act of violence if an armed police officer is standing right next to them. If more people had the same qualifications and training, it could help deter crime.
