I can't understand the America government allows his citizens carrying guns. Guns are dangerous for the people who lost their mind. People are usually lost their mind after a arguement, drinking a lot and worrying about something. The angry blind their eyes and they need to relax yourselves. The right way is to do some sport or listen music. But if a gun in an angry person's porket, he maybe choose shoot. That's dangerous for other people who are enjoying their life.
