Open Carry.
Due to the nature of some people, I believe that Open Carry laws would help out more than just Concealed Weapon. Do you honestly think that someone would rob you or try to kill you if they see a gun strapped to your side? I believe that if you want to Open Carry, you need to be able to pass a drug test, mental fitness test and a check up every 6 months for a drug and mental test. If you can not pass, you should not be able to buy a gun. If you do pass, you should be able to get a card showing that you have passed and have the right to Open Carry.
