Like criminals care whether or not carrying a gun is legal or not.
So we must make it harder to get a gun.
Besides, Concealed Carry would only help crminials... for instance, if a criminal was walking to shoot someone, but was stopped by a cop:
Cop: Is that a gun you're hiding?
Criminal: Er, why, yes, yes it is.
Cop: Can I see your Concealed Carry permit?
Criminal: Here you are...
And then the criminal would walk on and shoot a family of 8.
Ha, you are so nieve. I won't hold it against you, because you are so young.
