Just heard on the news on KFYI. Arizona Governor Jan Brewer has signed the bill to remove the penalties for carrying concealed without a permit. This is phenomenal! It never stopped the bad guys.
That said... Anyone saying Wooah! and heading out with a .38 in your belt, You had better know what you are doing. The penalties for using it are far worse than just carrying one without a permit. Just ask that guy in Walmart. They have him on some 6 charges, at least one of which is sure to be "Criminally Stupid".
Alan Korwin's "The Arizona Gun Owner's Guide" is a good place to start.
