Jim,
Different municipalities may have different restrictions that add to the state law. Packing.org is generally pretty much on the money. If your District Attorney waffled on when he would indict and no bill, then he is hedging his bets. You might want to consider what you do where you live very carefully.
Just as a licensed driver is expected to know the laws governing the use of a motor vehicle, a licensed concealed carry gun owner is expected to know the laws governing the carry and use of his weapon. The driver's license exam is not intended to teach you the laws of the road. A CCW class is not intended to teach you the law concerning lethal force. It is intended to insure you meet the minimum requirements for carry as defined by your state. From what I understand Florida has some of the easiest requirements to meet, and the best reciprocity in the country. In fact, I almost got a Florida CCW to take advantage of that reciprocity. (No, you don't have to be a resident of Florida to get a Florida CCW.)
Best regards,
XB
