Florida has a law that establishes minimum sentences, it was commonly called the 10-20-Life law and it's been around since the late 90's.How about this?
Use a gun in the commission of a crime and 10 years are added to your jail sentence. 2nd time you use a gun during a crime, we add 20 years.
Use a gun during a crime and someone dies, even if you didn't pull the trigger, it's an automatic death penalty.
Use a gun to defend yourself or someone else, and you are protected by the law.
Edit to add we also have a justifiable use of force law
Oh and another edit to add that Florida has issued over 1 million concealed carry permits
