The law you mention is one we Floridians prefer to call the "Castle Doctrine." The "Shoot First" crap comes from the anti-gun sheeple. The Castle Doctrine allows Floridians to defend themselves, For example, previously, if some armed creep smashed into my home, I had to wait until he indicated that he was about to pull the trigger before I could pull mine. Now I Can reasonably assume that the same creature, smashing into my home with a weapon, is not here to announce that I have just won the lottery but rather means to hurt me, I can now defend my castle and blow his sorry a## away. If I am in a parking lot and am surrounded by three tough "Gangsta's" making threatening overtures, previously I had to make every effort to escape because they were not displaying a weapon. Now in this instance, since I am a 66 yr old, overweight, out of shape, slow running citizen, they themselves constitute a threatening weapon and if I feel myself in danger to my life or limb, I can use a firearm to defend myself. Does this give you a better picture? It is Constitutional and most likely, as in any shooting will cause a legal mess - which I will be alive to participate in.
