Do you have a link to the law? I would REALLY like to read it.
You bet that part of the law got their attention. And it's about time that all local would-be dictators are forced under threat of personal prosecution to allow law abiding people to exercise Constitutionally protected rights in ALL categories of the law without infringement by local laws and ordinances. It's yet to be seen whether or not all of FL's local prosecutors will enforce the new law concerning that issue. The heavily populated southeastern part of the state is very liberal and anti-2nd Amendment, and local officials will no doubt resist enforcing the new law as long as possible. I haven't lived in FL for over 15 years, but I well remember the Nazi-like officials who dominated local governments in that part of the state when I did live down there.
Next step: apply that same concept to those authorized to enforce the law, a la the Canton, OH JBT recently featured on YouTube. It would only take a few house-forfeiting judgements against the badged bad-guys that kill dogs, raid the wrong house and generally violate the civil rights of law-abiding licensed firearms carriers to get a handle on who's the boss.
