I can't speak for Florida... but I can speak to the South. Not that Florida is all the South. In Florida, the further north you go the further south you get.
Policing in the South seems, from my experience, to be different in a few ways. It's still more the same than it is different, but here goes:
1. Less or no unions, right to work states, more administrative power. If the boss is a good guy, things work very well. If he's not, people eventually just leave and go elsewhere. Seems to be self-correcting.
2. Radio traffic is highly professional. Lots of codes, you will eventually think in code.
3. Lots of radio channels. One Mass. city PD had two of its own and 3 more shared throughout the county. A slightly smaller Miss. city PD has 7 of its own, plus another 6 shared throughout the county. Get used to switching channels to run a tag, chat, call a detective, whatever.
4. Less case law, particularly at the state level. Most court decisions that apply will be federal. The state Supremes aren't going to be big on providing extra rights beyond those guaranteed by the US Constitution.
5. Less money in general for everything at the agency. Cars are kept longer. Computers are kept longer. Buildings are often hand-me-downs, sometimes in pretty bad shape. Think Taunton PD in the 90's... or worse. (Hopefully they've got new digs by now...)
6. Somewhat less restrictive policing. See #4 above. No worries about putting someone in cuffs, taking them to PD for some questioning. Maybe they get released, maybe they get arrested. If there is PC, bring them in.
7. Less tracking of traffic citations. If the officer wants to hold a ticket for, say, No Proof Liability Insurance and give the motorist a few days to come up with proof, he/she can do that, then tear up the ticket if they desire.
8. Somewhat less is expected of a line officer. If you get a good arrest, a detective will take it over and put together all the statements, evidence chain of custody, etc. It is less common for a street cop to handle an entire felony, even if the entire thing falls into their lap and they have all they need.
9. Guns. Everybody has them. Pretty much everywhere. Stop a little old lady and she's likely to mention there's a magnum in the center console. On the good side, most departments let you carry a little something (or a whole lotta something) extra on duty.
10. Odd laws. Stuff will trip you up in ways you won't expect. In my state, Sheriffs can't run radar. Highway Patrol has no jurisdiction off of state highways. Florida and other states have their own oddities.
11. Maybe no civil infractions. In some states, everything is either a felony or a misdemeanor. You can still give a ticket, and an arrest for a MV violation is considered bad police work (without some other factor) but it IS lawful.
12. A variety of economic levels. There will be some VERY poor areas. They will have poor schools, few job aspects, little opportunity. Others will be better off, or even wealthy. Your police experience will vary WILDLY depending on this.
13. Gangs. LA influenced and Chicago influenced. Get yourself to a basic gang school as early as you can.
14. Prisoners. They will serve you food at the academy, wash your patrol cars, empty your trash... they may even have keys to your offices. Don't ask me why, and I work on a college campus so we don't deal with that, but it happens.
15. Details. Sorry, we dig up the street without much in the way of traffic control. Detail cop? Hell, sometmes there isn't even a traffic cone or flashing light. Just two guys with shovels. One may have on a traffic vest, the other may have on a prisoner uniform.
16. Military. Lots of bases, all services. Not at all uncommon, if you are near one, to see old school buses bringing the troops to the mall and the movies on Friday nights.
17. Weather. It gets cold and raw (or seems like it since I've lived here ten years) but it also gets so damned hot and humid you will need to acclimate. Hydrate, you will survive.
Anyways, there's more but that will give you an idea. I'm sure others will jump in with some Florida specifics.
Good luck!
