Also, the US government wouldn't nuke their own people. If they did, they won't target Florida. Since those are off the table, we're talking about a traditional war. As we've seen with Afghanistan, the US military doesn't know how to fight an asymetric war. Good luck trying to get people that live in the hundreds of square miles of swamp.
Arms are a big factor. Europe is at far greater risk of authoritarian regimes because their people are effectively disarmed. A few single shot shotguns won't do much. If only their population had ready access to AK47s, AR 15's or event bullpups out of Israel.
I think this bears emphasis: Pretty much every crime report provided to or made by the police within Florida, silly or sublime, is available to the public [1]. This is a gold mine for people who want to run a "stranger than fiction" web site. It could distort one's view of what Florida is like.
