I know that (personal) security is a VERY subjective thing but things **feel** like they have improved quite a lot in Miami-Dade during the last 3 or 4 years.
Anyway I believe the article was referring to anti-terrorist security, and that makes some sense as usually terrorists try not to mess up their "points of entry" <g> (And I'm not talking about the Mariel boatlift, that's way in the past. I'm talking about the airport, and the long coast with plenty of private boat traffic)
BTW: Central Florida is also a gorgeous place to live...
