Apparently not. A quick Google search discloses that while the population is showing slow signs of a comeback, its basically limited to the very Southern tip of Florida, and is a long way from being safe. Here is a good link:

Incidentally, while visiting the Alligator Zoo in Orlando 19 years ago, I saw a a few crocs mixed in with the gators. The most fascinating thing was that there was one croc which would continually swim through a sea of gators and leap up to get the chicken-on-a-rope in the main pond.
It was almost as if it was smarter than the gators, or maybe could jump out of the water further.
Its a shame that many are accidentally destroyed because *diots think that they're killing a nuisance "gator".
If you can tell the difference between a Golden retriever and a German Shepherd, you ought to be able to figure out if you're looking at a croc or a gator.
1. Gators are darkish-greenish in color;
Crocs are lighter-colored and brownish;
2. Gators have wide rounded snouts;
Crocs have longer, more narrow snouts;
3. When a gator closes its mouth all you can see are its upper jaw teeth (overbite);
When a croc closes its mouth, you can see a number of large lower-jaw teeth sticking up, as well as upper jaw teeth hanging down.
The American croc is not as big as some other species and is not as aggressive as the African and Australian varieties...
I wouldn't know an American croc from any other croc, but I'd sure know the difference between a croc and a gator.
Croc's "smile". The edges of their mouths turn up and remind me of a cupid's bow mouth, like some girls have. Gators are just linear.
