The alligator was removed from the Endangered Species list in 1987 and is actually hunted in Louisiana. It should be a simple matter to determine if this is an alligator or a camian, native to southern Mexico and South America. (Go to Wikipedia) It sounds to me like they know it is an alligator and they know it is no longer on the endangered species list, yet they want to get him for killing it.
They're hunted big time here in Florida as well. The FWC issues gator hunt permits - every year they issue more and more permits. It doesn't slow down the growth of the alligator population, though. There are more of them today than ever since they were placed on the Endangered Species List.
It used to be a rare occurence to hear about someone being killed by an alligator in Florida. Now, I hear of at least two fatal attacks per year, sometimes more.
