It's sad the alligator had to be put to death by the legalized poachers. Was there a reason the animal could not be relocated?
Was it because they wanted the meat and hide to sell? There was no reason for the killing. They stated the 'gator was docile, so it was no extraordinary threat.
I have captured animals such as alligators, and they can be relocated if you have contacts in confined protection agencies such as zoos, Department of Natural Resources locations or even the Savannah River Site. There's just no excuse.
