Wildlife folks want to keep denying things to actually protect the critters. If they admit to having them,, the next thing is Bubba Joe Redneck will be wanting to kill them all. Of course the media will have all the animal lovers out in force to try & restrict hunting them AND other critters.
Several states have laws protecting them,, yet also claim there are not any in the State. A buddy of mine asked a game warden some years back what would happen if he shot one. the reply was he'd get arrested & charged. He replied with something like; "If you say there isn't any in the State,, how can I be charged with killing a non-existent critter?"
He was firmly told he would be charged because even though the official word is that none are here,, to protect the POSSIBILITY of any being here,, they are a protected species.
