I think it has more to do with the idea that if the gator was close enough to attack a human, then it was probably used to being around humans, and therefore would not be afraid to attack again. It's odd logic, I dunno. My dad used to be a Wildlife Officer or whatever they're called nowadays for the state of Florida. He used to bring home gators all the time and move them to other places in the state. I remember one time he brought home 2 babies and a mom gator, left the mom in the back of his pickup and put the two babies in our turtle tank. He told me not to tell mom they were in there and that he'd be right back! -lol- He needed to move the older gator first and was waiting for instructions on where to put the babies. I guess he knew mom wouldn't have liked gators in the house!
