While I feel for what that kids parents must be going through, I think this is one of many examples for why we should need licenses to breed. What do you expect to happen if your kid is playing in an "alligator pond"? Sorry if that offends anyone, I don't mean it in a nasty way, I mean it in a "this could/should have been avoided" kind of way.
And not to take away from the tragedy here, but either that camera is super zoomed in, or you Americans are nut balls crazy! Be damned if I'd get that close to one of them bad boys...Don't bother using chain-linked fencing
Alligators/crocs don't always eat their kill immediately. Sometimes they stash it away for later on
