I will admit that there is no way that child should have been able to get into that enclosure.
With that being said, the only viable solution to save that child was the killing of the gorilla.......
That was a full grown male gorilla that was already on edge when we witnessed it grab the kid by the arm and take off across that waterway. There was no telling what could or would have happened after that.....
They have incredible strength and according to Jack Hanna who was interviewed this morning, he has witnessed them crush coconuts with one hand.........It's unlikely it could have been bribed into letting the child go by offering it a banana.......
