Yes. And the zoo is going to pay big for their bad choices. They should have made the enclosure secure. But they chose not to and people died.
We are lucky that the zoo's negligence did not harm anyone else.
Sadly you are probably right, the zoo will pay a price but I can at least take comfort in believing that the families will donate that money back to the zoo so they can invest in making the zoo safe for future animal lovers to visit.
