I agree 100%. Race has nothing to do with this.
The elephant in the room is this, the fault lies not with the child, not with the parent, not with the Gorilla, but with the Zoo. It was their responsibility to assure the public that there would be no possible entry into the Gorilla compound, yet a 4 year old found a way in, and was put in danger. The shoot a dart into the gorilla would have caused additional danger to the child, the Zoo personnel knew this, which is way killing to Gorilla was the only immediate option they had.
The fault, was entirely the Zoo. And they know it.
