Was the Killing of the Cincinnati Gorilla Justified?

Claim: The killing of the Cincinnati Gorilla was justified.

Evidence: "The decision to use lethal force had been a difficult one. A tranquilizer would have taken several minutes to neutralize the animal, prolonging the risk. The dart could also agitate the animal, the zoo said, and cause a violent reaction."

Explanation: The zoo security team’s saved the child’s life. If the zoo security team would've used a dart it would've caused a violent reaction. A tranquilizer would've taken several minutes to neutralize the gorilla. Their decision to use a lethal weapon was justified. The gorilla could've hurt the little boy if dragged him a little harder.
