Jack Hanna agrees "1000 percent" with zoo's decision to kill gorilla
The Cincinnati Zoo sparked outrage for killing an endangered gorilla after a four-year-old boy made it past a barrier and into an enclosure 15 feet below. The zoo says the boy was dragged and thrown before the 450-pound gorilla was shot and killed. Jack Hanna, the director emeritus of the Columbus Zoo and Aquarium joins "CBS This Morning" to explain why he agrees with the zoo's decision and takeaways from the incident.
