The dozens of people who watched him grab the boy shouldn't have been there either.
You want to see a gorilla and can't afford Africa? YouTube it. Don't give good money to keep wild beasts under lock and key so you can peer at them like they're inmates in Bedlam. It's disgusting.
Had the stupid Americans thought at all about the animals they were gawking at, they would not have screamed like banshees when the boy fell into the enclosure.
They would have stayed nice and quiet, let the keepers do their job in trying to call Harambe away as they did two female gorillas, and defused the situation.
