Silverback Gorilla Smashes Glass at Omaha Zoo

Frightened onlookers at the Omaha Zoo scattered yesterday as one of the gorillas suddenly rushed the glass of the enclosed exhibit and smashed it. A Redditor captured this footage of the Silverback in question, who had been fighting with another male just prior to the incident. Photos of the bleeding, angry animal later surfaced after the fact.
Having witnessed a similar incident at my local zoo in which a male gorilla raced up to the glass of his enclosure and suddenly punched it hard enough to shake the structure after a man pressed up against it from the other side, I can say how terrifying such a happening is, even though the glass wasn't smashed. Such accounts give me uneasy feelings about keeping these intelligent, powerful animals caged up, frustrated and bored.
