Why put a child up on a railing when there was nothing there to catch them should they fall? What was the mother thinking?

Zoo officials said there is also a mesh barrier beyond the railing, but Kraus said it was designed to catch small objects such as cameras, and not humans.

Major Crimes Lt. Kevin Kraus said the child’s mother had lifted him onto a railing on an observation deck for the exhibit housing 11 painted dogs.

“The mother picked the child up, put him on the railing,” Kraus said. “Almost immediately after that, he fell into the pit.”He apparently slipped over a 5-foot-tall railing at the observation deck outside the Safari Plaza area, one of the exhibit’s two observation decks, and into netting. The boy then fell from the netting into the exhibit containing 11 painted dogs
