I hope not...Last place I'd want to be a police officer is in San Francisco and I live near there.

That said, I don't think there is any evidence that they were inside the enclosure. In fact it is very unlikely due to the sheer wall of 12.5 feet. They would have been eaten inside the tiger cage. It is more likely that the tiger grabbed a foot dangling over the side or just jumped over and attacked them where they fell.
