You can google the San Francisco Zoo Tiger Escape. A female tiger, Tatiana, was taunted by three young fools....until she actually managed to escape her enclosure. Killed one on the spot, then stalked the other through panicking crowds and mauled him. Dozens of cops responded. All the reports of sightings of the tiger were from a far corner of the zoo. Some plainclothes cops went with a zoo employee to get some zoo workers out of a cafe.... and found the cat laying next to the second victim. They jumped out and started waving their arms to attract Tatianas attention. It worked...and she ran towards them. They jumped into the car and shut the doors.....but the window was rolled down. Cats head was in the window when the officer...now in his partner's lap, started shooting. Tiger then backed away, layed down under a Bush, and died. Crazy but true.
And for my fellow LEOs......you'll appreciate this. That night, someone cuffed a stuffed tiger holding a sign to the bench at the district station covering the Zoo. The sign said "I didn't do it. I've been framed !"
