Almost 20 years ago, a juvenile mountain lion was spotted in a tree at a Palo Alto elementary school. The 100 pound cat was sitting in the tree eyeing all the yummy morsels on the playground. The cat couldn't be persuaded to leave all those excellent dinners, so they shot and killed him.
You can't imagine all the caterwauling by the locals about killing the pretty kitty. I'm not convinced they would have been singing a different tune if the cat had dined on that playground.
