A lesson in self-defense

"The lesson the porcupine teaches is that you
don't have to be strong enough to defeat a
predator to avoid being that predator's lunch. It
suffices to be an expensive meal. Predators tend
not to dine on porcupines because a serving of
porcupine tends not to be worth the mouthful of
quill that it costs." -- John T. Kennedy

A nation of guns at home comes to mind here.
