You know the old joke, the one about the man in the park tearing newspaper into strips and throwing it on the ground.
“Why are you doing that?” someone asks.
He says, “I’m doing it to keep the elephants away.”
“But there are no elephants here!”
“I know,” says the man, “It’s working.”
Replace “elephant” with “terrorist’ and you have the TSA.
Only no one is laughing at that joke.
