Last night, while watching the trouble in downtown LA, I saw one guy pick up a trashcan and start to throw it at an abandoned police car. But then he notices a guy standing on the hood, busy whacking at the windshield with a board. So he waits. He puts the trashcan down and politely waits for the other guy to finish and step down, back into the crowd. Then he re-hefts the can and heaves it at the car's roof.

Just because he's a vandal doesn't mean he's rude.
