Every time I hear someone say that the war on terrorism or the latest governmental breach of civil liberties is making us safer, I think of the following exchange between Homer and Lisa Simpson (wish I could find the clip, but it doesn’t appear to be online):
Homer Simpson: Not a bear in sight. The Bear Patrol must be working like a charm.
Lisa Simpson: That’s specious reasoning, Dad.
Homer: Thank you, dear.
Lisa: By your logic I could claim that this rock keeps tigers away.
Homer: Oh, how does it work?
Lisa: It doesn’t work.
Lisa: It’s just a stupid rock.
Lisa: But you don’t see any tigers around, do you?
[Homer thinks about this, then pulls out some money]
Homer: Lisa, I want to buy your rock.
