Sure, it's easy to mock airport screeners when you hear about how many items they miss, but have you ever tried it yourself? Go on, give it a try. After identifying only an abysmal 20 percent of the threats on the conveyor belt myself, I'll ease up on the criticism. Some. Maybe.

Thanks to the MeCo listserv for the pointer, and for the link to this story about how people are trying to sneak liquids and liquid-like substances onto planes.
