Just Deserts -- is that, like, an Arab travel agency?
In effect, you're bringing back the stocks. Not a bad idea. I've thought for a long time that putting shoplifters in the stocks in front of the store they robbed, with the object they stole and a sign that says "I stole from Wal-Mart" would stop shoplifting in its tracks. You could use this in school too. A sign that says "I spit at my teacher" or "I plagarized my term paper" or "I am a bully" over a kid in the stocks would bring back the idea that there are standards and consequences for breaking them.
I've always thought the stocks in the public square was the perfect penalty for non-violent crimes. (For the violent offenders, bring back public stoning.)
