Criminal lawyers are expected to be experts in everything--biology (DNA), economics (motives for many crimes), psychology (for everything), probability ("beyond a reasonable doubt"), etc.
That is asking a lot, so I'm not going to say who wrote the following nonsense in his book on the "economic analysis of law." (The highlights are from Google books because I stumbled on it while search for those words.)
Correction: The guy who wrote this is an economist. Go figure.
