Paul Campos, the University of Colorado Law School professor who writes the incendiary Inside the Law School Scam blog, is back at it, with a new book of advice for would-be law students.

Campos said he was inspired to write Don’t Go To Law School (Unless) — an electronic book slated to go on sale on Amazon.com this week — in part because so many prospective law students have asked him for counsel about whether they should enroll.
