The Cynic's "Con Law in One Easy Lesson"

Via Arms and the Law, a credible (?) humorous (?) (pick one) take on Constitutional Lawyering:

"First, draw the desired curve. Then, plot the data. If time permits, do the experiment."

The author of the piece (found here) is a Con Law prof. He continues:

I used it as a parable about how not to do constitutional interpretation -- and as a description of how some interpreters (courts, law professors, certainly many first year law students) seem actually to do Constitutional Law, at least from time to time: Pick the desired result, choose an interpretive methodology to match, and then, time permitting, do some research to find supporting evidence.

Hell, if that's all it takes, why spend 3 years paying folks like Esenberg?
