Your link is a 42 page document. It's probably very interesting and it's certainly an area that interests me in particular, but summary would have been nice to see alongside the link. I doubt you're going to see much discussion here, because of that reason.
Let's cut to the reforms, listed below with their headers.

Might be a case where posting a summary reduces the chance people will read the article sufficiently that it's best not to post a summary.
A well-known American federal appellate judge, Alex Kozinski, has written a commentary on systemic biases and institutional myths in the criminal justice system.
The basic thrust of his criticism will be familiar to readers of the sequences and rationalists generally. Lots about cognitive biases (but some specific criticisms of fingerprints and DNA evidence as well). Still, it's interesting that a prominent federal judge -- the youngest when appointed, and later chief of the Ninth Circuit -- would treat some sacred cows of the judiciary so ruthlessly.
This is specifically a criticism of U.S. criminal justice, but, ceteris paribus, much of it applies not only to other areas of U.S. law, but to legal practices throughout the world as well.
