Have you looked at Aaron Greenspan's legal credentials ? He is (or atleast claims) a fellow of Stanford Law School. Has build a site for searching legal articles and in general spent considerable time researching this issue
I looked. I don't see him saying he has a JD. I don't see him saying he passed a bar exam. I especially don't see him saying he's a practicing lawyer. I have no idea what "fellow" means in this context, but he's not listed in the staff directory.
"Spending considerable time researching the issue" is not sufficient for not looking like an ass when acting as a lawyer.
There's a theoretical side to law, but it's mainly a practical art. Sort of like software. It would be hubris for somebody who has "spent considerable time researching software" to make his first coding project something big enough that it gets reported nationally.
