My thoughts on Whittier:
I didn't like the campus. It felt/looked like a high school more than a law school. The law library is big and spacious however.
It seems likemost Whittier grads get jobs in the public sector (DAs office/Public Defender's office). I don't know what the job opportunities are like for Whittier grad in law firms...from Chapman's stats it seems like the majority of the chapman grads work in the private sector (sometihng like 66%) so I'd be a little worried that the private sector jobs would be taken by Chapman grads.
I did a review on Chapman v. Whittier here: http://www.lawschooldiscussion.org/prelaw/index.php/topic,55394.0.html
Check it out & let me know if you have any questions.
Generally I would say Whittier over Western State, Chapman over Whitter.
