If you don't get into USC or UCLA, I say go to whatever regional L.A. school you do get into. If you can't make a top 20, you're almost always better off going to a school located where you want to practice.
Also, realize that Santa Clara is just barely a Tier 2.
And I don't know a lot about Chicago-Kent, but I'm thinking if I were hiring for an L.A. firm and you said you went to school in Chicago, I'd say, "Oh yeah, U. Chicago or Northwestern?"
The point is, even if you get a great education at a school outside of Southern CA, when you eventually go to work there, you're likely to get the "Sorry, but no one at our firm has any experience with graduates from your school."
If you go to a school in the area, at least you may have some connections, or some common ground to get your foot in the door.
Go to Southwestern and spend three years schmoozing with the locals.
Thanks for the input. That helps a lot, and it was along the lines of what I was thinking. Southwestern claims to be the place to be for Entertainment Law. Hope there's some validity behind that. Also, Alphalyrae, congrats on your acceptances!
