Silly trial court! Sex offenders aren't "banished" from Los Angeles simply because state law says that they can't reside within half a mile or so of any school or park where children regularly gather. There are still plenty of places where they can live in L.A. -- in particular, thre are plenty of bushes and a couple of $5000/month rental homes that are indeed located 2000 feet away from the barred locales.
So if, upon being released from prison as a sex offender, you're able to afford a $5000/month rental, you're totally golden. Welcome to L.A.! And if not, you're still not "banished" from L.A. It just means you have the pleasure of being homeless and living inside a bush. Call it a permanent "camping" trip and enjoy!
