If he doesn't walk, he'll fly to a country that doesn't have an extradition treaty with the US. Roman Polanski comes to mind, among others
Personally I could give a Rats @ss. The majority of the criminal court system in California is corrupt, mainly due to jurors that want to write books or whatever.
I have concern that he will walk. This is an inherently tough case to prove. He chooses victim who will be certain to have shady and defective parents - for whom motive will be easy to show. He has (had) substantial cash and uses it to intimidate and silence victims.
I heard the repulsive Geraldo Rivera comment that he was not guilty and that he found it impossible to believe that Jackson would engage in abuse immediately after the crisis caused by the Bashir documentary. Which just goes to show that Geraldo doesn't know much. The recidivism rate on childe molesters/abusers is very high - for a reason. They cannot control their impulse to abuse children. It's not as if it would be reasonable to expect Michael Jackson to take inventory of the state of his career and to elect not to molest a child because of the potential impact it would have in the aftermath of the PR catastrophe of that documentary.
If he walks - I say hats off to Sneddon for taking on this inherently difficult prosecution. At least he wasn't willing to stand by like Michael Jackson's "posse" of bodyguards, press flaks and enablers.
