The Supreme Court is asked to hear about seven thousand cases a year. It takes about a hundred of them. Generally, it is looking for cases that have a major impact on Constitutional issues, or major Federal policy. I don't think this case will rise to that level.
In any event it would have to go through the Ninth Circuit first, and they would have to render a decision that the USSC didn't like. All that gets expensive, at some point the lawyers would cut a deal, which may be what the WTBS is hoping will happen.
