Interesting sentencing enhancement case from Washington state

Thanks to How Appealing, here is a little report on an interesting split state Supreme Court sentencing ruling today:

Should someone who is arrested for drunk driving, then taken immediately to jail, where a search reveals a small bag of methamphetamine taped to his sock, be subject to a sentencing enhancement for possessing a controlled substance in a jail or prison?  By a vote of 5-4, the Washington State Supreme Court answered "no" in a ruling issued today. The ruling consists of a majority opinion and a dissenting opinion.
