He was arrested in Washington state so California's laws are irrelevant anyway. Under 40 grams in Washington might as well be legal, it's just a minor misdemeanor carrying only a fine. In this case he's getting hit with a $622 fine, but when he goes to court, it'll probably be reduced and possibly dropped. In the end, there's a chance he pays more for driving 74 in a 60. Not a big deal at all.
And really, are you surprised?
