For years Washington state has used the state patrol as a revenue source, hiding behind the shadow of special enforcement by using undercover and unmarked vehicles for traffic enforcement. This is a travesty. If they are truly concerned with safety, then a marked vehicle is much more likely to cause a change. If that is the intention. A direct statement in RCW 46.08.065 stating that these vehicles CAN'T be used is required, since the way that things are stated now leaves it open to interpitation.
