Are you sure "adding another law" is the solution?
Another solution would be some recall elections charging some prosecutors with misfeasance for their failure/refusal to bring charges against those in Government who violate these laws (specifically RCW9.41.290;RCW9.41.300).
Somehow I feel that adding another law would just add to the number of those that are currently ignored and will also be ignored.
Which is more feesible: Adding one more law to strike down hundreds of other laws, ordinances, etc in conflict with state preemption or recall elections, charging government employees, etc??
