The policy of the State of Washington encourages openness of records. The Open Public Records Act declares, "The people of this state do not yield their sovereignty to the agencies that serve them. The people, in delegating authority, do not give their public servants the right to decide what is good for the people to know and what is not good for them to know. The people insist on remaining informed so that they may maintain control over the instruments that they have created. The public records subdivision of this chapter shall be liberally construed and its exemptions narrowly construed to promote this public policy."
