Wash. Rev. Code § 9A.49.001
The legislature finds that lasers are becoming both less expensive and more accessible in our technologically advanced society. Laser devices are being used by individuals in a manner so as to intimidate and harass. This creates an especially serious problem for law enforcement officers who reasonably believe they are the target of a laser sighting device on a firearm. Additionally, emergency service providers, service providers, and others who operate aircraft or motor vehicles may be negatively affected to the point of jeopardizing their safety as well as the safety of others. In order to address the misuse of lasers, the legislature hereby finds it necessary to criminalize the discharge of lasers under certain circumstances.
