California v. SunAnnotate this Case
Late one night, two officers were piloting a police helicopter when a laser struck their cockpit multiple times. The windshield on the aircraft refracted the light from the laser throughout the cockpit, which restricted the officers’ visibility and gave one of them a headache. However, they were able to trace the source of the laser to appellant Mengyan Sun's apartment, and officers arrested appellant there a short time later. Appellant was charged with two counts each of assault with a deadly weapon and aggravated assault on a peace officer. He argued on appeal his prosecution for that general offense was precluded by statutes that specifically pertain to the unlawful use of a laser. The Court of Appeal agreed and reversed his convictions for assault with a deadly weapon. The Court published its opinion "to underscore the continued vitality and adaptability of the venerable Williamson rule, which we believe has aged well."
