HONOLULU (AP) — Mike Lambert heard fewer illegal fireworks exploding in his suburban Honolulu neighborhood in the months after a chain of blasts at a house party last New Year's Eve led to the deaths of six people, including a 3-year-old boy. As the director of Hawaii's Department of Law Enforcement, Lambert wondered if the tragedy had sparked a shift in Hawaii residents' penchant for igniting illegal fireworks. In some neighborhoods, it would be common to hear loud booms any time of day or night — for sporting events, celebrations or no apparent reason at all.
