force. The word "Emergency" was etched above the "Honolulu" on the seven-point star badges of police officers. For the duration of World War II, the Honolulu Police Department was forced to impose restrictions on civil liberties and hand people over for trial by a military judge. Martial law ended after the end of the war in 1945. The San José State Spartans football team served with the Honolulu Police Department for the duration of World War II; the team had played a game against the University of Hawaiʻi at Mānoa Warriors, but were stranded in Hawaii after the Pearl Harbor attack. Modernization The first instance of modernization came in 1952 with the introduction of the Honolulu Police Department's current badge. It was designed by Detective Alfred Karratti and embodies Hawaiian tradition and culture in its motifs. One feature that Detective Karratti kept was the use of the Pūloʻuloʻu or kapu staffs. They are symbols of law and order from ancient Hawaii. In 1976 Sister Roberta Julie Derby became the first female police chaplain in the U.S. and would later go on to win the medal of valor for defusing a hostage situation. The most aggressive programs of modernization for the Honolulu Police Department came in the 1990s. It was furnished with a fleet of new Ford Crown Victoria police cars equipped with on-board computers and a fleet of BMW police motorcycles. Officers also have the choice of using their own private vehicle for law enforcement duties as part of a subsidized program. The vehicle has sirens installed and removable blue police light which is put on the roof of the officers' car. On October 16, 1992, the Honolulu Police Department opened its multimillion-dollar state-of-the-art police headquarters in downtown Honolulu. The building was called Hale Maka'i and featured the latest technical advances of its time including a DNA crime lab unit, one of the first of its kind in the nation. Corruption and misconduct In October 2015, a former HPD officer was sentenced to 30 months in federal prison for an "unprovoked attack" on two men in a game room. In 2016, a retired police officer pleaded guilty to lying under oath as part of a conspiracy to frame a man for stealing a mailbox from the home of Police Chief Louis Kealoha. In 2017, Chief Louis Kealoha retired from the police department amid an FBI investigation into corruption and conspiracy.
