stations. This organization, the Boarding Services Bureau, had approximately 75 members, including one director, one lieutenant, five sergeants. Proposition 13, passed in 1978, limited the LAPD's ability to increase staffing at LAX. Airport Security Bureau 1981–1984 In 1981, the Security Division and the Boarding Services Bureau were merged, becoming the Airport Security Bureau. Substantial increases in authorized strength were connected to the 1984 Summer Olympics. Los Angeles Airport Police 1984–present In 1984, the Airport Security Bureau was renamed the Los Angeles Airport Police. At various times, it has organizationally been a bureau or a division of LAWA, depending on LAWA organizational structures; the "Bureau" designation is no longer used. In 1986, the LAXPD formed the Dignitary Protection Unit, which works closely with the United States Secret Service and Department of State to protect high security risk government VIPs. The LAXPD Dignitary Protection Unit participates as a key member of the LAX Airport Security Advisory Committee, and has representatives assigned to the Los Angeles Joint Terrorism Task Force and Los Angeles County Terrorism Early Warning Group. The LAXPD is a founding member of InterPortPolice and the Airport Law Enforcement Agencies Network. In 2004, the City of Los Angeles Personnel Department changed the LAXPD's job classification from Special Officer to Airport Police Officer. The LAXPD more than doubled in size between 1999 and 2005, from slightly over 400 officers to over 900. The LAXPD is a course presenter for law enforcement training under the auspices of the California Commission on Peace Officer Standards and Training (POST). The Airport Police fields over 20 patrol and explosive detection police dogs, maintaining the largest TSA canine explosive detection program in the U.S. within an aviation environment.

The Boarding Services Bureau uniform (1973–1981) consisted of midnight navy trousers, jacket and cap, white shirts. Supervisors wore gold colored accessories, such as tie bars, nameplates etc. In 1981, along with the merger of the Security Division and the Boarding Services Bureau, the uniform was standardized with dark navy trousers, cap, shirts, and a black jacket. All accessories were made in gold color for all ranks. The
