The APHF (founded in 1960) is the nation's first national police museum and memorial dedicated to American law enforcement officers killed in the line of duty. The Museum, through interactive displays, simulators and nearly 11,000 artifacts, educates the public about the history and current trends of American law enforcement. Featured at the Museum is a state-of-the-art 24 lane indoor gun range and is open to the public six days a week. The Memorial lists over 8,000 officers who were killed in the line of duty. Their names are permanently etched on the Memorial’s marble walls, which are added to once a year for Police Memorial Day. On Police Memorial Day (May 15th) the Memorial hosts thousands of police officers, family survivors and dignitaries. The event is a somber reminder that every 57 hours, a police officer is killed in the line of duty somewhere in America. The Police Museum houses two 501(c)(3) Nonprofit American law enforcement associations, The National Association of Chiefs of Police (NACOP) and the American Federation of Police and Concerned Citizens (AFP&CC). These associations strive to meet the ever growing needs of the American law enforcement community through a variety of programs and services.
