The goals of licensing and registration include making every individual responsible for his or her firearms and providing police with information with respect to firearm ownership and registration. Those goals can only be achieved by keeping the registry up to date, including the current addresses of licensees.
Persons who have been prohibited or who are unlicensed for whatever reason cannot own or register firearms. The updated addresses of such individuals are thus not personal information that is necessary to manage the firearms program. The Privacy Act only authorizes the collection of personal information by a government institution that is directly relevant to the management of its programs and activities. It is sufficient, in the case of prohibited individuals or unlicensed individuals, for the police to be advised that these individuals cannot lawfully possess firearms.
