Estimating Law Enforcement Firearms

From the Small Arms Survey:

Law enforcement small arms present a contradiction of visibility and scarcity. Of the roughly 875 million firearms in the world, in virtually all large countries law enforcement weapons are the most visible in public. They are also the smallest major category of small arms, covering some 25 million fire-arms, compared to approximately 200 million military and 650 million civilian guns world-wide (Small Arms Survey, 2007). The agencies covered in this analysis include law enforcement agencies responsible for domestic security, i.e. police, gendarmes, official paramilitaries, and smaller agencies such as customs, game management, and prisons
