I think the notability comes from the notability of the user, and how it was used. for example John Allen Muhammad is one man, not an organization, but his use of the Bushmaster XM-15 is very notable. I would also like to note that the Glock pistol article does not list all the police forces that use that sidearm. Anyway, NYPD is more notable than a small town police department, and that is because of size, anyone who says otherwise is kidding themselves. 67.176.160.47
