UPDATED: How many firearms in Walpole?
UPDATED 1/11/13: THE INFORMATION ORIGINALLY PUBLISHED HERE, PROVIDED BY WALPOLE DEPUTY POLICE CHIEF JOHN CARMICHAEL, APPEARS TO HAVE BEEN INACCURATE AND IS CONTRADICTED BY OTHER STATISTICS. BELOW ARE THE OFFICIAL STATISTICS, AS PROVIDED BY COMMONWEALTH MAGAZINE.
Resident Licenses to Possess a Machine Gun: 3
Firearm Identification Card: 160
Firearms Identification Card Restricted Chemical Propellant Only: 54
Resident Class A Large Capacity License to Carry Firearms: 792
Resident Class B Non-Large Capacity License to Carry Firearms: 1
Assault rifles are banned in Massachusetts, even though a federal ban expired in 2004.
Personal information about each firearm owner is not publicly available, in large part because it would allow criminals to map out who is armed in Walpole and who is not, and know where they should go to steal guns.
A helpful guide to Mass. gun laws, including a rundown of the different types of firearm licenses, is available here from MassLive.com.
Wikipedia also has an interesting guide. It is important to note that machine guns are, for the most part, banned, however, if you owned one before May 19, 1986, you could get grandfathered in.
