Googling the acronym came up w/ this : New England Coalition to Prevent Gun Violence.
And from an old post from our old buddy Gonzo at the "Gun Guys" (who has effectively stopped blogging except for the occasional copy/paste after the funds dried up):
They’re an affiliate of Freedom States Alliance, a national group which also runs the FSA Network, of which this site is a member.
They're still listed after the FSA merged w/ States United (who just got another $100K grant from the Joyces).
Color me shocked. Another 'grassroots' organization that a light breeze could blow over w/ little to no membership and funded by the Joyces.
