Please note HR 2267 and 2287 that are both into JOINT COMMITTEE ON PUBLIC SAFETY AND HOMELAND SECURITY for review, these just make it virtually impossible to get a firearm license in Mass plus if you have one, you cant go anywhere with it. One day Ill wake up in NH!

I think the language surrounding location does not apply to CCW. Just like the firing within 500 ft. of a dwelling does not apply if you are defending yourself.
