I don't know if they've yet passed a bill requiring a mh eval report for a license? That's a hotly contested point on the conservative side, it's too much government intrusion, is the heart of that matter.

MA has some of the more stricter of laws and I don't believe that is here, here is more about storage safety.

With that in mind it could also be parental concern about danger to self, not always about danger to others. Which seems fair enough in the big picture of things.
