As much as I don't like that Baker didn't make a bigger issue of her failure to respond to his letter, her failure to respond to letters from Legislators, and that he did not speak out against her, the two out of context quotes really don't say much.
"has the authority and the jurisdiction" isn't even a complete statement and is technically correct. But Healey went well beyond this with her creating a similarity test, confusing guidance, and ignoring 20 years previous interpretation.
"If there are people that are selling weapons that violate the assault weapons ban in Massachusetts, it's important to them to get clarified," out of context, does not state that he believes Healey is correct, is technically correct, could just as easily have been spun as Baker wanting the AG's statement clarified because of the confusion it caused, which is what his letter asked for.
To me, these are non-statements. I want to see the whole conversation. Not just the media spin. They may be as presented here, and they may not be.
