Armflap tantrums vs. actually prosecuting people (or orchestrating a program for people to surrender their shit) are two different things.Please see July 20th, 2016.
If she decides that, due to public safety, she is going to require all 'Assault Weapons' (as currently defined) that were obtained after 1994 to be removed from the state, permanently disabled or turned into police by a certain date; or face prosecution. Guess what, she can do that with what she did on the 20th and was allowed to stand. Does she have the stones is the only question - and due to the lack of real response from the House, Senate and Governor I would say it's already in the works. More so if the OP is accurate in her statement.
So far all we've seen from the AGs office is Bloviating, armflapping, limpwristing, grandstanding, and bullshit.
Judging her potential future actions based on what happened on the 20th is like believing Baghdad Bob. Healey might as well be an Al Sahaf clone.
