Assuming agreement with you in principle, why not work closer and exclusively with state legislatures, where such laws would be less vulnerable to constitutional invalidity? Especially in light of the fact that different states define ‘stalking’ diversely, as well as the elements for misdemeanor versus felony stalking. Also, individual states could tailor reinstatement of 2nd amendment rights based upon their diverse mental health infrastructures.

On the surface, the only remarkable change you suggest is that a misdemeanor, as opposed to a felony, would disqualify a citizen from lawful firearms possession. It seems unlikely state legislatures would offer much resistance, because as you surely know, even many ‘gun-friendly’ states already have laws requiring surrender of firearms upon domestic abuse allegations (i.e. before trial).

So again, why Congress? If passed by Congress what you propose probably violates US v. Lopez, Jr., 514 U.S. 549 (1995) and would be stricken down at the first challenge. But it is probably kosher if passed by each state individually, tailored to that state’s needs.

Thank you in advance for your reply.
