Then they’ll sue under Heller.
And ten years later we may see something from it (if there still is a State of California by then).
I think you know I agree with the goal. It is the political means here that I think are counterproductive. Rely upon a court to uphold your rights while ignoring public perceptions and, in the long run, we'll all lose.
There are better means. For example, I think the best thing gun activists have done is teach women about concealed carry. The public demonstrations at ranges with augmented interest in female participation have been effective. Let's put our efforts there instead of making life difficult for the police that we hope to induct as our natural allies.
