Today's decision is a start, but my prediction is that it will take 20-30 more years of effort and litigation over what constitutes "reasonable restrictions" to try to roll back the damage to our rights that has already been done.
Also, while we have won one more battle, the war is far from over. To quote Winston Churchill, "It is not the beginning of the end, but, perhaps, it is the end of the beginning."
Also, we need to be even more watchful now, since we can expect some real counter-attacks from the left. Also, never kid yourself that these laws have anything to do with reducing crime, except as rhetoric to fool the foolish. Historically, weapons laws have always been about extending the control of some elite over a peasantry, for the fun and profit of that elite. It was true during the Tokagawa Shogunate in Japan, when only Samurai could own swords. It was true in the post-Civil War South, when gun laws were passed to make sure that ex-slaves would be defenseless when the Klan came to call. It was true in Great Britain when the National Firearms Act of 1920 was passed as a crime control measue, but really out of fear of a Bolshevik-style revolution in the aftermath of WW I. It was true in NYC, when the Sullivan Law was used to ensure that only Tammany Hall thugs had guns on election day. The examples could continue almost indefinitely.
