Really? Try it in downtown Los Angeles some day. You will very shortly be on your way to jail and your weapon will be on its way to becoming part of a manhole cover.
Not fair? If you really believe that why are you not camped out on the capitol steps in Sacramento trying to change it? A lot of things in life are not fair or right or just. We all pick our fights.
This doesn't make the States infringing daily on our Rights in any way correct in their abuse of power. It just means we're putting up with the abuse instead of taking our Rights back...
"The prohibition is general. No clause in the Constitution could by any rule of construction be conceived to give to congress a power to disarm the people. Such a flagitious attempt could only be made under some general pretence by a state legislature. But if in any blind pursuit of inordinate power, either should attempt it, this amendment may be appealed to as a restraint on both."
Game. Set. Match.
