Al has a better memory than I do!
As someone wiser than I said after SCOTUS heard the oral arguments, the first thing is to get the 2A ruled as an individual right. The next thing is to seek incorporation against the states. After incorporation, the next question to be asked will be "Is the right sufficiently fundamental as to outweigh government imposed delays to exercising the right?" This would include waiting periods, purchasing a "safety" card or first obtaining a "permit" to own or purchase.
If we get the delays and special-expense permits overruled it sets the stage for addressing permits to carry openly or concealed and laws against both. How can an individual exercise his right to "bear" arms when laws prohibit
both carrying openly and concealed?
