I suspect the SCOTUS will take the case. If so, I also expect it will rule 5-4 in favor of the individual right to keep and bear arms, and it will also rule 5-4 in favor of declaring the Federal statute at issue here unconstitutional. The wailing and whining after that happens should be quite entertaining.
I realize that you asked this of others but my reading is that this paragraph means that the privileges and immunities guaranteed under the constitution will be reciprocal throughout the states of the union. I suggest that this was amplified in Amendment 14, Secton 1 in the equal protections clause.
I have been reading all of your flags betty, even if I do not always reply. I wish for you blessings as we this week commemorate our redemption and the victory of life over death.
BTW did you ever get around to the book by Roger Penrose I suggested ? Best to you, bb.
