The Louisiana government confiscated guns from the people of Louisiana to punish those insufficiently affluent to hire private armed security forces, exempt from the confiscation. They did so only because the ruins of the City of New Orleans then lay solely within international waters and therefore somehow temporarily outside the territorial jurisdiction of the United States of America, famed for its Second Amendment guarantee against infringement of the right of the People to keep and bear arms. Louisiana authorities alternatively might reason that those among the people insufficiently wealthy to hire private security forces did not qualify as full legal free persons, a bizarre legal status akin to that of Dred Scott and Jane Roe’s baby.
That argument doesn't hold "water". If you check my video in post 11 above, you will see dry streets where the confiscations, stand offs and arrests are being conducted.
