@Setanta,
It is NOT a transfer of wealth, and IT IS justified, to use Federal funds to feed, clothe and house the inmates of Federal penitentiaries FOR AS LONG AS THEY REMAIN IN A FEDERAL PENITENTIARY.
It is among the normal federal costs of Article I Section 8, "To regulate commerce with foreign nations, and among the several states, and with the Indian tribes";
and
to pay the direct and implied normal federal costs for the processes of Amendment VI, "In all criminal prosecutions, the accused shall enjoy the right to a speedy and public trial, by an impartial jury of the state and district wherein the crime shall have been committed, which district shall have been previously ascertained by law, and to be informed of the nature and cause of the accusation; to be confronted with the witnesses against him; to have compulsory process for obtaining witnesses in his favor, and to have the assistance of counsel for his defense."
