The states do have ultimate authority, IF they so choose. They have never acted upon their authority to call a constitutional convention and approve changes by 3/4ths if the state legislatures.
THIS, I can agree with. If the states want to amend the Bill of Rights, that's fine. If they want to make torture and unfair trials legal, that would be the way. Amend the Bill of Rights.
Until then -- well, after then, too -- the B.o.R. applies to them as well.
