  The aim of this paper is to critically examine claims that it is possible to
construct point-localized state vectors for the photon. We supply a brief proof
of the impossibility of this. Then it is found that the authors making these
claims use a non-standard scalar product, not equal to the quantum-mechanical
one. This alternative scalar product is found to be proportional to a Dirac
delta function in position for the state vectors they use, but the remaining
elements of the proof, namely satisfying all three Newton-Wigner criteria, are
lacking.
