Gottfried and Yan's Quantum Mechanics has the following discussion of photon angular momentum:
$$ \boldsymbol{J}_\textbf{sp}= -i\hbar\sum_ka^\dagger_k\times a_k = \hbar \sum_{k\lambda} \lambda \hat{\boldsymbol{k}} \, n_{k\lambda}.$$
"Hence the one-photon state of of momentum $\hbar\boldsymbol{k}$ has angular momentum $\pm\hbar$ along $\boldsymbol{k}$, that is to say the photon has helicity $\pm1$. Note the striking difference from nonrelativistic angular momentum: the spin has no component along the direction of motion."
This seems to me to be directly contradicting itself. Does the photon have angular momentum along its direction of motion?
