Comment on “Self-interacting Elko dark matter with an axis of locality”

In this comment we show that the statement in Ahluwalia et al. [Phys. Rev. D 83, 065017 (2011)] that the existence of Elko spinor fields imply in an axis of locality is equivocated. The anticommutator $\{\Lambda (\mathbf{x},t),\Pi (\mathbf{x},t)\}$ is strictly local.
