  In a recent paper (arXiv: 0801.4566) it was shown that all global energy
eigenstates of asymptotically $AdS_3$ chiral gravity have non-negative energy
at the linearized level. This result was questioned (arXiv: 0803.3998) by
Carlip, Deser, Waldron and Wise (CDWW), who work on the Poincare patch. They
exhibit a linearized solution of chiral gravity and claim that it has negative
energy and is smooth at the boundary. We show that the solution of CDWW is
smooth only on that part of the boundary of $AdS_3$ included in the Poincare
patch. Extended to global $AdS_3$, it is divergent at the boundary point not
included in the Poincare patch. Hence it is consistent with the results of
(arXiv: 0801.4566).
