Abstract: This comment is in response to the article (arXiv:1006.0488) titled "A Non-Parametric Estimate of Mass Scoured in Galaxy Cores", and written by Hopkins and Hernquist. This comment politely mentions two relevant papers in which the main conclusion from Hopkins and Hernquist had already been published six years ago using the core-Sersic model. It then explains why Hopkins and Hernquist's concern about the core-Sersic model is not valid.
