Well considering it was written on the brick and then attempted to be scrubbed off it's unlikely the hate crime would stick - hence them mentioning in the article it was most likely scrubbed off to avoid hate crime charges (which is a surprisingly amount of foresight for neo nazis honestly).

And the cops were contacted, but shockingly they haven't made any arrests. Even though members of the (presumed) same group have made appearances throughout the city since then.
