Where is the ACLU?

The Mayor of Salem, Oregon has demanded that a local business owner remove the mural (above) painted on the side of his business. The businessman faces a $200 fine. The mayor’s actions came about as the result of ONE complaint. The article fails to mention the rationale behind the mayor’s actions.

PJ Media has additional information regarding the mural. It seems that the city regulates “public art.” Wonder how many taggers have run afoul of this?

The ACLU was there to defend Nazis wanting to parade in Skokie, Illinois. They were there to defend nude dancing as a form of expression. Defending a business owner because he put up a mural found to be objectionable by the local government would seem to be right up their alley. Where is the ACLU?
