Playtime Theaters and Sea-First Properties purchased two theaters in Renton, Washington, with the intention of exhibiting adult films. About the same time, they filed suit seeking injunctive relief and a declaratory judgment that the First and Fourteenth Amendments were violated by a city of Renton ordinance that prohibits adult motion picture theaters from locating within one thousand feet of any residential zone, single- or multiple family dwelling, church, park, or school. Does the city have the right to enforce such an ordinance? Explain.
