The designer of the billboard, Lenard Liberman, is a Jewish lawyer from Mexico. His family came here, took US citizenship, but remain Mexican. They own multiple Mexican language radio and TV stations in California and Texas. He said that the billboard was designed to boost viewer-ship for the upcoming May sweeps. Cinco de Mayo, don't you know. Anyone who is offended by the billboards, well, too bad, Los Angeles is an Hispanic city.
