I found this series done by KCET LA on outdoor advertising in Los Angeles on Rami Tabello's illegalsigns.ca. This quote from part 3 of the series embodies the distrust which develops when a city fails to take care of its residents before it takes care of the outdoor advertising industry and huge profits. "It doesn't really seem like anybody cares and I don't really believe the city is capable of doing anything about it." With critical legal as well as safety issues being ignored by the outdoor advertising industry in LA and the lack of public support for outdoor advertising, it is amazing the city has not been more cavalier with the problem.
