Ninth Circuit Says City Can Stop the Billboards

As a City Councilman years ago, Mike Woo initiated a moratorium on billboards in Los Angeles. But since then he's watched billboards proliferate to the point where he says they're now a threat not only to the visual landscape, but to public safety as well. Woo, now sits on the Planning Commission, looks at the proliferation of digital billboards and a recent court case that weighed First Amendment rights against public safety.
