Brandishing the First Amendment

Book excerpt: Tamara R. Piety argues that increasingly expansive First Amendment protections for commercial speech imperil public health, safety, and welfare; the reliability of commercial and consumer information; the stability of financial markets; and the global environment. Using evidence from public relations and marketing, behavioral economics, psychology, and cognitive studies, she shows how overly permissive extensions of protections to commercial expression limit governmental power to address a broad range of public policy issues.
