"It's 10 p.m., Do you know where your children are?" The sound of this classic public service announcement filled living rooms across the nation between 10 p.m. and 11 p.m. for decades. The question raises the issue that parents must always monitor their children to keep them close, and therefore safe. Is this form of control constitutional? Furthermore, is it effective? This anthology interprets the issue of teen curfew from various perspectives.
