Fifty-seven years ago, when the Justices of the U.S. Supreme Court were an average of 8.5 years old, a U.S. Senate Committee was holding hearings on the perceived connection between juvenile delinquency and the fascination of immature minds with vivid enactments of murder, torture and ghoulish mayhem in the most popular youth entertainment of the day—comic books.  Those who pandered to this adolescent obsession with the morbid—the publishers—went to the Capitol to testify.  Among the most fervent, William M. Gaines—later the publisher of Mad magazine—insisted à la Mayor Jimmy Walker that no kid had ever been ruined by a comic book.  Gaines’s comments—and the skeptical responses of some committee members—sound quite familiar in the aftermath of the high court’s recent decision in Brown v. Entertainment Merchants Association.
