Computer Pornography CMU'S RIMM WON'T TESTIFY AT SENATE Researcher's name removed from hearing witness list by Lillie Wilson Marty Rimm, Carnegie Mellon University's embattled chronicler of cyberporn, won't testify at Monday's US Senate Judiciary hearing on children and computer porn after all. Washington sources close to the committee said Rimm's name was removed from the hearing witness list after recently published attacks on Rimm's research methods, which the committee felt had discredited the study and cast doubts on the ethics of its author. Sen Charles Grassley, R-Iowa, called the full judiciary committee hearing to address the need for his pending bill, the "Protection of Children from Computer Pornography Act of 1995", which would make it a crime to knowingly transmit pornographic images to minors. Grassley had publicly cited Rimm's 85-page study, _Marketing Pornography on the Information Superhighway_, to support his legislation. Deen Kaplan, a leader of the anti-pornography National Coalition for Children and Families who had appeared on ABC's "Nightline" defending the study, was also dropped from the witness list, one Washington source said. The Rimm study was published by the Georgetown Law Journal, a publication of Georgetown University Law School, where Kaplan serves as a member of the law review. The Rimm study -- which did not undergo peer review -- claimed, among other charges, that "83.5% of all images posted on Usenet are pornographic". The survey had, in fact, targeted private on-line bulletin boards that billed themselves as pornographic or adult -- not bulletin boards selected at random. Carnegie Mellon has meanwhile launched its own investigation. As "truth and integrity are fundamental" to university research, Provost Paul Christiano is about to convene a committee "to examine in more detail the issues that have been raised about the study", a recent CMU announcement read. "They'll be investigating the ethical concerns about the study, and the way it was done", CMU spokesman Don Hale said. Rimm, a computer science researcher who wrote the controversial study last year as a CMU undergraduate, recently hired a lawyer, Hale said. The lawyer's name was not available. The study, which was highlighted in Time magazine's recent cover story on computer pornography, had initially been hailed by a number of anti-pornography crusaders, including the Christian Coalition, legal scholar Catharine A. MacKinnon and Grassley. Grassley's hearing Monday is now slated to include 10 witnesses to testify on "Cyberporn and Children: The Scope of the Problem, the State of Technology, and the Need for Congressional Action". The list includes three parents, an assistant general counsel for a commercial on-line service, and a self-described "victim". -- Pittsburgh Tribune-Review, Saturday, July 22, 1995, p.A1
