This document presents federal legislation (H.R. 3757) outlawing possession and use of firearms on school premises. Testimony for the "Gun-free School Zones Act of 1990" is offered in the form of discussion and prepared statements by panel members Edward P. Kovacic, Chief of Police, Cleveland, Ohio; Barbara Lautman, Director of the Center to Prevent Handgun Violence (Washington, D.C.); Joel Packer, Legislative Specialist with the National Education Association and National PTA; and Mark D. Widome, Associate Professor of Pediatrics at Pennsylvania State University College of Medicine. Based on the panel's evidence concerning gun violence on school campuses across the U.S. and the traumatic effects on schoolchildren, discussion was weighted overwhelmingly in favor of the proposed legislation, with few suggested modifications. Appendices contain a statement from the National PTA, a "Time" magazine article entitled "Shootouts in the Schools," a statement from the National Rifle Association Institute for Legislative Action, and the Center to Prevent Handgun Violence's 1990 report on gun violence in American schools.
