Kentucky students were caught with 36 handguns on school property or at school events during the 1998-99 academic year, according to a state study detailing the frequency of such violent incidents. The study, the first of three, was released Monday the same day a student in Philadelphia allegedly shot a vice principal in the leg. During the 1998-1999 school year, students also were caught with 24 other types of guns and almost 400 other weapons, according to the Kentucky school crime analysis. Numbers for individual school districts were unavailable, but a gun incident has not been recorded in Warren County schools since 1994, Warren County Superintendent Leonard McCoy said. He had not yet seen the report. With more than 11,000 students, avoiding any gun-related problem for five years is a statistic in which to take pride, he said. The state report contained information from 1,437 schools and from each of the states 176 school districts about 640,000 students in all. Boys were twice as likely to be victims of crimes on school property and about three times as likely to be the offenders, the report said. In addition, black students were almost twice as likely as whites to be victims or offenders in school crimes, the report said. The 1998-99 school year included 875 aggravated assaults, 3,256 simple assaults, 2,237 drug violations, 151 arsons and 664 larceny or thefts. The Center for School Safety at Eastern Kentucky University, which completed the study, plans to release individual school district breakdowns in late October and individual school statistics in November, a spokeswoman for the group said.
