JULY 7--One of the Columbine High School gunmen prepared a report on the danger of guns in schools more than a year before carrying out a deadly attack on teachers and fellow students. Eric Harris's December 1997 school report was included in more than 900 pages of Columbine-related documents released yesterday by Colorado investigators. In grading the Harris report, a copy of which you'll find below, a Columbine teacher judged it "thorough & logical" and gave the paper a 69 out of 75. Noting that, "a school is no place for a gun," Harris concluded that the use of metal detectors and an increased police presence "are a great start to fight against guns in school." On April 20, 1999, Harris and Dylan Klebold--armed with shotguns and semiautomatic weapons--murdered 12 classmates and a teacher before killing themselves. (5 pages)
