Columbine Records

The FBI says the two teenagers who carried out the nation's worst school shooting appeared articulate, mature, intelligent and insightful as they discussed their plans in videos made months before the Columbine High School massacre.

But the public may never get to see or hear video and audio tapes Eric Harris and Dylan Klebold made because of authorities' fears they could be used to plan copycat attacks.

Jefferson County Sheriff Ted Mink said yesterday that he'd release diaries kept by Harris and Klebold and nearly one-thousand pages of other documents seized from the teenagers' homes after the April 20th, 1999, attack.

But Mink says the videos could be distributed instantly around the world over the Internet and help other emotionally disturbed teenagers plan similar attacks.

Harris and Klebold's parents have two weeks to ask a judge to review Mink's decision to release the documents, which include yearbook messages, planning calendar entries and schoolwork.

Harris and Klebold killed 12 students and a teacher before taking their own lives at the high school.
