Interesting tidbit: Other cameras at Columbine

I found when looking through the witness reports that there were additional CCTV cameras at Columbine High School, but only the cameras in the Cafeteria were recording at the time of the incident. Additional CCTV cameras were placed near the library hallway, science hallway, and administration office, but these cameras were only set to record after school hours.

From Andrew Marton's witness report, 11k pg. 000995. (Was with Niel Gardner during the incident)

Quote :

Marton stated daily he would take the tapes out in the morning and replace them with the prior week's tapes. Marton stated the videotape cassettes were only kept for one week, and then taped over. Marton said there are timers on the surveillance cameras that started at 1700 hours, through 0600 hours. Marton stated there was a camera for the Library which faced out, one facing the Principal's Office door, and one in the area of Science [You must be registered and logged in to see this link.] which viewed the rear commons area.
