GREELEY, Colorado (AP) — Greeley school officials say privacy laws prevent them from letting a parent see a surveillance videotape after his son was disciplined for a fight on a school bus.

Mike Moskalsk says he asked to see the video taken on the bus after his son was suspended for 10 days after the April fight. Moskalsk says his son didn’t start the fight but was defending himself.

Greeley-Evans School District officials say that to release the tape, they would have to get permission from the parents of all the children shown, or digitally blur their faces. They say either option would cost too much.

About 80 percent of the district’s buses have surveillance cameras. Officials say surveillance tapes are reviewed only if problems are reported on a run.
