Gray writes "École Secondaire Mont-Bleu has banned all personal electronic devices and suspended two 13-year-old girls after one uploaded to YouTube a camera phone video of their teacher yelling at the other. After the video was posted on the popular internet video site, the teacher was so embarrassed that he stayed home from work, where he remains on stress leave. The teachers' union is now trying to get all personal electronic devices banned from all schools in Western Quebec."
